Answer:
animals that live both in water and land
Answer:
Amphibians, in the simplest definition, are animals that live in both water and on land. The word ‘Amphibia’ means dual lives. Amphibians are cold-blooded vertebrates that include the well-known frogs and toads. Being cold-blooded means that they depend on environmental sources of heat to regulate their body heat and temperature. The class of Amphibia is made up of more than 3,500 species which include the various order of amphibians. Most amphibians begin their lives in water and eventually adapt to life on land by developing lungs and limbs that allow them to move on land. The larvae mature while in the water. At this young stage, the offspring breathe through the gills and after some time they develop lungs through a process known as metamorphosis. The class of Amphibia is made of three orders namely; Anura (toads and frogs), Urodela or Caudata (newts and salamanders), and Apoda or Gymnophiona (caecilians).
