Some species also have dermal calcite scales and are the only living amphibians known to possess them.

Are caecilians important?

Generally assumed to be rare and highly elusive, some studies have shown that at least some caecilian species can be abundant if searched for (Measey 2004), and in fact present in sufficient numbers to be (presumably) ecologically significant, especially so given their predation on soil ecosystem engineers (Jones et al ...

Do amphibians breathe with lungs or gills?

Most amphibians breathe through lungs and their skin. Their skin has to stay wet in order for them to absorb oxygen so they secrete mucous to keep their skin moist (If they get too dry, they cannot breathe and will die).

How do caecilians breathe?

Like all amphibians, caecilians breathe primarily through their skin but will occasionally come to the surface to breathe air through their lungs. ...
