Whitefin swellshark
The whitefin swellshark (''Cephaloscyllium albipinnum'') is a little-known species of catshark, belonging to the family Scyliorhinidae, endemic to southeastern Australia. It is found down, on the outer continental shelf and upper continental slope. Reaching in length, this shark has a very thick body and a short, broad, flattened head with a large mouth. It is characterized by a dorsal color pattern of dark saddles and blotches over a brown to gray background, and light fin margins. When threatened the whitefin swellshark can inflate itself with water or air to increase its size. Reproduction is oviparous. The International Union for Conservation of Nature (IUCN) has assessed this species as Near Threatened; this catshark is a frequent bycatch of trawls, and there is evidence that its population is declining.
==Taxonomy==
Early specimens of the whitefin swellshark were often mistaken for the Australian swellshark (''C. laticeps'') or the draughtsboard shark (''C. isabellum''). In 1994, it was identified as a new species and known provisionally as ''Cephaloscyllium'' "sp. A", until it was formally described by Peter Last, Hiroyuki Motomura, and William White, in a 2008 Commonwealth Scientific and Industrial Research Organisation (CSIRO) publication.〔 Its specific epithet ''albipinnum'' comes from the Latin ''albi'' meaning "white", and ''pinna'' meaning "fin", referring to its distinctive white fin margins. The type specimen is a long adult male caught near Maria Island, Tasmania.〔
