The largest living amphibian is the 1.8 m (5 ft 11 in) South China giant salamander (Andrias sligoi), but this is dwarfed by prehistoric temnospondyls such as Mastodonsaurus which could reach up to 6 m (20 ft) in length. [7] The study of amphibians is called batrachology, while the study of both reptiles and amphibians is called herpetology.
Amphibians are ectothermic, anamniotic, four-limbed vertebrate animals that constitute the class Amphibia. In its broadest sense, it is a paraphyletic group encompassing all tetrapods excluding the amniotes (tetrapods with an amniotic membrane , such as modern reptiles , birds and mammals ).
All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this.

Amphipoda (/ æ m ˈ f ɪ p ə d ə /) is an order of malacostracan crustaceans with no carapace and generally with laterally compressed bodies. Amphipods (/ ˈ æ m f ɪ p ɒ d z /) range in size from 1 to 340 millimetres (0.039 to 13 in) and are mostly detritivores or scavengers.
