Amphibians are classed into three orders:
- The Anura, which includes frogs and toads
- The Caudata, which includes salamanders and newts
- And the Gymnophiona, which includes caecilians (limbless, worm-like creatures)
All three of these groups are characterised by being reliant on water and ectothermic (cold-blooded).
Unfortunately, approximately 40% of all amphibians are in direct danger of extinction.
