Balloon shark
The balloon shark (''Cephaloscyllium sufflans'') is a species of catshark, and part of the family Scyliorhinidae, endemic to the southwestern Indian Ocean off South Africa and Mozambique. Benthic in nature, it is found over sandy and muddy flats at depths of . This thick-bodied species has a broad, flattened head and a short tail; its distinguishing traits include narrow, lobe-like skin flaps in front of the nostrils, and a dorsal color pattern of faint darker saddles on a light grayish background.
Befitting its common name, the balloon shark can inflate itself with water or air as a defense against predators. It feeds on a variety of crustaceans, cephalopods, and fishes. Reproduction is oviparous, with females producing egg cases two at a time. This species is caught incidentally in bottom trawls but does not seem to be threatened by fishing pressure, hence its assessment as Least Concern by the International Union for Conservation of Nature (IUCN).
==Taxonomy==
British ichthyologist Charles Tate Regan described the balloon shark as ''Scyliorhinus sufflans'' in a 1921 issue of the scientific journal ''Annals and Magazine of Natural History''. He placed the species within the subgenus ''Cephaloscyllium'', which later authors have elevated to the rank of full genus. The type specimen measures long and was collected away from the mouth of the Umvoti River in South Africa.
