[1] They occupy the sea floors and lake beds, which usually consist of mud, sand, gravel or rocks. [1] In coastal waters, they are found on or near the continental shelf, and in deep waters, they are found on or near the ...
A school of large pelagic predator fish (bluefin trevally) sizing up a school of small pelagic prey fish (). Pelagic fish live in the pelagic zone of ocean or lake waters—being neither close to the bottom nor near the shore—in contrast with demersal fish that live on or near the bottom, and reef fish that are associated with coral reefs.
The fish had already died at the time of the discovery, and was found near the shores of La Jolla Cove. Because the fish usually reside in the deep ocean, they are only spotted close to the ...
