bottomfeeder

A bottomfeeder is an organism that feeds on detritus or sediment at the bottom of a body of water. These organisms are often scavengers, consuming dead organic matter that has sunk from higher levels of the water column. This diet can include decaying plants, animal remains, and waste products.

Bottomfeeding is a common feeding strategy in many aquatic environments, from shallow lakes and rivers to the deep sea. Organisms that employ this method have adapted to living and foraging in the benthic zone. Their physical characteristics can vary widely depending on the specific species and habitat. Some bottomfeeders, like certain types of fish, may have specialized mouths or sensory organs to locate food in murky or dark conditions. Others, like many invertebrates, may filter food particles from the sediment or actively sift through it.

Examples of bottomfeeders include various species of fish such as catfish and sturgeon, as well as invertebrates like sea cucumbers, mussels, clams, and many types of worms. These organisms play an important role in aquatic ecosystems by helping to break down organic matter and recycle nutrients. This process contributes to the overall health and productivity of the environment. The term "bottomfeeder" can also be used metaphorically to describe a person or organization that engages in low-level or disreputable activities.
