A Caribbean reef shark surrounded by jacks. The Caribbean reef shark feeds on a wide variety of reef-dwelling bony fishes and cephalopods, as well as some elasmobranchs such as eagle rays (Aetobatus narinari) and yellow stingrays (Urobatis jamaicensis). [1] It is attracted to low-frequency sounds, which are indicative of struggling fish. [4]
The Caribbean reef shark is up to 3 metres (10 ft) long, one of the largest apex predators in the reef ecosystem. Like the whitetip reef shark, they have been documented resting motionless on the sea bottom or inside caves - unusual behaviour for requiem sharks. Caribbean reef sharks play a major role in shaping Caribbean reef communities.
Consequently, the predators and prey will be locked in an evolutionary arms race, each looking to gain the upper hand on the other. The presence of fish predators play a large role in the size, shape and swimming performance of the Lithobates clamitans tadpoles. The presence of these predators in their habitat causes the tadpoles to develop ...
An apex predator in the Caribbean Sea was killed in an unlikely way — it got stuck in a shoe. The Caribbean reef shark was likely a month old when it died in waters off Grand Cayman, about 450 ...
The horn shark captures prey via suction, created by expanding its buccal cavity. Its labial cartilages are modified so that the mouth can form a tube, facilitating the suction force. Once the prey is drawn into the mouth, it is secured with the sharp front teeth and then ground into pieces by the flat lateral teeth.
Due to the great hammerhead shark’s immense size, it has few known predators. However, bull sharks prey upon the pups, and the adults are hunted and killed by killer whales.
In the ocean food chain, large sharks generally only have to worry about keeping orcas at bay — but a new study suggests the apex predators may have to watch out for their own.. Researchers have ...
Postural configuration of a Gray Reef Shark as it displays agonistic behaviour, in a sculpture. Agonism is a broad term which encompasses many behaviours that result from, or are triggered by biological conflict between competing organisms. [1] [2] It is defined as "survivalist animal behaviour that includes aggression, defense, and avoidance [3]".
