The species is facing an extremely high risk of extinction in the wild. VU: Vulnerable: The species is facing a high risk of extinction in the wild. NT: Near threatened: The species does not meet any of the criteria that would categorize it as risking extinction but it is likely to do so in the future. LC: Least concern
A simple model of a system with one species each of predator and prey, the Lotka–Volterra equations, predicts population cycles. [143] However, attempts to reproduce the predictions of this model in the laboratory have often failed; for example, when the protozoan Didinium nasutum is added to a culture containing its prey, Paramecium caudatum ...

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.
Fishers have few predators besides humans. They have been trapped since the 18th century for their fur. Their pelts were in such demand that they became locally extinct in several parts of the United States in the early part of the 20th century. Conservation and protection measures have allowed the species to rebound, but their current range is ...

and Endangered Species Act: E - endangered, T - threatened XN, XE - experimental non essential or essential population E(S/A), T(S/A) - endangered or threatened due to similarity of appearance (selected only taxa found in the US, the data is current as of March 28, 2014 [2])
A chameleon successfully capturing prey with its tongue. In ecology, hunting success is the proportion of hunts initiated by a predatory organism that end in success. Hunting success is determined by a number of factors such as the features of the predator, timing, different age classes, conditions for hunting, experience, and physical capabilities.
