In [[crustacean]]s, the carapace functions as a protective cover over the [[cephalothorax]] (i.e., the fused head and [[thorax]], as distinct from the [[abdomen]] behind). Where it projects forward beyond the eyes, this projection is called a [[rostrum (anatomy)|rostrum]]. The carapace is [[Calcification|calcified]] to varying degrees in different crustaceans.<ref>{{Cite web |editor-last=Pentcheff |editor-first=Dean |title=Carapace |url=http://atiniui.nhm.org/glossary/define.html?term=Carapace |access-date=17 June 2012 |website=Crustacea Glossary |publisher=[[Natural History Museum of Los Angeles County]] |archive-date=23 September 2013 |archive-url=https://web.archive.org/web/20130923035009/http://atiniui.nhm.org/glossary/define.html?term=Carapace |url-status=dead }}</ref>

[[Zooplankton]] within the phylum Crustacea also have a carapace. These include [[Cladocera]], [[ostracod]]s, and [[Isopoda|isopods]], but isopods only have a developed "cephalic shield" carapace covering the head.
