Rock pythons are bulk feeders, and may eat prey as large as gazelles.

Feeding is the process by which organisms, typically animals, obtain food. There are many types of feeding that animals exhibit, including:

filter feeding - obtaining food suspended in the water column
deposit feeding - obtaining food particles in soil
fluid feeding - obtaining food by consuming other organisms fluids
bulk feeding - obtaining food by eating pieces of other organisms or swallowing them whole
phagocytosis - engulfing food with cell membrane

Another classification refers to the food groups some animals specialize in, such as:

There are also several food sources which have caused the development of specialized feeding behaviors, such as:

Ophiophagy: feeding on snakes
Hematophagy: feeding on blood
Coprophagy: feeding on faeces
Cannibalism: feeding on members of the same species
Trophallaxis: regurgitation of food to another animal
Paedophagy: feeding on the young of other species
Lepidophagy: of fish, feeding on the scales of other fish

In many instances, the specialization of organisms in a specific type of food source has been one of the major causes of evolution of form and function, such as:

Many different forms of beaks in birds have evolved in function of feeding sources

mouth parts and teeth, such as in whales, vampire bats, leeches, mosquitos, predatory animals such as felines and fishes, etc
distinct forms of beaks in birds, such as in hawks, woodpeckers, pelicans, hummingbirds, parrots, kingfishers, etc.
specialized claws and other appendages, for apprehending or killing (including fingers in primates
changes in body colour for facilitating camouflage, disguise, setting up traps for preys, etc.
changes in the digestive system, such as the system of stomachs of herbivores, commensalism and symbiosis
