摘要

Snailfishes are an important component of the hadal fish fauna [1].Based on osteological and other morphological characters,Kido [2] recognized the Cyclopteridae as a sister group to the Liparidae and the superfamily Cottoidea as a sister group to the two families.The close relationship between Liparidae and Cyclopteridae is also supported by the shared presence of pelvic fins that have been modified into a sucking disc [3].In addition,the results of recent studies using limited molecular data have also strongly supported a sister relationship between the Liparidae and the Cyclopteridae [4].
