Nelocira swainsoniiEurydice swainsoniiConilera grampoidesCirolana borealis[2] Cirolana cranchii is a species of isopod crustacean.

Cirolana cranchii was described by the English zoologist William Elford Leach in 1818; he named the genus anagrammatically after an unknown woman called Caroline/Carolina, and the species after his friend and collector John Cranch.

[6] Bruce and Ellis consider only the eastern North Atlantic and Mediterranean records reliable.

The body consists of 11 visible segments each covered in a smooth dorsal scale behind the head, with a triangular tail (pleotelson).

The female has a wider pleotelson and non-angled uropods, and lacks the dense bristles (setae) on these parts.
