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.
Calling this competition doesnât interest me, though. Whether a rhino or elephant was the largest land mammal of all time isnât especially important. Whatâs curious is that there isnât a clear winner between the two lineages. (There canât be until better skeletal material gives us more precise dimensions for these giants.) Just as with the largest dinosaurs, the most superlative mammals of all time seem to cluster around a similar body size.
