In Gadus the two component muscle insertions to the base of the caudal rays is clearly marked and appears no different from the arrangement of depressores and erectores muscle of the dorsal and anal fin rays. Muraenolepis exhibits a simplified system of caudal fin musculature in that no separate terminal segment arising from the hypural plate is differentiated. 'Interradialis' muscles interconnect the posterior 22nd dorsal and 'caudal' rays and the posterior 18 anal rays (dorsal and anal ray numbers counted forward from the median caudal ray)..
