Do all mammals have 2 or 4 legs?
Almost all mammals have four limbs. The big exceptions would be the cetaceans (whales and dolphins) and the sirenia (manatees and dugongs). Both groups have become completely aquatic and have either lost their hindlimbs entirely, or have reduced them to small internal vestigial organs.
How many legs are there in mammals?
The basic body type is quadruped, and most mammals use their four extremities for terrestrial locomotion; but in some, the extremities are adapted for life at sea, in the air, in trees, underground, or on two legs.
Are all mammals 4 legs?

A biped is an animal that walks on two legs, with two feet. Human beings are one example of bipeds. Most animals are not bipeds, but mammals that are include kangaroos and some primates. The ostrich, a giant, flightless bird, is the fastest living biped, and animals like bears and lizards are occasional bipeds.
How many legs are of an animal?
That seems like a lot of two-legged animals, but non-human mammals number around 500 billion and almost all of them are four-legged. And according to some studies, there might be another 10 trillion reptiles and amphibians. So the mean number of legs for land vertebrates is very close to 4 (it's actually about 3.96).

Do any animals have 3 legs?
Apart from the parrot conjecture, there are no known species where three legs are standard, although the movement of some macropods such as kangaroos, which can alternate between resting their weight on their muscular tails and their two hind legs and hop on all three, may be an example of tripedal locomotion in ...
Do any animals have 10 legs?
