For example, a study found the toxicity of coal-tar pavement on eastern newts sublethal, decreasing their righting ability and swimming speed. [40] Wild eastern newts are known hosts of Batrachochytrium dendrobatidis and Ranavirus , as well as the mesomycetozoan Amphibiocystidium ranae [ 41 ] .
A rough-skinned newt underwater A rough-skinned newt at Brice Creek in Oregon. Throughout much of the newt's range, the common garter snake (Thamnophis sirtalis) has been observed to exhibit resistance to the tetrodotoxin produced in the newt's skin. While in principle the toxin binds to a tube-shaped protein that acts as a sodium channel in ...
Taricha newts can be lethal to humans if ingested, and at least one human fatality occurred in Oregon from eating a rough-skinned newt. Eastern newts of the genus Notophthalmus (= Diemictylus of earlier authors) also secrete tetrodotoxin, but in lesser amounts.

Most toxic amphibians are poisonous to touch or eat. These amphibians usually sequester toxins from animals and plants on which they feed, commonly from poisonous insects or poisonous plants . Except certain salamandrid salamanders that can extrude sharp venom-tipped ribs, [ 1 ] [ 2 ] and two species of frogs with venom-tipped bone spurs on ...
The Pacific newts (Taricha) and the Eastern newts (Notophthalmus) with together seven species are the only representatives in North America, while most diversity is found in the Old World: In Europe and the Middle East, the group's likely origin, eight genera with roughly 30 species are found, with the ribbed newts (Pleurodeles) extending to ...
The species has officially been named tylototriton gaowangjienensis, or the Gaowangjie crocodile newt. Related: China Plans to Send New Pandas to the U.S., Signs Agreement with the San Diego Zoo .
The North American rough-skinned newt (centre) was killed by the fungus in laboratory tests. [4] The Japanese fire-belly newt (right) is somewhat resistant and could have been a vector for the pathogen's introduction to Europe. [4] The Eastern Newt, which is found across the eastern United States and parts of Canada is a susceptible Bsal host ...
