1. definition of amphibians
A cold-blooded vertebrate animal distinguished by having an aquatic gill-breathing larval stage followed (typically) by a terrestrial lung-breathing adult stage.
The word "amphibian" is derived from the Greek term amphíbios, which means "both kinds of life".
2. BASIC FACTS
It is assumed that amphibians originated from ancient lobe-finned fish that evolved multi-jointed leg-like fins with digits that enabled them to crawl along the sea bottom. Some of these fish also developed primitive lungs to help them breathe air.
In almost every country, living on or under ground, in trees and in water. Most amphibians live part of their lives underwater and part on land. Most areas with high amphibian diversity have a few common characteristics, namely warm climates with high annual rainfall.
There are over 7,000 different species of amphibian, of which frogs account for nearly 90%
The smallest amphibian is a frog from New Guinea (Paedophryne amauensis) with a length of just 7.7 mm (0.30 in). The largest living amphibian is the 1.8 m (5 ft 11 in) Chinese giant salamander (Andrias davidianus).
Between 1 and 10 years, depending on species (for final stage of amphibian). Lifespan of the larval stage has been recorded to last between 10 days to 20+ years!
Fertilization may be internal or external and most are egg-layers (oviparous). Mating in frogs, for example, occurs when males typically move to potential breeding sites and begin calling to attract females. When the females approach, the males clasp them around the back and fertilize the eggs as they are deposited. Some salamanders use smell to locate a suitable mate.
Adult amphibians are carnivores and predators. They eat a variety of food including spiders, beetles, and worms. Some of them, like frogs, have long tongues with sticky ends that they flick out to catch their prey. The larvae of many amphibians mostly eat plants.
