Male sockeye salmon (Oncorhynchus nerka) during spawning. The sockeye salmon hatches in rivers in Canada and Alaska,USA. It spends the first few years of its life living there,before moving into the Pacific Ocean,where it stays for around three years. It then begins a migration back to the river in which it was born,and may cover thousands of kilometres. It locates its river using its excellent sense of smell. The male develops a red coloration and powerful jaws with which to fight other males during spawning. These efforts leave most males dead after spawning | |
