Environment:Water World

It's known that young stages tend to be surface dwellers, and therefore live in warmer water, and as they get older, they move deeper and deeper. If they're a water column species or a bottom species, there are species-specific patterns of depth utilization by these animals. We don't know if the deep-sea animals choose them or if they're just more comfortable there, or if they go someplace where it's too warm or too cold, they tend to metabolize too much or too little. But there are definitely depth-specific patterns by species of fishes in the ocean.
