Reticulate Swellshark

About the Reticulate Swellshark

Reticulate swellsharks can be found off the coast of northwestern Australia, in the eastern Indian Ocean, at depths of 290 to 420 m (951–1,378 ft).

Biology and Behaviour

Reticulate swellsharks are small, but have a stocky build with a short, wide head and a sizeable mouth. They have a pattern of dark brown lines that trace a series of hollow saddles and narrow rings on a light background along their back. Like other swellsharks, Reticulate swellsharks also inflate their bodies when threatened.

Reproduction

Little is known about the reproduction of Reticulate swellsharks, other than they are oviparous. This means that they lay eggs in which embryos develop and feed on yolk. The size at birth is thought to be less than 13 cm (5.12 in). Males mature at approximately 46 cm (18.1 in), while the species reaches at least 52 cm (20.5 in) in total length.

Conservation

The IUCN lists Reticulate swellsharks as Least Concern. The species has no commercial value and is probably released when caught as bycatch. Parts of its range are protected within the North-west Marine Parks Network, providing refuge for the species.

There are currently no species-specific conservation measures in place. Further research is needed on the species’ population size, biology, life history, and population trends.
