Some amphibian toxins can be lethal to humans while others have little effect.

Protein binding can be extraordinarily tight and specific ; for example, the ribonuclease inhibitor protein binds to human angiogenin with a sub-femtomolar dissociation constant (< 10 < sup >− 15 </ sup > M ) but does not bind at all to its amphibian homolog onconase (> 1 M ).

Seaplanes that can also operate from dry land are a subclass called amphibian aircraft.

Although the full reasons for the decline are uncertain, it can be at least partly attributed to the fatal amphibian fungal disease chytridiomycosis.

There are three sections to the house: Desert ( gila monsters, geckos and tortoises ), Rainforest ( dwarf crocodiles, terrapins and snakes ) and the Rearing Room where visitors can view the raising of reptiles and amphibian and also learn about the zoo's conservation work.

Seaplanes that can also take off and land on airfields are a subclass called amphibian aircraft.

An amphibious aircraft or amphibian is an aircraft that can take off and land on both land and water.

It can also reach sexual maturity as a larva, which no other amphibian can do.

Hedorah is confronted by Godzilla and Hedorah only an amphibian at the time is easily overpowered by Godzilla and retreats into the sea but returns shortly thereafter in a flying saucer shape demonstrating new, even deadlier forms which it can switch between at will.

Earlier researchers used these differences to support the division into five different species, while modern herpetologists understand that external morphology is not reliable for amphibian systematics and can be extremely variable, depending on nourishment, illness, and other factors even varying among individuals in a single population.

This number can be expanded to as many as four ( juvenile dirt-dragons as larva, " adult " graboids as pupa, Shriekers as subimago, and Ass-blasters as imago ) or reduced to as few as two ( Dirt-Dragons as larva and Ass-blasters as adults ; similar to the sharp lexical division of amphibian metamorphosis into tadpole and frog / newt ).

One of the largest extant species of amphibian in the world, they can grow from in mass and from in length.

The Ka-29 may form the first dedicated transport for the marine corps, the Ka-31's powerful radar can serve in over-the-horizon target acquisitions and early warning for Chinese surface ships, and the Be-200 jet amphibian would replace the SH-5 in maritime patrol duties and ASW.

As a result, more diverse larval amphibian communities that include species with differing susceptibilities can alter parasite infection success and the resulting pathology in sensitive host species.

A big, pompous amphibian wanting the entire rat population to be killed off so he can make room for his hundreds of offspring.

In typical amphibian development, eggs are laid in water and larvae are adapted to an aquatic lifestyle.

In typical amphibian development, eggs are laid in water and larvae are adapted to an aquatic lifestyle.

In 2010, eleven poison dart frogs were raised at WWT Slimbridge by amphibian keepers in pint glasses of water, topped up with shop-bought Rooibos tea.

An amphibious vehicle ( or simply amphibian ), is a vehicle or craft, that is a means of transport, viable on land as well as on water.

Because of a lack of surface water, amphibian presence in the monument is limited.

The Rinspeed Splash is a concept amphibian vehicle with hydrofoil design capable of 45 knots on water or nearly 200 km / h on land.

The Eighth Doctor and Charley decide to have a little peace and quiet in Renaissance Venice — except that he gets the date wrong by about six hundred years and discovers a cursed city about to sink below the water ... complete with a Duke who hasn't aged for a hundred years, amphibian gondoliers, a curator obsessed with his art collection and your typical mad cult leader.

The garden also provides wetland mitigation for a nearby industrial park to provide waterfowl and amphibian habitat, and offloads Silver Creek from water it would not naturally carry during low-flow months in the summer to address an Oregon Department of Environmental Quality requirement.

An illustrative tale involved a gourmet diner whose love for frog legs leads to a predictable amphibian revenge: he is left without lower limbs and is doomed to negotiate the world on a trolley.

4VAC15-20-50 defines a wild animal as " Any member of the animal kingdom, except domestic animals, including without limitation any native, naturalized, or nonnative ( exotic ) mammal, fish, bird, amphibian, reptile, mollusk, crustacean, arthropod or other invertebrate, and includes any hybrid of them, except as otherwise specified in regulations of the board, or part, product, egg, or offspring of them, or the dead body or parts of them.

Possible reproductive modes include full amphibian spawning with aquatic tadpoles, internal fertilization with or without ovoviviparity, aquatic eggs with direct development or some combination of these.

He thinks he will make a fortune from the frog, but unfortunately the amphibian will not sing for anyone but him.

Amphibious floats that could be attached to any aircraft were developed, turning any aircraft into an amphibian, and these continue to be essential for getting into the more remote locations during the summer months when the only open areas are the waterways.

However, true flying boats have largely been replaced by seaplanes with floats and amphibian aircraft with wheels.

Italian Air Force Piaggio P. 136 during takeoff retracting the wheels that make it an amphibian.

Hundreds of species of birds, more than a dozen fish species and even a few reptile and amphibian species have been documented.

Many predators, including various fish, mammal, reptile and even amphibian species, feed on caiman eggs and small young.

Due to environmental degradation and the sensitive nature of amphibians to pollution, Costa Rica has seen declines and even extinctions in amphibian populations.

Chytridiomycosis has been linked to dramatic population declines or even extinctions of amphibian species in western North America, Central America, South America, eastern Australia, and Dominica and Montserrat in the Caribbean.

In addition, most species of amphibian have granular glands that secrete distasteful or poisonous substances.

Altogether, over two hundred toxins have been isolated from the limited number of amphibian species that have been investigated.

Dramatic declines in amphibian populations, including population crashes and mass localized extinction, have been noted in the past two decades from locations all over the world, and amphibian declines are thus perceived as one of the most critical threats to global biodiversity.

Any decline in amphibian numbers will have an impact on the patterns of predation.

However, some species exhibit sex-role reversed behavior in which it is males that are most selective in mate choice ; the best-known examples of this pattern occur in some fishes of the family Syngnathidae, though likely examples have also been found in amphibian and bird species.

Claws appear to have evolved separately in the amphibian and amniote line.

Among the amphibian species found are the Cascades frog and the Rough-skinned Newt, the latter being a common far western USA taxon ; in fact, examples of neoteny have been found in individual newts of this species within the county.

There have been 38 reptile and 19 amphibian species recorded in Oxley Wild Rivers National Park.

Declines in amphibian populations, including population crashes and mass localized extinctions, have been noted since the 1980s from locations all over the world.

This found that 32 % of species were globally threatened, at least 43 % were experiencing some form of population decrease, and that between 9 and 122 species have become extinct since 1980., the IUCN Red List, which incorporates the Global Amphibian Assessment and subsequent updates, lists 486 amphibian species as " Critically Endangered ".

Declines have been particularly intense in the western United States, Central America, South America, eastern Australia and Fiji ( although cases of amphibian extinctions have appeared worldwide ).

However, since this initial scepticism, biologists have come to a consensus that declines in amphibian populations are a real and severe threat to biodiversity.

Numerous potential explanations for amphibian declines have been proposed.

However, many amphibian declines or extinctions have occurred in pristine habitats where the above effects are not likely to occur.

In Badlands National Park, scientists have recorded the presence of 37 mammal species, 9 reptile species, 6 amphibian species, 206 bird species, and 69 butterfly species.

Movement of live or unfrozen, unskinned amphibians is one potential way in which deadly amphibian diseases such as Batrachochytrium dendrobatidis and Ranavirus may be transported around the world, and despite recommendations on preventing disease spread from the OIE, which regulates the international spread of epizootic diseases, few countries have adopted these recommendations as law.

In recent years, bullfrogs have contributed to the decimation of native amphibian species populations at the creek.

Under phylogenetic taxonomy, amphibians is not monophyletic, in that the amniotes ( reptiles, birds and mammals ) have evolved from an amphibian ancestor and yet are not considered amphibians.
