The Triton epaulette shark (Hemiscyllium henryi) is a
Morphology
These small slender sharks are characterized by nasoral and perioral grooves, short barbels, a small transverse mouth below the eyes, two similar-sized dorsal fins and long slender tail. They are typically pale gray-brown with a white
The lack of small dark spots on their dorsal fins sets them apart from other Hemiscylliidae. The males and the unsexed sharks grow to an average of 78.3 cm in length. The females grow to an average of 81.5 cm in length. In three preserved specimens collected in the Triton Bay region, the number of vertebrae was found to range from 191 to 194.[3]

Etymology
The shark is named in honor of underwater photographer Wolcott Henry, who has supported Conservation International's marine initiatives, which includes the taxonomy of western New Guinea fishes.[6]
Distribution
H. henryi have been observed and collected from western New Guinea (West Papua Province, Indonesia) in the southern Bird's Head region. They were also observed at Triton Bay and Selat Iris, a narrow channel between the mainland and Aiduma Island and near the southwestern tip of the Bomberai Peninsula - 135 km west of Triton Bay. Further surveys may show that H. Henryi have a broader range in southern West Papua.[7]
Conservation status
This species was recently described in 2008 and their conservation status is listed as vulnerable by the IUCN. Due to their limited range H. henryi would be extremely susceptible to depletion should attempts be made to harvest them for trade or food.[7]
Relationship with humans
Bamboo sharks are not dangerous to humans. Additionally, bamboo sharks are one of the few species of sharks kept in home aquariums.[8]
