All of these plant-eating animals lack the enzyme cellulase, which is capable of breaking down the tough cellulose in plant cell walls. The stomach of these grazing herbivores consists of four chambers—the rumen, the reticulum, the omasum, and the abomasum—each playing different roles in the digestion process.
The ruminant animal swallows its food rapidly without chewing, and later regurgitates it brings it back up into the mouth , then masticates it chews , and finally re-swallows it. When grazing, ruminants swallow their food rapidly, sending large amounts into the largest chamber of the stomach, the rumen, where it is stored and partly digested before regurgitation and chewing when the animal is resting.
Rumination is an adaption by which herbivores can spend as little time as possible feeding when they are most vulnerable to predation and then later digest their food in safer surroundings. The myth may arise from the existence of calculi, mineral deposits similar to kidney stones, in the bodies of some snakes, Scher says. It involves contraction of the intestines, followed by retching and then the grand exit.
Snakes vomit for the same reasons other animals do—including nerves. This python vomited an entire antelope likely due to feeling stressed around nosy humans. Most cat owners deal with hairballs, lovely little packets of matted hair deposited by their pet felines.
Hairballs happen when fur gets built up in their gastrointestinal tract, setting off receptors that tell the brain to vomit, says Mark Rondeau of the University of Pennsylvania College of Veterinary Medicine. Regurgitation is a more passive, reflexive process, often brought on by an irritation of the esophagus, he adds. Birds of prey , such as owls and hawks, "regurgitate a pellet or casting of the undigested bone, fur, and feathers" of prey on a daily basis," Kim Stroud, director of the California-based Ojai Raptor Center , says by email.
Why they like to slide around in undigested hoof, bone, and hair is unclear, she says. Some vultures, such as the turkey vulture, vomit as a defense , stinging potential predators with their acidic puke and lightening their own load so they can fly away more easily.
European roller nestlings also produce a gooey orange vomit that deters predators. When attacked, large white butterfly caterpillars throw up a green fluid of semi-digested cabbage, which already contains compounds that smell and taste unpleasant to predators, such as birds.

Most ruminants belong to the family of bovids, Bovidae. Within that group we find the subfamily of bovines or Bovinae, which includes cattle.
These are probably the best known ruminant animals. Below is a list of some bovine animals:. Did you know Camelids are not considered ruminants as they do not have a glandular fore stomach. Learn more in our article about the differences between camels and dromedaries. Also within the family of the bovids we can find the subfamily Caprinae, the goat-antelopes. Within that subfamily we find the genus Ovis , the ovines or sheep. The second largest group of ruminants are the ovines, ruminant animals best-known and appreciated for their milk and wool.
There are not as many different types as there are in the cattle group but we can still give you a considerable list of ovine animals:. There are many different subspecies of domestic and wild sheep, and most of them are named for their native region and habitat.
Despite being closely related and belonging to the same subfamily, goats and sheep underwent a phylogenetic separation. That happened in the last stage of the Neogene period, which started 23 million years ago and finished only 2.
In geological time, that's only yesterday! The third group of ruminant animals we examine is that of goat-antelopes, or caprines. The subfamily Caprinae is a cousin to the Bovinae, as they both belong to the Bovidae family.
Within this subfamily you can find the ovids, which we separated so as not to mix up goats and sheep. Through remastication, ruminants are able to reduce the particle size of their food to ensure that their body can assimilate and digest it. To complete our full list of ruminant animals, we will now look at a very beautiful and noble group of ruminants: Deer.
