Commensalism is a long-term biological interaction in which members of one species gain benefits while those of the other species neither benefit nor are harmed. [1] This is in contrast with mutualism , in which both organisms benefit from each other; amensalism , where one is harmed while the other is unaffected; and parasitism , where one is ...
Vultures are scavengers, meaning that they eat dead animals. Outside of the oceans, vultures are the only known obligate scavengers. [20] They rarely attack healthy animals, but may kill the wounded or sick. When a carcass has too thick a hide for its beak to open, it waits for a larger scavenger to eat first. [21]
The term raptor is derived from the Latin word rapio, meaning "to seize or take by force". [8] The common names for various birds of prey are based on structure, but many of the traditional names do not reflect the evolutionary relationships between the groups.

Outcrossing can be a useful technique in animal breeding.The outcrossing breeder intends to remove the traits by using "new blood." With dominant traits, one can still see the expression of the traits and can remove those traits, whether one outcrosses, line breeds or inbreeds.
Additionally, this term is also used in paleobiology to describe taxa of animals which have an increased slicing component of their dentition relative to the grinding component. [2] In domestic settings, e.g. cats may have a diet designed from only plant and synthetic sources using modern processing methods. [ 3 ]
Obligate anaerobe, an organism that cannot survive in the presence of oxygen; Obligate air-breather, a term used in fish physiology to describe those that respire entirely from the atmosphere; Obligate biped, Bipedalism designed to walk on two legs; Obligate carnivore, an organism dependent for survival on a diet of animal flesh.
Animals are described as 'obligate necrophages' if they use carrion as their sole or main food source and depend on carrion for survival or reproduction. [4] The term 'specialists' is also sometimes used in recognition that these animals have traits favoring necrophagy and making other feeding beahviors difficult. [ 14 ]
