From stomach contents, the southern African frilled shark seems to feed mainly on smaller sharks such as the African sawtail catshark (Galeus polli). Its jaws, buccal cavity, and abdomen are all highly distensible, suggesting that this shark is specialized for capturing and swallowing whole large prey, with its rows of needle-like, recurved teeth preventing escape.[1] One 92 cm (36 in) long specimen was found to have swallowed a ghost catshark (Apristurus sp.) that measured 40% of its body length.
