List of feeding behaviours

Feeding is the process by which organisms, typically animals, obtain food (animals eat a variety of food with different food behaviors. Terminology often uses either the suffixes -vore, -vory, or -vorous from Latin vorare, meaning "to devour", or -phage, -phagy, or -phagous from Greek φαγεῖν (phagein), meaning "to eat".

Evolutionary history[edit]

The evolution of feeding is varied with some feeding strategies evolving several times in independent lineages. In terrestrial vertebrates, the earliest forms were large amphibious piscivores 400 million years ago. While amphibians continued to feed on fish and later insects, reptiles began exploring two new food types, other tetrapods (carnivory), and later, plants (herbivory). Carnivory was a natural transition from insectivory for medium and large tetrapods, requiring minimal adaptation (in contrast, a complex set of adaptations was necessary for feeding on highly fibrous plant materials).[1]

parts and teeth, such as in whales, vampire bats, leeches, mosquitos, predatory animals such as felines and fishes, etc.

Mouth

Distinct forms of in birds, such as in hawks, woodpeckers, pelicans, hummingbirds, parrots, Kingfishers, etc.

beaks

Specialized and other appendages, for apprehending or killing (including fingers in primates)

claws

Changes in body colour for facilitating , disguise, setting up traps for preys, etc.

camouflage

Changes in the system, such as the system of stomachs of herbivores, commensalism and symbiosis

digestive

The specialization of organisms towards specific food sources is one of the major causes of evolution of form and function, such as:

: A form of food procurement in which food particles or small organisms are randomly strained from water.

Filter feeding

Storage behaviours[edit]

Some animals exhibit hoarding and caching behaviours in which they store or hide food for later use.
