Amphibians are ectothermic, anamniotic, four-limbed vertebrate animals that constitute the class Amphibia. In its broadest sense, it is a paraphyletic group encompassing all tetrapods excluding the amniotes (tetrapods with an amniotic membrane , such as modern reptiles , birds and mammals ).
The addition of an invasive species will be very successful until the tadpoles learn to avoid it, which could cause even more pressure on this species. Amphibians worldwide are being infected with the fungus Batrachochytrium dendrobatidis (Bd) and the boreal chorus frog is no exception. Bd infects the keratinized skin of its host, which results ...

Scientists believe that the leading cause for the Wyoming toad's endangerment is chytrid fungus, which is impossible for the toads to avoid in their natural habitat. Another major reason for the failure of reviving the Wyoming toad population is that it is not a high priority movement; since the toad's discovery, there have been only three ...
