Henry’s Epaulette Shark (Hemiscyllium henryi) is a newly (2008) described species, which is known from very few specimens that are highly restricted geographically. The distribution and occurrence of Henry’s Epaulette Shark is not adequately known at this stage and there is insufficient information currently available on any potential threats. Further information is required to assess whether there is any conservation concern. Some threats are suspected (fishing pressure in shallow inshore environments can be significant in eastern Indonesia and includes illegal fishing, dynamite fishing and trawling) and although there may be some refuge in protected and remote areas, details on the level of threats are not available. An overall lack of information means that this species cannot be listed beyond Data Deficient at present. Surveys and research into biology and threatening processes are a priority to accurately assess the status of this species.
Little is known about the population size of Henry's Epaulette Shark and no scientific data are currently available.
Other locations where this species may possibly occur (Bomberai and Fakfak Peninsulas) are remote areas with little human activity (G. Allen pers. comm. 2011). However, fishing pressure in shallow inshore environments, including coral reefs where this species is found can be significant in eastern Indonesia, and includes illegal fishing, dynamite fishing and trawling which may affect this species through habitat destruction and capture as bycatch (Kyne and Heupel 2011).
There are no current conservation processes in place for Henry's Epaulette Shark. Triton Bay where Henry’s Epaulette Shark has been observed is a marine reserve. This species needs scientific investigation into its biology, ecology, distribution and demography, as well as threats, in order to assess what conservation measures may be needed.
Hemiscyllium henryi (Triton epaulette shark or Henry's epaulette shark) is a species of bamboo shark in the family Hemiscylliidae. Together with H. galei, it was only scientifically described in 2008. At present, H. henryi is only known from depths of 3 to 30 metres (9.8 to 98.4 ft) at reefs near Triton Bay on the southern coast of West Papua, Indonesia. It reaches a length of 81.5 centimetres (32.1 in), and is covered in numerous fine black spots. It has large, "double" spot on the side behind the pectoral fins.
