::stage Egg:: During fall season, salmon eggs are laid in gravel beds at the bottom of streams and lakes. Deposited several feet below the water surface, they are protected from exposure to indirect sunlight. The eggs are spherical in shape and slightly translucent with pinkish or reddish coloration. While in the egg stage, the developing organs can be seen easily through the translucent covering. Hatching usually takes place within 2 - 3 months after the eggs are laid. ::stage Alevin:: The water flow and temperature are very crucial for hatching salmon eggs. Alevins, which are 1-inch long, are characterized by presence of abnormally large eyes, attached to a bright orange sac, which is nothing, but the nutritive yolk. For nearly 3 - 4 months, the newly hatched alevins reside in the gravel nest, feeding on the yolk that hangs below their body. ::stage Fry:: The next stage is that of fry. Once the nutritive yolk is absorbed, the young fry come out of the gravel nest. The young fry swim and feed on small planktons and aquatic plants. Many times, the salmon fry become easy prey for larger fish, insects, and birds. In their entire life, the mortality rate for salmons is highest when they are in the fry stage. ::stage Parr:: When a fry mature to parr stage, they measure about 6 inches. During this parr stage, vertical markings develop on their body and flanks. Species like king salmon immediately migrate to the oceans during or after fry stage. In other species, parr feed and grow in the freshwater streams for approximately 1 - 3 years, before they begin their journey towards the ocean. ::stage Smolt:: In the smolt stage, the developing salmons reach the estuary - the connecting point where a river meets an ocean. The smolts turn silvery white in color, while losing their vertical stripes. In general, they swim in groups along with others and frequently visit the oceans for feeding purpose. With time, smolts body gets adjusted to saline water of the ocean. ::stage Adult:: The body marking of adult salmons is very distinctive, which differs significantly from one type to another. Based on the species in question, adults may spend anywhere around 3 - 7 years in the ocean, after which they migrate upstream to their birthplace for spawning. Adult salmons stop eating and develop different body colors; males retain bright colors, while females turn darker. After mating, the adult female lays eggs in the spawning site, and the entire journey is repeated all over again. Salmons have an average lifespan of 7 years. Most of the species inhabiting the Pacific Ocean die immediately after spawning?a behavior referred to as 'semelparity'. Very few species have the ability to spawn repeated times. Overall, the mortality rate after spawning is very high (40 percent to be precise), as adult spawners cannot spend long time in freshwater. In a nutshell, a salmon egg hatches in a river, migrates to sea, and returns back in the river for spawning. | In the fries stage, it stops eating | entailment | indicator |

::stage Egg:: During fall season, salmon eggs are laid in gravel beds at the bottom of streams and lakes. Deposited several feet below the water surface, they are protected from exposure to indirect sunlight. The eggs are spherical in shape and slightly translucent with pinkish or reddish coloration. While in the egg stage, the developing organs can be seen easily through the translucent covering. Hatching usually takes place within 2 - 3 months after the eggs are laid. ::stage Alevin:: The water flow and temperature are very crucial for hatching salmon eggs. Alevins, which are 1-inch long, are characterized by presence of abnormally large eyes, attached to a bright orange sac, which is nothing, but the nutritive yolk. For nearly 3 - 4 months, the newly hatched alevins reside in the gravel nest, feeding on the yolk that hangs below their body. ::stage Fry:: The next stage is that of fry. Once the nutritive yolk is absorbed, the young fry come out of the gravel nest. The young fry swim and feed on small planktons and aquatic plants. Many times, the salmon fry become easy prey for larger fish, insects, and birds. In their entire life, the mortality rate for salmons is highest when they are in the fry stage. ::stage Parr:: When a fry mature to parr stage, they measure about 6 inches. During this parr stage, vertical markings develop on their body and flanks. Species like king salmon immediately migrate to the oceans during or after fry stage. In other species, parr feed and grow in the freshwater streams for approximately 1 - 3 years, before they begin their journey towards the ocean. ::stage Smolt:: In the smolt stage, the developing salmons reach the estuary - the connecting point where a river meets an ocean. The smolts turn silvery white in color, while losing their vertical stripes. In general, they swim in groups along with others and frequently visit the oceans for feeding purpose. With time, smolts body gets adjusted to saline water of the ocean. ::stage Adult:: The body marking of adult salmons is very distinctive, which differs significantly from one type to another. Based on the species in question, adults may spend anywhere around 3 - 7 years in the ocean, after which they migrate upstream to their birthplace for spawning. Adult salmons stop eating and develop different body colors; males retain bright colors, while females turn darker. After mating, the adult female lays eggs in the spawning site, and the entire journey is repeated all over again. Salmons have an average lifespan of 7 years.

Overall, the mortality rate after spawning is very high (40 percent to be precise), as adult spawners cannot spend long time in freshwater.

::stage Egg:: During fall season, salmon eggs are laid in gravel beds at the bottom of streams and lakes. Deposited several feet below the water surface, they are protected from exposure to indirect sunlight. The eggs are spherical in shape and slightly translucent with pinkish or reddish coloration. While in the egg stage, the developing organs can be seen easily through the translucent covering. Hatching usually takes place within 2 - 3 months after the eggs are laid. ::stage Alevin:: The water flow and temperature are very crucial for hatching salmon eggs. Alevins, which are 1-inch long, are characterized by presence of abnormally large eyes, attached to a bright orange sac, which is nothing, but the nutritive yolk. For nearly 3 - 4 months, the newly hatched alevins reside in the gravel nest, feeding on the yolk that hangs below their body. ::stage Fry:: The next stage is that of fry. Once the nutritive yolk is absorbed, the young fry come out of the gravel nest. The young fry swim and feed on small planktons and aquatic plants. Many times, the salmon fry become easy prey for larger fish, insects, and birds. In their entire life, the mortality rate for salmons is highest when they are in the fry stage. ::stage Parr:: When a fry mature to parr stage, they measure about 6 inches. During this parr stage, vertical markings develop on their body and flanks. Species like king salmon immediately migrate to the oceans during or after fry stage. In other species, parr feed and grow in the freshwater streams for approximately 1 - 3 years, before they begin their journey towards the ocean. ::stage Smolt:: In the smolt stage, the developing salmons reach the estuary - the connecting point where a river meets an ocean. The smolts turn silvery white in color, while losing their vertical stripes. In general, they swim in groups along with others and frequently visit the oceans for feeding purpose. With time, smolts body gets adjusted to saline water of the ocean. ::stage Adult:: The body marking of adult salmons is very distinctive, which differs significantly from one type to another. Based on the species in question, adults may spend anywhere around 3 - 7 years in the ocean, after which they migrate upstream to their birthplace for spawning. Adult salmons stop eating and develop different body colors; males retain bright colors, while females turn darker. After mating, the adult female lays eggs in the spawning site, and the entire journey is repeated all over again. Salmons have an average lifespan of 7 years.

Most of the species inhabiting the Pacific Ocean die immediately after spawning?a behavior referred to as 'semelparity'. Very few species have the ability to spawn repeated times. Overall, the mortality rate after spawning is very high (40 percent to be precise), as adult spawners cannot spend long time in freshwater.

::stage Egg:: During fall season, salmon eggs are laid in gravel beds at the bottom of streams and lakes. Deposited several feet below the water surface, they are protected from exposure to indirect sunlight. The eggs are spherical in shape and slightly translucent with pinkish or reddish coloration. While in the egg stage, the developing organs can be seen easily through the translucent covering. Hatching usually takes place within 2 - 3 months after the eggs are laid. ::stage Alevin:: The water flow and temperature are very crucial for hatching salmon eggs. Alevins, which are 1-inch long, are characterized by presence of abnormally large eyes, attached to a bright orange sac, which is nothing, but the nutritive yolk. For nearly 3 - 4 months, the newly hatched alevins reside in the gravel nest, feeding on the yolk that hangs below their body. ::stage Fry:: The next stage is that of fry. Once the nutritive yolk is absorbed, the young fry come out of the gravel nest. The young fry swim and feed on small planktons and aquatic plants. Many times, the salmon fry become easy prey for larger fish, insects, and birds. In their entire life, the mortality rate for salmons is highest when they are in the fry stage. ::stage Parr:: When a fry mature to parr stage, they measure about 6 inches. During this parr stage, vertical markings develop on their body and flanks. Species like king salmon immediately migrate to the oceans during or after fry stage. In other species, parr feed and grow in the freshwater streams for approximately 1 - 3 years, before they begin their journey towards the ocean. ::stage Smolt:: In the smolt stage, the developing salmons reach the estuary - the connecting point where a river meets an ocean. The smolts turn silvery white in color, while losing their vertical stripes. In general, they swim in groups along with others and frequently visit the oceans for feeding purpose. With time, smolts body gets adjusted to saline water of the ocean. ::stage Adult:: The body marking of adult salmons is very distinctive, which differs significantly from one type to another. Based on the species in question, adults may spend anywhere around 3 - 7 years in the ocean, after which they migrate upstream to their birthplace for spawning.

After mating, the adult female lays eggs in the spawning site, and the entire journey is repeated all over again. Salmons have an average lifespan of 7 years. Most of the species inhabiting the Pacific Ocean die immediately after spawning?a behavior referred to as 'semelparity'. Very few species have the ability to spawn repeated times. Overall, the mortality rate after spawning is very high (40 percent to be precise), as adult spawners cannot spend long time in freshwater. In a nutshell, a salmon egg hatches in a river, migrates to sea, and returns back in the river for spawning. | In the fry stage, they live in gravel beds | not_entailment | indicator |
::stage Egg:: During fall season, salmon eggs are laid in gravel beds at the bottom of streams and lakes. Deposited several feet below the water surface, they are protected from exposure to indirect sunlight. The eggs are spherical in shape and slightly translucent with pinkish or reddish coloration. While in the egg stage, the developing organs can be seen easily through the translucent covering. Hatching usually takes place within 2 - 3 months after the eggs are laid. ::stage Alevin:: The water flow and temperature are very crucial for hatching salmon eggs. Alevins, which are 1-inch long, are characterized by presence of abnormally large eyes, attached to a bright orange sac, which is nothing, but the nutritive yolk. For nearly 3 - 4 months, the newly hatched alevins reside in the gravel nest, feeding on the yolk that hangs below their body. ::stage Fry:: The next stage is that of fry. Once the nutritive yolk is absorbed, the young fry come out of the gravel nest. The young fry swim and feed on small planktons and aquatic plants. Many times, the salmon fry become easy prey for larger fish, insects, and birds. In their entire life, the mortality rate for salmons is highest when they are in the fry stage. ::stage Parr:: When a fry mature to parr stage, they measure about 6 inches. During this parr stage, vertical markings develop on their body and flanks. Species like king salmon immediately migrate to the oceans during or after fry stage. In other species, parr feed and grow in the freshwater streams for approximately 1 - 3 years, before they begin their journey towards the ocean. ::stage Smolt:: In the smolt stage, the developing salmons reach the estuary - the connecting point where a river meets an ocean. The smolts turn silvery white in color, while losing their vertical stripes. In general, they swim in groups along with others and frequently visit the oceans for feeding purpose. With time, smolts body gets adjusted to saline water of the ocean. ::stage Adult:: The body marking of adult salmons is very distinctive, which differs significantly from one type to another.

Based on the species in question, adults may spend anywhere around 3 - 7 years in the ocean, after which they migrate upstream to their birthplace for spawning. Adult salmons stop eating and develop different body colors; males retain bright colors, while females turn darker. After mating, the adult female lays eggs in the spawning site, and the entire journey is repeated all over again. Salmons have an average lifespan of 7 years. Most of the species inhabiting the Pacific Ocean die immediately after spawning?a behavior referred to as 'semelparity'. Very few species have the ability to spawn repeated times. Overall, the mortality rate after spawning is very high (40 percent to be precise), as adult spawners cannot spend long time in freshwater. In a nutshell, a salmon egg hatches in a river, migrates to sea, and returns back in the river for spawning. | In the young salmon fry stage, they live in gravel beds | entailment | indicator |
::stage Egg:: During fall season, salmon eggs are laid in gravel beds at the bottom of streams and lakes. Deposited several feet below the water surface, they are protected from exposure to indirect sunlight. The eggs are spherical in shape and slightly translucent with pinkish or reddish coloration. While in the egg stage, the developing organs can be seen easily through the translucent covering. Hatching usually takes place within 2 - 3 months after the eggs are laid. ::stage Alevin:: The water flow and temperature are very crucial for hatching salmon eggs. Alevins, which are 1-inch long, are characterized by presence of abnormally large eyes, attached to a bright orange sac, which is nothing, but the nutritive yolk. For nearly 3 - 4 months, the newly hatched alevins reside in the gravel nest, feeding on the yolk that hangs below their body. ::stage Fry:: The next stage is that of fry. Once the nutritive yolk is absorbed, the young fry come out of the gravel nest. The young fry swim and feed on small planktons and aquatic plants. Many times, the salmon fry become easy prey for larger fish, insects, and birds. In their entire life, the mortality rate for salmons is highest when they are in the fry stage. ::stage Parr:: When a fry mature to parr stage, they measure about 6 inches. During this parr stage, vertical markings develop on their body and flanks. Species like king salmon immediately migrate to the oceans during or after fry stage. In other species, parr feed and grow in the freshwater streams for approximately 1 - 3 years, before they begin their journey towards the ocean. ::stage Smolt:: In the smolt stage, the developing salmons reach the estuary - the connecting point where a river meets an ocean.

In other species, parr feed and grow in the freshwater streams for approximately 1 - 3 years, before they begin their journey towards the ocean. ::stage Smolt:: In the smolt stage, the developing salmons reach the estuary - the connecting point where a river meets an ocean. The smolts turn silvery white in color, while losing their vertical stripes. In general, they swim in groups along with others and frequently visit the oceans for feeding purpose. With time, smolts body gets adjusted to saline water of the ocean. ::stage Adult:: The body marking of adult salmons is very distinctive, which differs significantly from one type to another. Based on the species in question, adults may spend anywhere around 3 - 7 years in the ocean, after which they migrate upstream to their birthplace for spawning. Adult salmons stop eating and develop different body colors; males retain bright colors, while females turn darker. After mating, the adult female lays eggs in the spawning site, and the entire journey is repeated all over again. Salmons have an average lifespan of 7 years. Most of the species inhabiting the Pacific Ocean die immediately after spawning?a behavior referred to as 'semelparity'. Very few species have the ability to spawn repeated times. Overall, the mortality rate after spawning is very high (40 percent to be precise), as adult spawners cannot spend long time in freshwater.

::stage Egg:: During fall season, salmon eggs are laid in gravel beds at the bottom of streams and lakes. Deposited several feet below the water surface, they are protected from exposure to indirect sunlight. The eggs are spherical in shape and slightly translucent with pinkish or reddish coloration. While in the egg stage, the developing organs can be seen easily through the translucent covering. Hatching usually takes place within 2 - 3 months after the eggs are laid. ::stage Alevin:: The water flow and temperature are very crucial for hatching salmon eggs. Alevins, which are 1-inch long, are characterized by presence of abnormally large eyes, attached to a bright orange sac, which is nothing, but the nutritive yolk. For nearly 3 - 4 months, the newly hatched alevins reside in the gravel nest, feeding on the yolk that hangs below their body. ::stage Fry:: The next stage is that of fry. Once the nutritive yolk is absorbed, the young fry come out of the gravel nest. The young fry swim and feed on small planktons and aquatic plants. Many times, the salmon fry become easy prey for larger fish, insects, and birds.

::stage 1:: The first stage is the egg. Unlike most other arachnids, scorpions don't lay eggs and wait for them to hatch. The eggs of a scorpion remain inside the mother's body until they are ready to hatch! After the eggs hatch, the young scorpions will crawl onto their mother's back where they'll live for quite some time. ::stage 2:: The second stage is the nymph. In this stage, they're called nymphs because they look just like a smaller version of their parents. The nymphs stay living on their mother's back until their first molt, the shedding of the outer covering of their body. After this, the nymphs go to live on their own. Nymphs will molt another five to six times before reaching full adulthood. The purpose of molting is to grow. Since scorpions have a hard outer shell, it doesn't stretch and grow with them like your skin does. So, instead scorpions have to shed it once they are too big for it. Then the next shell is soft for a little while, to allow the scorpions to grow and stretch. Once this next outer shell is too small, the scorpions shed it and do the whole process again. ::stage 3:: The third stage is the adult. In the adult stage, they are fully grown. The adults are now able to hunt and feed themselves, without the help of their parents. The adults can also mate and reproduce. | In the adult stage,it is inside its mother body | not_entailment | indicator |
