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).

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).
