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.

Short description Bestämningsnycklar | Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt) : 0; Taggstrålar i analfenan: 0. Dark spots small and very numerous, usually not larger than spiracles, over or between weak saddles or bars (Ref. 11146).

A little-known but wide-ranging bottom-dwelling shark found on continental and insular shelves (Ref. 11146). Probably caught with bottom trawls (Ref. 30573). Live-bearing (Ref. 50449).

Life cycle and mating behavior Könsmognad | Reproduktion | Lek | Ägg | Fecundity | Larver

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).
