Leatherback sea turtle shallower water at night (when the jellyfish rise up the water column). This hunting strategy often places turtles in very frigid waters. One individual was found actively hunting in waters that had a surface temperature of 0.4 °C. (32.72 °F). Leatherback turtles are known to pursue prey deeper than 1000 m—beyond the physiological limits of all other diving tetrapods except for beaked whales and sperm whales. Their favored breeding beaches are mainland sites facing the deep water, and they seem to avoid those sites protected by coral reefs. Adult "D. coriacea" turtles subsist almost entirely on jellyfish. Due to their
Loggerhead shrike these birds gravitate towards areas of shorter vegetation. Loggerhead shrikes have been repeatedly observed killing prey larger than themselves by spearing the neck or head of the animal and twisting. The speed at which this occurs causes a whiplash injury to the animal. The neck strength of the shrikes compensates, making their talon weakness inconsequential.

They primarily eat insects, but also consume arachnids, reptiles, amphibians, rodents, bats and small birds. The size of prey ranges from 0.001 g insects to 25 g
