Gelatinous zooplankton

From Wikipedia, the free encyclopedia

Gelatinous zooplankton is the term used to describe the fragile animals that live in the water column in the ocean. They have very delicate bodies that are easily damaged or destroyed.^[1] Gelatinous zooplankton are often transparent.^[2] All jellyfish are gelatinous zooplankton, but not all gelatinous zooplankton are jellyfish. The most commonly encountered organisms include ctenophores, medusae, salps, and Chaetognatha. However, almost all marine phyla, including Annelida, Mollusca and Arthropoda, contain gelatinous species, but those odd species usually live in the deep sea.^[3] Gelatinous zooplankton have also been called "Gelata".^[4]
