The oldest known stingray taxon is "Dasyatis" speetonensis from the Hauterivian of England, whose teeth most closely resemble that of the extant sixgill stingray (Hexatrygon). Although stingray teeth are rare on sea bottoms compared to the similar shark teeth, scuba divers searching for the latter do encounter the teeth of stingrays. [6] [8]
The common stingray (Dasyatis pastinaca) is a species of stingray in the family Dasyatidae, found in the northeastern Atlantic Ocean and the Mediterranean and Black Seas. It typically inhabits sandy or muddy habitats in coastal waters shallower than 60 m (200 ft), often burying itself in sediment.
Mantas evolved from bottom-dwelling stingrays, eventually developing more wing-like pectoral fins. [8] M. birostris still has a vestigial remnant of a sting barb in the form of a caudal spine. [9] The mouths of most rays lie on the underside of the head, while in mantas, they are right at the front. [10]
For over a hundred million years, the stingray has roamed the world's oceans as an almost mythological animal: extraordinarily graceful, yet potentially lethal.
The roughtail stingray (Bathytoshia centroura) is a species of stingray in the family Dasyatidae, with separate populations in coastal waters of the northwestern and southwestern Atlantic Ocean. This bottom-dwelling species typically inhabits sandy or muddy areas with patches of invertebrate cover, at a depth of 15–50 m (49–164 ft).
Black stringrays grow to 13 feet in length, nearly 6 feet in width and can top 440 pounds, according to Fishes of Australia.. Deaths from stingray venom are rare, but the most notable example is ...
The bluespotted ribbontail ray (Taeniura lymma) is a species of stingray in the family Dasyatidae.Found from the intertidal zone to a depth of 30 m (100 ft), this species is common throughout the tropical Indian and western Pacific Oceans in nearshore, coral reef-associated habitats.
It is a bottom-dwelling species that prefers sandy or muddy habitats 1–10 m (3.3–32.8 ft) deep, and is migratory in the northern portion of its range. Typically growing to 78 cm (31 in) across, the bluntnose stingray is characterized by a rhomboid pectoral fin disc with broadly rounded outer corners and an obtuse-angled snout.
