The great skua is an aerial apex predator, both preying on other seabirds and bullying them for their catches. [8] Apex predators affect prey species' population dynamics and populations of other predators, both in aquatic and terrestrial ecosystems. Non-native predatory fish, for instance, have sometimes devastated formerly dominant predators.
The black seadevil family, Melanocetidae, was first proposed as a subfamily in 1878 by the American biologist Theodore Gill. [2] The only genus in the family is Melanocetus which was proposed as a monospecific genus in 1864 by the German-born British herpetologist and ichthyologist Albert Günther when he described the humpback anglerfish (M. johnsoni).

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 ...
The post Scientists just discovered a massive sea predator from the Triassic period appeared first on BGR. ... a new discovery has led them to believe that one of the largest animals was a ...
Adult sea urchins are usually well protected against most predators by their strong and sharp spines, which can be venomous in some species. [32] The small urchin clingfish lives among the spines of urchins such as Diadema ; juveniles feed on the pedicellariae and sphaeridia, adult males choose the tube feet and adult females move away to feed ...
Pleurobrachia pileus is a predator and feeds on such actively swimming prey as gammarid amphipods, crab zoeal larvae, barnacle cyprid larvae and calanoid copepods. Over much of its range it co-exists with another species of comb jelly, Bolinopsis infundibulum. The two species are found not to compete for food as their feeding habits differ.
The great hammerhead shark is an active predator with a varied diet, known prey of the great hammerhead include invertebrates such as crabs, lobsters, squid, and octopus; bony fishes such as tarpon, sardines, sea catfishes, toadfish, porgies, grunts, jacks, croakers, groupers, flatfishes, boxfishes, and porcupine fishes; and smaller sharks such ...
The leopard seal (Hydrurga leptonyx), also referred to as the sea leopard, [3] is the second largest species of seal in the Antarctic (after the southern elephant seal). Its only natural predator is the orca. [4] It feeds on a wide range of prey including cephalopods, other pinnipeds, krill, fish, and birds, particularly penguins.
