Most people know what turtles are. Little shell backed reptiles that often live in lakes, streams and dank vegetation. When asked what do turtles eat and drink these same people are far less knowledgeable. Turtles are kind of an exotic pet. They are not as widely understood as dogs, cats and other more common house pets.
15 of the Largest Animals in the World. The blue whale (Balaenoptera musculus) is a marine mammal belonging to the suborder of baleen whales. At 30 metres (98 ft) in length and 180 metric tons (200 short tons) or more in weight, it is the largest known animal to have ever existed.
For over a century, Paraceratherium â a 26-foot-long, 15 ton, hornless rhino â has been cited as the biggest of the big beasts. But, according to a new paper by Asier Larramendi, ancient elephants are in close competition for the title of the largest mammals to ever walk the Earth. Such contests rely on how theyâre measured, of course. Part of what makes Paraceratherium seem so large is its elongated neck.
