Tóm tắt
Taxonomically important aspects of the anatomy of the common eolid nudibranch,Cratena pilata, are presented. The uniserate radula possesses a prominent central cusp and 4 to 7 lateral cusps. Up to 60% of radular teeth may be asymmetric. The triangular, slightly emarginate jaws are described and figured. The genitalia are of the facelinid type and are described. The penis is unarmed. On the basis of anatomy, this species is a member of the Favorinidae (Favorininae). Proper generic placement isCratena Bergh, 1864, a favorinid; notCratena Bergh (1885), a cuthonid.
