Pentanchidae (Deepwater catsharks)
Etymology: Halaelurus: halos (Gr.), sea; ailouros (Gr.), cat, probably an allusion to the vernacular “catshark,” so named for its cat-like eyes (See ETYFish); boesemani: In honor of Marinus Boeseman (1916-2006), curator of fishes at the Rijksmuseum van Natuurlijke Historie (Leiden, Netherlands), for his “important” contributions to ichthyology (See ETYFish).
Eponymy: Dr Marinus Boeseman (1916–2006) was a Dutch ichthyologist, working in the Department of Zoology, Rijksmuseum van Natuurlijke Histoire, Leiden, becoming Curator of Fishes (1947–1981). [...] (Ref. 128868), visit book page.

Life cycle and mating behavior
Maturidade | Reprodução | Desova | Ovos | Fecundidade | Larvas
Up to 4 egg capsules may be found in an oviduct but it is uncertain whether these hatch inside the oviduct or if the eggs are laid (Ref. 244). Live-bearing (Ref. 50449).
