A lizard tail shed by autotomy An autotomised skink tail exhibiting continued movement The conspicuous change in the tail pattern of this marbled gecko indicates regeneration after autotomy. Some lizards, [4] [5] salamanders [6] [7] [8] and tuatara [9] when caught by the tail will shed part of it in attempting to escape.
They are native to Indonesia (4 species) and the Philippines (1 species) where they are generally found near water, such as rivers and mangrove. [3] Sailfin lizards are semiaquatic and able to run short distances across water using both their feet and tail for support, similar to the basilisks . [ 4 ]
The ability and degree of regeneration in reptiles differs among the various species (see [111]), but the most notable and well-studied occurrence is tail-regeneration in lizards. [112] [113] [114] In addition to lizards, regeneration has been observed in the tails and maxillary bone of crocodiles and adult neurogenesis has also been noted.
Tropidophorus grayi, commonly called the spiny waterside skink, [1] Gray's keeled skink, Gray's water skink, and the Philippine spiny stream skink is a relatively abundant but secretive skink species, a lizard in the family Scincidae.
The desert grassland whiptail lizard is a relatively small reptile, whose size ranges from 2 + 3 ⁄ 4 to 5 + 1 ⁄ 4 inches (7.0 to 13.3 cm). [8] Desert grassland whiptails are very long and slim, with a thin tail that is longer than their body length. Their distinct identifying feature are the six yellowish lines that run the length of their ...
At a small tilt angle, the lift is greater for flat fish than it is for fish with narrow bodies. Narrow-bodied fish use their fins as hydrofoils while their bodies remain horizontal. In sharks, the heterocercal tail shape drives water downward, creating a counteracting upward force while thrusting the shark forward. The lift generated is ...
Marine reptiles are reptiles which have become secondarily adapted for an aquatic or semiaquatic life in a marine environment. Only about 100 of the 12,000 extant reptile species and subspecies are classed as marine reptiles, including marine iguanas , sea snakes , sea turtles and saltwater crocodiles .
A species of mudskipper (Periophthalmus gracilis)Fin and flipper locomotion occurs mostly in aquatic locomotion, and rarely in terrestrial locomotion.From the three common states of matter — gas, liquid and solid, these appendages are adapted for liquids, mostly fresh or saltwater and used in locomotion, steering and balancing of the body.
