If snakes and worms give birth to children, they should look like this! The "salamander" has no limbs and looks like a snake or a large earthworm at first glance, but it is actually an amphibian like a frog. Although salamanders have nothing to do with snakes, scientists have found that they may be able to give people a "vicious" bite.

Brazilian biologist Carlos Jared has spent 30 years studying the salamander, a creature with many mysteries that remain unsolved. He and the Utah State University research team recently announced a major discovery that in addition to the toxic secretions in the skin, the salamander even has tiny glands filled with liquid in the upper and lower jaws, which are connected to the bottom of their teeth in slender tubes.

The research team published the results in the journal on the 3rd. Jared said the findings suggested that the salamander's mouth might be studded with poisonous teeth, which were no different from the poisonous fangs of some snakes. Emma Sherratt, an evolutionary biologist who was not involved in the study, also said that salamanders may have the same powerful teeth as snakes.
This is the first time scientists have found toxic glands in the mouths of amphibians, representing that amphibians may have appeared more than 100 million years before snakes in their evolutionary history, and will also make them the oldest users of "poisonous fangs" on Earth.
