The shrew has to eat almost constantly, because they can only survive a few hours without food. Their metabolism drops when they are at rest.
Animals have very few needs based on their instincts: food, procreation. Food means survival to most species. Wild species in particular. Even with the security of being a pet in a home with caring families, animals, domesticated animals, also have an instinct to obtain food.
Although dogs may seem perpetually interested in food, an excessive appetite (called polyphagia or hyperphagia) may signal a more serious issue that should be examined by a veterinarian.
Self-cannibalism behavior has been documented in North American rat snakes: one captive snake attempted to consume itself twice, dying in the second attempt. Another wild rat snake was found having swallowed about two-thirds of its body.
Snakes, frogs, and lizards, for example, do not chew their food before swallowing it. They swallow what they eat immediately from their jaws. A snake has the ability to consume larger animals. Such animals lack teeth for biting and chewing.
Tardigrades can live years without food. These are their adaptations to extreme climatic conditions in their habitat for survival. Animals like Emperor penguin, Tardigrade do not eat food in extreme climatic conditions and undergoes a dormant stage.
#1 Fat Animal: Blue Whale
The appetite of the blue whale is notorious. Daily, it consumes more than 4 tons of krill. In order to meet their demand for food, this animal which is the largest in the world takes big gulps of water. Then, it strains the water out using its unique baleen plates as a strainer.
The larva of the polyphemus moth of North America holds the record for being the greediest animal. It consumes an amount equal to 86,000 times its own birthweight in the first 56 days of its life. In human terms, it would be like 7 lb baby taking in 273 tons of nourishment.
The koala holds the accolade for 'the animal that sleeps the most'. This Australian icon sleeps for 20-22 hours each day (sounds good to us), making it the sleepiest creature in the animal kingdom.
Many species of animals certainly do overeat, for various reasons. A male lion can eat as much as ninety pounds in one feeding. For an average-sized lion, that's about twenty percent of his body weight! The lion gorges himself because he may not get another hunting and feeding frenzy for another several days or weeks.
Do we really need a reminder to eat breakfast, lunch, and dinner? Apparently so. While our society may have evolved to provide us with endless opportunities to eat, our bodies are primarily concerned with keeping the well-oiled machine going. This means that we start to feel hungry once our stomach is empty.
Some animals can be free-fed and will stop eating when they are full, while others will gain weight with just the occasional table scrap. Similar to people, some of this is genetic and some is environmental.
Because of the food they eat, and the small number of nutrients and energy they get from that food, Koalas spend most of their time sleeping after eating. You could probably say that all koalas do is eat and sleep!

Sloth. When people think of the word "lazy", sloths are often one of the first animals to come to mind, and it's not surprising. They sleep for up to 20 hours a day and are known for being extremely slow-moving.
Evolutionary biologists determined that an animal's behaviors are altruistic when they benefit other individuals, even to the potential detriment of themselves. Species with complex social structures like bees, ants and termites provide great examples of biological altruism.
A new study finds that unlike humans, Chimpanzees are entirely selfish creatures who act in their own interests, turning conceived wisdom on its head.
CHIMPANZEES. RECKONED to be the most-intelligent animals on the planet, chimps can manipulate the environment and their surroundings to help themselves and their community. They can work out how to use things as tools to get things done faster, and they have outsmarted people many a time.
