Which animals are dependent on the temperature of their surroundings?

Most reptiles, amphibians, fish, and insects are unable to maintain their core body temperatures from within. They are, therefore, dependent on the temperature from their surroundings.

Do all animals have the same body temperature?

Not every hot-blooded animal has the same body temperature. Humans are 98.6 degrees Fahrenheit (37 degrees Celsius), horses 100.4 degrees Fahrenheit (38 degrees Celsius), dogs 102.2 degrees Fahrenheit (39 degrees Celsius) and birds 107.6 degrees Fahrenheit (42 degrees Celsius).

How many species of reptiles are there on Earth?

There are about 10000 different species of reptiles on earth. They are cold-blooded animals belonging to the phylum Chordata of Animal kingdom. The skull of the reptiles is modified that gives the reptiles an efficient and powerful jaw action.

Can a reptile grow its tail back?

Do salamanders regenerate limbs?

In most fishes and salamanders, limited regeneration of limbs occurs, and tail regeneration takes place in larval frogs and toads (but not adults). The whole limb of a Salamander or a Triton will grow again and again after amputation. In reptiles, Chelonians, crocodiles and snakes are unable to regenerate lost parts.

Do lizards regenerate their tails?
