Features

Hemiscyllium Halmahera is similar to that known from the Cenderawasih Bay in the northwest of the island of New Guinea in the Indonesian province of Papua Hemiscyllium galei and differs from this species mainly by the coloring. The shark is brownish in color and shows a pattern of numerous, composed of two to three dark, polygonal points spots, widely scattered white dots between these spots, a few (<10 mm) dark spots on the top of the head and paired dark markings on the head base. On the back there show some large, U-shaped, dark spots, which are outlined in more or less distinctly white in their lower halves. Among them are vertical rows of two to three dark spots.

The distribution area is located in the waters around the Moluccas.

The shark is nocturnal and puts many routes to its paired fins running back. He can survive an hour in oxygen-poor water.

Galei Hemiscyllium other hand has 7-8 large, horizontally oriented, elongated, dark spots on the underside between the fuselage and tail fin base and usually 25 dark spots on the top of the head.
