Coho salmon have dark metallic blue or greenish backs with silver sides and a red light belly and there are small black spots on the back and upper lobe of the tail whiThis species look like a fish with red color on its body. Coho Salmon always eats plankton ,insects and switches to a diet of small fish as adults in the ocean. They reproduce in inland rivers. Coho salmon adults migrate from a marine environment to fresh water streams and rivers of their birth in order to reproduce their babies. The adult fish will die after bearing their babies. After the babies are born, they will migrate to a marine environment and keep the cycle. When the baby coho salmons are going to migrate to the sea, they will lose their parr marks, a pattern of vertical bars and spots useful for camouflage, and gain the dark back and light belly coloration used by fish living in open water. When they are spawning their children, the females fish will prepare nests where the eggs will remain for six to seven weeks until they hatch.

Their current range is at central CA coast in U.S. California and open waters. They live in the ocean, but when they reproduce, they will swim back to the rivers of U.S.A (CA) where they from. Coho Salmon are migratory fish, they will leave the place where they born to the ocean, then come back to rivers when they are going to reproduce. They live in the water, so it is below ground. Coho Salmon feed on plankton ,insects and switches to a diet of small fish as adults in the ocean.
 * Habitat:**

Coho Salmon is endangered because of humans' dam. The dam blocked the way that Coho Salmon will pass through it back to their birth placement. Coho Salmon will die before it get to the birth place to reproduce because dam block their way totally.
 * Problem:**

We raised Salmon Endangered Species Act (ESA) recovery plan, which is underway throughout the entire Northwest region. Also, we are trying to build captive-rearing in hatcheries, removal and modification of dams that blocks salmon migration and improve water quality to help the Coho Salmon.
