The prehensile-tail of a mantled howler monkey. A prehensile tail is the tail of an animal that has adapted to grasp or hold objects. [1] Fully prehensile tails can be used to hold and manipulate objects, and in particular to aid arboreal creatures in finding and eating food in the trees.
This tail is most prominent in human embryos 31–35 days old. [21] The tailbone, at the end of the spine, has lost its original function in assisting balance and mobility, though it still serves some secondary functions, such as being an attachment point for muscles, which explains why it has not degraded further.
A white-tailed deer's tail. The tail is the elongated section at the rear end of a bilaterian animal's body; in general, the term refers to a distinct, flexible appendage extending backwards from the midline of the torso. In vertebrate animals that evolved to lose their tails (e.g. frogs and hominid primates), the coccyx is the homologous ...
And because tails are an extension of the spine, the findings could also have implications for understanding malformations of the neural tube that can occur during human fetal development ...
The hands of primates are all prehensile to varying degrees; The front paws of raccoons and many of their relatives are prehensile. The feet of passerine birds can be prehensile; Tails: New World monkeys have prehensile tails; Tails of many extant lizards (geckos, chameleons, and a species of skink) are prehensile; Seahorses grip seaweed with ...
Compared to Old World monkeys, apes have more mobile shoulder joints and arms due to the dorsal position of the scapula, broad ribcages that are flatter front-to-back, a shorter, less mobile spine, and with lower vertebrae greatly reduced - resulting in tail loss in some species. [6] Prehensile tails are found in the New World atelids ...
Kinkajou using its prehensile tail Kinkajou skull Skeleton. The kinkajou has a round head, large eyes, a short, pointed snout, short limbs, and a long prehensile tail. The total head-and-body length (including the tail) is between 82 and 133 cm (32 and 52 in), and the tail measures 39 to 57 cm (15 to 22 in). [2]
