زيست شناسي     واژه نامه (بعنوان مثال epibenthic)

Recorded specimens are mostly demersal, about 400-500 m deep, and associated with coral formations, where it possibly lays its egg-cases. Stomach contents consist of small invertebrates (cephalopods), small bony fishes, and one hagfish (Class Myxini) egg-case which was found in the stomach of an adult specimen. The size at first maturity is not well defined, but 45.0 cm TL males and 47.0 cm TL females are adults. Reproduction is by oviparity, with at least two amber colored egg capsules (one for each uterus) which are smooth, lacking longitudinal grooves and measuring about 15.2 cm long and 5.8 cm wide (Ref. 101269).
