Mystacocarida

From open-encyclopedia.com - the free encyclopedia.

Mystacocarida are interstitial Crustaceans, part of the Meiobenthos. Their taxonomy is extremely conservative, superficially all mystacocarids look alike. There are only 12 described species divided between two genera, Derocheilocaris and Ctenocheilocharis.

South American Mystacocarida

This mystacocarid was found in the zone of retention at Playa Ritoque in Region V, Chile (pictured below). All the Mystacocarida from South America reported sofar have been of the genus Ctenocheilocaris (Hessler,1988)so it is assumed that this is the genus of the individual pictured above. Mystacocarida have been observed in samples from Playa Grande (Las Cruces) and Curiñanco (near Valdivia). Zinn et al.(1982)give a bibliography for the Mystacocarida.
