Biology
Exhibit ovoviparity (aplacental viviparity), embryos feed on yolk and ova, also consume uterine milk [733] with 2-4 young in a litter [20050] [2539]. Size at birth between 70 and 85 cm ([578] reports it at about 140 cm TL). Distinct pairing with embrace [17086].
Diet: [3667] (data: Eight males (2500-2950 mm TL), four females (1560-2960 mm TL), and six embryos (447-1201 mm TL) from the north Pacific were examined): False catsharks were found to feed predominantly on bony fishes. In north Pacific specimens, two had empty stomachs and one specimen had mud and chyme in the stomach. The others contained such varied items as sharks, bony fishes, fish skeletons and muscles, squid muscles and beaks, and octopi. The identified stomach contents included Etmopterus brachyurus, E. pusillus, Epinnula magistralis, Auxis rochei, Diodon holocanthus, Lagocephalus sceleratus, Gempylidae, Belonidae sp., and Macrouridae sp. Occurs on the continental slope (Ref. 75154).
