Amphibians are members of the class Amphibia, whose living forms include frogs, toads, salamanders, newts and caecilians.

Amphibians typically have a larval stage that lives in water but there are many different behavioural adaptations that have developed among species to bypass this necessity.

Amphibians have a urinary bladder and nitrogenous waste products are excreted primarily as urea.

Amphibians have a juvenile stage and an adult stage and the circulatory systems of the two are distinct.

Amphibians: Frogs are the most crucial amphibian species in wetland systems.

Amphibians like toads and frogs have been featured also, and are depicted as lower creatures that live in more basic tribal systems and usually serve not as the primary villains but as secondary distractions to heroes.

The first two books are repackaged in one volume, and Adrian Mole: The Lost Years includes The True Confessions and The Wilderness Years, as well as a bonus not available separately, " Adrian Mole and the Small Amphibians ".

Amphibians and reptiles are rarely preyed upon.

Amphibians such as frogs are well represented in moorlands.

According to The Illustrated Encyclopedia of North American Reptiles and Amphibians, Mudkip and its evolutions are based on salamanders.

Amongst other vertebrates found in the National Park are fishes including Channa striatus, Channa punctatus, Cyprinus carpio, Wallago attu and Puntius sophore ( Pool barb ), Amphibians and Reptiles including Keel back Tortoise, Viper, Krait, Cobra, Water cobra, krait ( banded ) Bungarus fasciatus, Asian rat snake ( Beauty rat snake ), python, Russel's viper ( Daboia ), checkered garter snake and Common Lizard ( Viviparous Lizard ).

Amphibians and reptiles are mostly frogs, toads and lizards.

Ichthyophis, sometimes called the Asian caecilians are a genus of caecilians ( Limbless Amphibians ) found in Southeast Asia, southern Philippines, and western Indo-Australian Archipelago.

Amphibians in particular are able to take refuge in water or very wet mud.

Amphibians such as the Columbia spotted frog, tiger salamander and the boreal toad are relatively common.

Amphibians were the dominant land vertebrates, of which one branch would eventually evolve into reptiles, the first fully terrestrial vertebrates.

Amphibians also use their skin for respiration and some small terrestrial salamanders rely entirely on this and have no lungs.

Amphibians evolved adaptations that allowed them to stay out of the water for longer periods.

Amphibians breathe by means of a pump action in which air is first drawn into the buccopharyngeal region through the nostrils.

Amphibians often eat the sloughed skin.

Amphibians have a skeletal system that is structurally homologous to other tetrapods, though with a number of variations.

Amphibians swallow their prey whole, with some chewing done in the oral cavities of some species, so they possess voluminous stomachs.

Amphibians possess a pancreas, liver and gall bladder.

Amphibians have two kidneys located dorsally, near the roof of the body cavity.

Amphibians usually swallow food whole but may chew it lightly first in order to subdue it.

Amphibians have soft bodies and thin skins, lack claws, defensive armour or spines and seem relatively helpless.

Amphibians also retain the fifth connecting vessel, so that the aorta has two parallel arches.

Amphibians, reptiles, and birds use the same orifice for excreting liquid and solid wastes, and for copulation and egg-laying ; this orifice is known as the cloaca.

Amphibians include the green toad, American toad, common tree frog, and the Cretan marsh frog.

Amphibians and reptiles have no ovarian medulla ; the central part of the ovary is a hollow, lymph-filled space.

Amphibians were diverse and common ; some were several meters long as adults.

Amphibians were the dominant tetrapods until the mid-Carboniferous, when climate change greatly reduced their diversity.

Amphibians originally thrived in the marshes, sloughs, side-channels and oxbow cutoffs because of their warmer water, abundance of vegetation and nutrients, lower population of predators, and slower current.

Amphibians have a three-chambered heart.

** The first known underwater diving club in Britain, " The Amphibians Club ", is formed in Aberdeen by Ivor Howitt ( who modified an old civilian gas mask ) and some friends.

Try that late winter pickup when you are so tired of cold and snow that you feel you just can't take another day of it.

Occasionally, you may come across one or two bumblebees in the cold season, when you are turning over sods in your garden, but you have to be a really keen observer to see them at all.

Both man and wife should be aware of the fact that a lack of climax, and even the absence of the anticipated keen pleasure are not a sign that the wife may be cold or frigid.

Some perennials and biennials are grown in gardens as annuals for convenience, particularly if they are not considered cold hardy for the local climate.

The majority of abalone species are found in cold waters, off the Southern Hemisphere coasts of New Zealand, South Africa and Australia, and Western North America and Japan in the Northern Hemisphere.

Winters are mildly wet and spring-like, though subject to cold spells.

Among its adaptations for cold survival are its deep, thick fur, a system of countercurrent heat exchange in the circulation of paws to retain core temperature, and a good supply of body fat.

This consumption grows during autumn and winter, or in the cold regions of the country ; there are two dates where consumption of chocolate infusions is traditional in the primary educational centres: 25 May and 9 July, that is, the two national dates of Argentina.

For example, cold weather crops like rye, oats, wheat, and apples are expected to decline by about 15 % in the next fifty years and strawberries will drop as much as 32 % simply because of projected climate changes of a few degrees.

There are, however, occasional cold weather front that cause temperatures to fall to near freezing levels.

Temperatures within a given winter are highly variable as well ; extended cold snaps of forty below zero can be followed by unseasonable warmth with temperatures above freezing due to chinook wind effects.

* Alpha brasses with less than 35 % zinc, are malleable, can be worked cold, and are used in pressing, forging, or similar applications.

Winters are relatively cold with average high temperatures of and lows of.

A few Southern Interior valleys have short cold winters with infrequent heavy snow, while those in the Cariboo, the southern part of the Central Interior, are colder because of their altitude and latitude, but without the intensity or duration experienced at similar latitudes elsewhere in Canada.

Winters are cold and damp, also containing the most rainfall, there can be snow on the ground which will last for a week or two.

The south of the country is most exposed to cold winds during the winter period ( early May to late August ) when average temperatures are around.

Adult Culicoides are killed by cold winter temperatures, and BTV infections typically do not last for more than 60 days, which is not long enough for BTV to last until the next spring.

In cold moulding very thin strips of wood are laid over a form or mould in layers.

The four possible types of matter are known as cold dark matter, warm dark matter, hot dark matter, and baryonic matter.

Remaining issues, such as the cuspy halo problem and the dwarf galaxy problem of cold dark matter, are not fatal to the dark matter explanation as solutions to such problems exist which involve only further refinements of the theory.

These are processes which create compound nuclei at low excitation energy (~ 10-20 MeV, hence " cold "), leading to a higher probability of survival from fission.

The dish is so named because it makes bubbling and squeaking sounds during the cooking process, and the cold chopped vegetables ( and cold chopped meat if used ) are fried in a pan together with mashed potatoes or crushed roast potatoes until the mixture is well-cooked and brown on the sides.
