Hydrolagus
[[Hydrolagus]] Introduction Chimaeroids are the extant members of the subclass Holocephali (living and fossil chimaeras or ratfishes) which, together with the Elasmobranchii (sharks, skates and rays), form the monophyletic class Chondrichthyes (Didier 1995; Grogan & Lund 2004; Maisey 1984, 1986;...
