Shark Family Tree

Plain Happy (Haploblepharus fuscus)

Haploblepharus fuscus prefers inshore rocky reef habitats. All specimens examined by Human (2003, 2007) were collected very close to shore (rock and surf angling), with no records of specimens being caught by offshore fishing activities.


Very little of the life history is known for H. fuscus. Maximum size is reported at 73 cm total length (TL) (Compagno 1984). Males are juvenile at 43.8-46.0 cm TL, adolescent at 49.5-54.3 cm TL, and mature at 55.0-64.9 cm TL. Females are adolescent at 49.6-56.8 cm TL, and mature at 60.9-63.1 cm TL. The juveniles of this species are scarce and there appears to be an unknown habitat that is used by H. fuscus for egg laying, and where juveniles spend that stage of their life history (Human 2003, 2007). Other members of this genus produce a single eggcase per uterus which is assumed here for this species.
