Caecilians are limbless amphibians that can be easily mistaken for snakes. Though caecilians are only distantly related to their reptilian cousins, researchers describe specialized glands found along the teeth of the ringed caecilian (Siphonops annulatus), which have the same biological origin and possibly similar function to the venom glands of snakes. As such, caecilians may represent the oldest land-dwelling vertebrate animal with oral venom glands.

Researchers have developed a new non-invasive method to count individual fish by measuring the concentration of environmental DNA in the water, which could be applied for quantitative monitoring of aquatic ecosystems.
