To facilitate this, these salamanders have a dense network of ...

Except certain salamandrid salamanders that can extrude sharp venom-tipped ribs, [ 1 ] [ 2 ] and two species of frogs with venom-tipped bone spurs on their skulls, amphibians are not known to actively inject ...
More than a third of the worlds salamanders live in the United States, [25] and 40% of those salamanders are already threatened.

While roughly 3,000 species of spiders are found throughout the U.S., very few pose a direct threat to humans. Spider bites are rare, and medically significant incidents are even less common ...
Newts, as with salamanders in general and other amphibians, serve as bioindicators because of their thin, sensitive skin and evidence of their presence (or absence) can serve as an indicator of the health of the environment. Most species are highly sensitive to subtle changes in the pH level of the streams and lakes where they live. Because ...
