Chimaeridae (Shortnose chimaeras or ratfishes)
Etymology: Chimaera: Named for the mythological creature composed of parts of multiple animals, referring to their odd mix of characteristics (See ETYFish); lignaria: Latin for of or belonging to wood, referring to Kevin J. Dagit, woodworker, carpenter and “supporter of research on chimaeroid fishes in his spare time” (Sharks: An Eponym Dictionary identifies Dagit [misspelled Dadit] as Didier’s son; he was, in f (See ETYFish).
Eponymy: Kevin J Dagit was, at the time of the description, the describer’s husband. [...] (Ref. 128868), visit book page.

определительные ключи | морфология | морфометрия
Purplish color. Massive head with blunt snout. Preopercular and oral lateral line canals sharing a common branch. Males with bifurcated claspers, divided for the distal 1/3 of length, purple at the base with white fleshy tips. Skin firm and not deciduous.
Males and females reach sexual maturity at 60-70 cm BDL (usually 100 cm TL) (Ref. 45044). Oviparous (Ref. 205). Eggs are encased in horny shells (Ref. 205).
