  Elephants  Elephants are the largest existing land animals. Three living species are currently recognized: the African bush elephant, the African forest elephant, and the Asian elephant. They are an informal grouping within the proboscidean family Elephantidae. Elephantidae is the only surviving family of proboscideans; extinct members include the mastodons. Elephantidae also contains several extinct groups, including mammoths and straight-tusked elephants. African elephants have larger ears and concave backs, whereas Asian elephants have smaller ears and convex or level backs. The distinctive features of all elephants include a long proboscis called a trunk, tusks, large ear flaps, massive legs, and tough but sensitive skin. The trunk is used for breathing, bringing food and water to the mouth, and grasping objects. Tusks, which are derived from the incisor teeth, serve both as weapons and as tools for moving objects and digging. The large ear flaps assist in maintaining a ...

  Bird Birds are a group of warm-blooded vertebrates constituting the class Aves characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which evolved from forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. Birds are...

 What nutrition do dogs need?  Dogs are carnivorous, meaning the primary component of their diet should be meat. But they aren’t  obligate carnivores —or only meat-eating. In the wild, dogs survive mainly off of prey animals and some seasonal vegetables. Wild dogs will also occasionally eat fruits. When you’re deciding on your  dog’s diet , it should primarily revolve around these food items. Most dogs need some moderately-fermentable fibers in their diets.

Animal Animals are multicellular, eukaryotic organisms withinside the organic state of Animalia. With few exceptions, animals eat natural cloth , breathe oxygen, are capable of flow , can reproduce sexually, and undergo an ontogenetic degree wherein their frame includes a hole sphere of cells, the blastula, all through embryonic improvement . Over 1. five million residing animal species had been described—of which around 1 million are insects— however, it's been predicted there are over 7 million animal species in total. Animals vary in duration from to. They have complicated interactions with every different and their environments, forming complicated meal webs. The medical examination of animals is called zoology. Most residing animal species are in Bilateria, a clade whose participants have a bilaterally symmetric frame plan. The Bilateria encompass the protostomes, containing invertebrates including nematodes, arthropods, and mollusks, and the...
