Identification
Cleantis prismatica is a cylindrical marine isopod up to 15 mm with short antennae that typically lives in a case made of plant stems (e.g. Zostera or Posidonia) or worm tubes (e.g. of Spirobranchus). It uses its small 4th pereopods to cling on to the tube and has a rounded pleotelson which is used to close the tube end. There are three full somites on the pleotelson and a partial 4th one, and the pleon is fringed with setae.
