Sea cucumbers are echinoderms from the class Holothuroidea ( HOL-ə-thyuu-ROY-dee-ə, HOH-lə-). They are benthic marine animals found on the sea floor worldwide, and the number of known holothuroid species worldwide is about 1,786, with the greatest number being in the Asia–Pacific region. Sea cucumbers serve a useful role in the marine ecosystem as detritivores who help recycle nutrients, breaking down detritus and other organic matter, after which microbes can continue the decomposition process. Sea cucumbers have a leathery skin and an elongated body containing a single, branched gonad; they are named for their overall resemblance to the fruit of the cucumber plant. Like all echinoderms, s…

In biology, detritus ( or ) is organic matter made up of the decomposing remains of organisms and plant material, and also of feces. Detritus usually hosts communities of microorganisms that colonize and decompose (remineralise) it. Such microorganisms may be decomposers, detritivores, or coprophages. In terrestrial ecosystems detritus is present as plant litter and other organic matter that is intermixed with soil, known as soil organic matter. The detritus of freshwater ecosystems are mostly leaf litter and other decaying organic materials. These are decomposed by microbes, and small invertebrates that shred leaves or filter feed suspended organic matter. The detritus of marine ecosystems…

A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. Most coral reefs are built from stony corals, whose polyps cluster in groups. Coral belongs to the class Anthozoa in the animal phylum Cnidaria, which includes sea anemones and jellyfish. Unlike sea anemones, corals secrete hard carbonate exoskeletons that support and protect the coral. Most reefs grow best in warm, shallow, clear, sunny, and agitated water. Coral reefs first appeared 485 million years ago, at the dawn of the Early Ordovician, displacing the microbial and sponge reefs of the Cambrian. Sometimes called rainforests of…
