treeseed commented on the word rainbow trout
The rainbow trout (Oncorhynchus mykiss)is a species of salmonid native to tributaries of the Pacific Ocean in Asia and North America as well as much of the central, western, eastern, and especially the northern portions of the United States. The rainbow trout are unusual in that there are two forms which sometimes share the same habitat. The anadromous form called "steelhead" migrate to the ocean, though they must return to fresh water to reproduce.
The freshwater form is called "rainbow trout", based on the broad red band along their sides. Steelhead are exactly the same species as rainbow trout. However, the difference is anadromy. After going to sea, their color changes, including loss of the red band. They stay at sea for 1-4 years, and return to fresh water to spawn. Rainbows stay in fresh water their whole lives.
