Scientists Discover New Species of Amphibians with Snake-Like Venom Glands

When we talk about venomous creatures, the first concept in our thoughts includes reptiles like snakes, lizards, and salamanders. Bringing a change into our perspective, a group of scientists from Brazil and the US has observed a species of amphibians, ringed caecilian (Siphonops annulatus)with oral venomous glands.

These limbless amphibians are usually located in regions with tropical climates, which consist of Africa, Asia, and America. Their habitat includes water bodies or self-made burrows. As they are almost blind, those creatures rely upon facial tentacles and slime to navigate.

Utah State University’s Professor Edmund ‘Butch’ Brodie (Jr) referred to that at the same time as we typically think amphibians like frogs and toads are basically harmless, there are “a number of amphibians that save nasty, toxic secretions of their pores and skin to discourage predators.” Brodie is also the co-author of the study.

The senior writer Dr. Carlos Jaredadded that caecilians are regarded to provide two styles of secretions: a poisonous one of their tail and mucus in their head. Dr. Jared is the director of the Structural Biology Lab at the Butantan Institute in São Paulo.


“Because caecilians are one of the least-studied vertebrates, their biology is a black box complete of surprises,” he stated.

The research published in the magazine iScience on July 3.

To study in addition to these creatures and their body, the crew conducted initial biochemical checks on the fluid in their glands. It was set up that these incorporate the phospholipase A2 enzymes, a fat-slicing protein that is normally discovered in animal venoms.


However, as Dr. Jared referred to, “these amphibians can’t inject their venoms and as a substitute relies on an attacker urgent on their pointy bits.”
