Predaceous

adj. preying on other animals, hunting other creatures for food

In ecology, predation describes a biological interaction where a predator organism feeds on another living organism or organisms known as prey. Predators may or may not kill their prey prior to feeding on them. The other main category of consumption is detritivory, the consumption of dead organic material (detritus). It can at times be difficult to separate the two feeding behaviors, for example where parasitic species prey on a host organism and then lay their eggs on it for their offspring to feed on its decaying corpse. The key characteristic of predation however is the predator's direct impact on the prey population. On the other hand, detritivores simply eat what is available and have no direct impact on the 'donor' organism(s).
