What is a reptile?

Answer 1

a crocdile is a reptile

Answer 2

Reptiles are tetrapods and amniotes, animals whose embryos are surrounded by an amniotic membrane. Today they are represented by four surviving orders:

* Crocodilia (crocodiles, caimans and alligators): 23 species
* Sphenodontia (tuataras from New Zealand): 2 species
* Squamata (lizards, snakes and amphisbaenids ("worm-lizards")): approximately 7,900 species
* Testudines (turtles): approximately 300 species

Reptiles inhabit every continent except for Antarctica, although their main distribution comprises the tropics and subtropics. Though all cellular metabolism produces some heat, most modern species of reptiles do not generate enough to maintain a constant body temperature and are thus referred to as "cold-blooded" or ectothermic (the Leatherback Sea Turtle is an exception). Instead, they rely on gathering and losing heat from the environment to regulate their internal temperature, e.g, by moving between sun and shade, or by preferential circulation — moving warmed blood into the body core, while pushing cool blood to the periphery. In their natural habitats, most species are adept at this, and can usually maintain core body temperatures within a fairly narrow range, comparable to that of mammals and birds, the two surviving groups of "warm-blooded" animals. While this lack of adequate internal heating imposes costs relative to temperature regulation through behavior, it also provides a large benefit by allowing reptiles to survive on much less food than comparably-sized mammals and birds, who burn much of their food for warmth. While warm-blooded animals move faster in general, an attacking lizard, snake or crocodile moves very quickly.

Except for a few members of the Testudines, all reptiles are covered by scales.

Most reptile species are oviparous (egg-laying). Many species of squamates, however, are capable of giving live birth. This is achieved, either through ovoviviparity (egg retention), or viviparity (babies born without use of calcified eggs). Many of the viviparous species feed their fetuses through various forms of placenta analogous to those of mammals (Pianka & Vitt, 2003 pgs: 116-118). They often provide considerable initial care for their hatchlings.

Answer 3

animals with scales and there r two types of reptiles cold blooded reptiles or animals and warm blooded reptiles or animals

Answer 4

a reptile is a cold blooded animal usually coated in scales eg snakes lizards crocodiles ect

Answer 6

a reptile is a cold blooded vertebrae with scales. eg snake lizard
crocodile alligator .

Answer 7

Heres a list of some:

Crocidiles
Caimans
Teripins
Turtles
Seaturtles
Snakes (nonvenomness and venomness)
Lizards (and Geckos)

They are all cold blooded, which means they can't provide their own body heat and must bask in the sun. All are scaley even though some you can't see or feel it.

Answer 8

bearded dragons .alligator ,tortise things with hard shells ,scales

Answer 9

cold blooded animals.

Answer 10

animals with scales, croccadiles, and alligators are.
