Biology
Oviparous, paired eggs are laid. Embryos feed solely on yolk [733]. Sexual dimorphism is evident in dentition of males (Ref. 49562). Males have longer teeth with fewer cusps (Ref. 51093) to make "quot;courtship biting"quot; more effective (Ref. 49562).

bathydemersal; marine; depth range 700 - 1500 m [13336]
