Hammerhead sharks eat a large range of prey such as fish (including other sharks), squid, octopus, and crustaceans. Stingrays are a particular favorite, with the positioning of their (comparatively) smaller, crescent-shaped mouths underneath their T-shaped heads allowing for skilled skate, ray, and flounder hunting, among other seafloor ...
Researchers believe great hammerhead sharks are cannibalistic and sometimes eat their own young. Great hammerhead sharks love to eat stingrays and have been found with their stingers protruding ...
All sharks and rays are cartilaginous fish, contrasting with bony fishes. Many rays are adapted for feeding on the bottom. Many rays are adapted for feeding on the bottom. Guitarfishes are somewhat between sharks and rays, displaying characteristics of both (though they are classified as rays).
Great hammerheads are apex predators among sharks, and are specialists at feeding on other sharks, rays, and skates, especially stingrays. [18] The venomous spines of stingrays are frequently found lodged inside its mouth and do not seem to bother the shark, as one specimen caught off Florida had 96 spines in and around its mouth.
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]
Nurse sharks are opportunistic predators that feed primarily on small fish (e.g. stingrays) and some invertebrates (e.g. crustaceans, molluscs, tunicates). [11] They are typically solitary nocturnal animals, rifling through bottom sediments in search of food at night, but are often gregarious during the day forming large sedentary groups.
Dr. Jared Ross, an emergency room physician and a former lifeguard and rescue scuba diver, tells Yahoo Life that stingrays are typically encountered in warm, shallow water and tend to burrow in ...
They have also been known to eat stingrays, cuttlefish, squid, and octopus. [2] Groups of spinner sharks are often found pursuing schools of prey at high speed. [11] Individual prey are seized and swallowed whole, as this shark lacks cutting dentition. [10]
