Description
editThis slender wish grows up to 30 cm (12 in) long. It is pale brown with small brown spots and blotches, with paler sections in between. This colouration allows it to blend into the sea floor. As with other tonguefishes, the eyes are both on the left side of the body.[1]
Similar species
editThis species may be confused with Cynoglossus zanzibarensis, which has red spots on the dorsal and anal fins.
Distribution and habitat
editIt is commonly found in southeastern Atlantic Ocean off the south western coast of Africa from the Cunene River to the Cape of Good Hope. It is normally found at depths of no greater than 100 m (330 ft), but it has also been reported on the continental slope.[2] It has been recorded at depths of up to 450 m (1,480 ft).[3] It is most common in areas where the sea floor is covered in fine sand or mud.[1]
Ecology
editThe sand tonguefish feeds on benthic invertebrates.[1] It is known to be an important prey species for the cape fur seal around Plettenberg Bay.[4]
Fisheries
editThis species is targeted by sole fisheries, as well as being caught as bycatch by other demersal trawl fisheries.[3][4]
Conservation
editThis species is currently listed as being data deficient by the IUCN.[3]
