From Pathfinder Wiki
Small crustaceans serve several important roles. They are often the first level of consumers in trophic webs, eating algae and phytoplankton, or serving as scavengers eating detritus and other decaying and waste material. As such, they are a critical component in keeping marine environments clean. But small crustaceans are also a very important component of the food webs as a source of nourishment for progressively larger animals, and crustaceans are among the most abundant organisms in numbers and weight in marine environments.
