a group of animals able to function on land and in water; frogs, toads, salamander
are cold-blooded creatures that live in a moist habitat They hatch from eggs laid in water, where they spend the first part of their life cycle Amphibians begin life in water, breathing through gills, and end up living on land breathing through lungs The Prairie's most common amphibians include frogs and salamanders
Frogs, toads, salamanders and newts These animals require water to complete their reproductive life cycles Amphibians are sometimes lumped with reptiles in a common slang term, ‘herps’ See Reptile, Herp
Vertebrate animals that have life stages both in water and on land (e g , salamanders, frogs, and toads) Animals capable of living either in water or land
An amphibian is an organism, such as a frog, toad, salamander, or some types of newts, having an aquatic early stage (e g tadpole) and developing air-breathing lungs as an adult (e g frog)
A lower form of the vertebrates having blood the same temperature as its surrounding medium, without scales, feathers, fur, or hair, which possess functional gills in the early stage of development Most are aquatic as young and terresterial as adults
A class of cold-blooded animals with moist glandular skins Their young pass through a larval, usually aquatic stage (for instance, the tadpole stage of the frog) before they metamorphose into adult form
Any of a class of vertebrates that regulate their body temperature externally; lay shell-less eggs in wet areas; live in water during early development and live both in water and on land as adults; and use lungs, gills and their skin for breathing Most have four legs and smooth, moist skin without scales
n any of various cold-blooded, smooth-skinned vertebrate organisms of the class Amphibia, as a frog, that typically hatch as aquatic larvae that breathe by means of gills and metamorphose to an adult form with air-breathing lungs
An aircraft that can fly off of water or land The wheels retract into the hull or floats, depending upon the type of aircraft An amphibian can land on water and then extend the landing gear to allow it to pull up onto the shore Many seaplane bases had ramps to allow the airplanes to pull up onto dry land parking areas
Any vertebrate of the class Amphibia: cold-blooded tetrapods that breathe by means of gills in the early stages of life and by means of lungs in the later stages
Cold-blooded, smooth-skinned animals of the class Amphibia, including frogs, toads, and salamanders, characteristically hatching as aquatic larvae that breathe by means of gills and metamorphose to an adult form having air-breathing lungs
An animal that typically lives partially in an aquatic habitat (breathing by gills) as young and primarily in a terrestrial habitat (breathing by lungs and through moist skin) as an adult, e g frogs
cold-blooded vertebrate typically living on land but breeding in water; aquatic larvae undergo metamorphosis into adult form an airplane designed to take off and land on water a flat-bottomed motor vehicle that can travel on land or water
An amphibian is a vehicle which is able to move on both land and water, or an aeroplane which can land on both land and water. animals such as frogs that can live both on land and in water. Any member of a class (Amphibia) of cold-blooded vertebrate animals that includes more than 4,400 species in three groups: frogs and toads (order Anura), salamanders (order Caudata), and caecilians (order Apoda). Probably evolved from certain fish species of the Early Devonian period (417-391 million years ago), amphibians were the first vertebrates to move from an aquatic environment to land. Most species have an aquatic larval, or tadpole, stage that metamorphoses into a terrestrial adult, but a few species spend their entire life in water. Amphibians are found worldwide, the majority in the tropics
