A uniped (from Latin uni-"one" and ped-"foot") is a person or creature with only one foot and one leg, as contrasted with a biped (two legs) and a quadruped (four legs). Moving using only one leg is known as unipedal movement. Many bivalvia and nearly all gastropoda molluscs have evolved only one foot.
This condition has been called zygodactyly or didactyly, but the specific arrangement in chameleons does not fit either definition. The feet of the front limbs in chameleons, for instance, are organized into a medial bundle of digits 1, 2 and 3, and a lateral bundle of digits 4 and 5, while the feet of the hind limbs are organized into a medial ...
Some birds, like the sanderling, have only the forward-facing toes; these are called tridactyl feet while the ostrich have only two toes (didactyl feet). [2] [4] The first digit, called the hallux, is homologous to the human big toe. [7] [10] The claws are located on the extreme phalanx of each toe. [4] They consist of a horny keratinous ...

Two new studies indicate the importance of getting a good night's sleep — with one study saying a lack of sleep may be sabotaging the brain’s ability to keep intrusive thoughts at bay.
Sloths move incredibly slowly, traveling around 125 feet through the treetops in one day. When on the ground, they’re even slower and crawl about one foot per minute. If a sloth were to sprint ...
