Shark Family Tree

Happy Chappie (Haploblepharus kistnasamyi)

Previously considered a “Natal” form of Haploblepharus edwardsii (Schinz, 1822) by Basset al. (1975) and subsequent authors, H. kistnasamyi has a colour pattern that superficially resembles, although is distinct from, that of H. edwardsii. In addition, H. kistnasamyi is distinct in having a noticeably less depressed body, which is stockier than that of H. edwardsii. This species has only been described recently (Compagno and Human 2006, Human 2006 in press).

Haploblepharus kistnasamyi is a rare shark, known only from three adult specimens (specimens tentatively identified as juveniles require confirmation), all collected from a small area, estimated to be less than 100 km², surrounding Durban, KwaZulu-Natal. It prefers shallow coastal waters, from the intertidal to 30 m depth. The apparently small population size and restricted distribution of this species makes it highly susceptible to habitat degradation, which is a major threat as intensive habitat modification and destruction is known to be occurring within its range. The species currently is known from only one location (despite adjacent waters being well-surveyed), its extent of occurrence is less than 100 km², and there is a continuing decline in the quality of its habitat, warranting an assessment of Critically Endangered B1ab(iii).
