Frogs

Green Tree Frog

AMPHIBIA?

Frogs belong to a zoological class called Amphibia.

Amphibians, like reptiles, are cold-blooded vertebrate animals.

However, the difference between them is that amphibians lack scales and generally return to water to breed.

There are three types of Amphibians:

  • Anura or Salientia (frogs and toads)
  • Caudate (salamanders and newts)
  • Caecilians (worm-like amphibians)

Are toads and frogs the same?

Yes, toads are actually frogs!

Even so, they still have slight differences between them.

Frogs:

  • two bulging eyes
  • strong, long, webbed hind feet that are adapted for leaping and swimming
  • smooth or slimy skin
  • lay eggs in clusters

Toads:

  • stubby bodies with short hind legs
  • warty and dry skin
  • paratoid (or poison) glands behind their eyes
  • tend to lay eggs in long chains

Life cycle of a frog:

This entire cycle takes 12-16 weeks
