*  Longtail stingray - Wikipedia
The longtail stingray reaches a maximum known disc width of 1.58 m (5.2 ft), length of 2.57 m (8.4 ft), and weight of 46.4 kg (102 lb).[1][6] It has a diamond-shaped pectoral fin disc about a sixth wider than long, with the outer corners broadly rounded. The front margins are nearly straight, meeting the tip of the snout at a blunt angle. There is a row of five papillae across the floor of the mouth; the two on the sides are smaller than the others. The pelvic fins are rounded.[7] The whip-like tail bears a stinging spine and measures more than twice as long as the disc. Behind the spine, the tail becomes laterally compressed with a low keel above and a short, narrow fin fold below.[7]. There is a row of pointed tubercles running along the midline of the back from between the "shoulders" to the base of the tail. Two much shorter rows of smaller tubercles, slightly converging backward, are found alongside the central row behind the shoulders. Numerous small dermal denticles are also found between ...

*  Snaggletooth shark - Wikipedia
The snaggletooth shark, or fossil shark (Hemipristis elongata), is a species of weasel shark, in the family Hemigaleidae, and the only extant member of the genus Hemipristis. It is found in the Indo-West Pacific, including the Red Sea, from southeast Africa to the Philippines, north to China, and south to Australia, at depths of from 1 to 130 m. This shark can be found near the bottom of the water column of coastal areas, but can be found at continental and insular shelves.[1] Its length is up to 240 cm (7.87 ft) .[2] Despite being only vulnerable to extinction, this shark is very rarely seen.. ...

*  Blotchy swellshark - Wikipedia
Like other members of its genus, when threatened the blotchy swellshark is capable of rapidly inflating its stomach with water or air. This allows the shark to wedge itself inside a rocky crevice, becoming extremely difficult to remove.[9] This species is an opportunistic, highly voracious predator; one recorded female 1 m (3.3 ft) long had 10 fish about 20 cm (7.9 in) long and 15 squid about 15 cm (5.9 in) long in her stomach. Predominantly piscivorous, this species is known to prey upon hagfish and at least 50 species of bony fishes, including fast-swimming types that inhabit open water; significant prey species include the mackerel Scomber japonicus, the sardine Sardinops melanostictus, the filefish Thamnaconus modestus, and the hakeling Physiculus japonicus. Unusually for such a small shark, it also feeds on at least 10 species of cartilaginous fishes, including lantern sharks, catsharks (particularly the cloudy catshark, Scyliorhinus torazame, and its eggs), the electric ray Narke japonica, ...
