Its skin can produce a powerful neurotoxin called tetrodotoxin. The toxin prevents nerve cells from firing correctly, which ultimately causes paralysis and death.

Why is the newt so toxic?

Bacteria on the skin of some rough-skinned newts may make those newts deadly to predators. The microbes make a paralyzing poison called tetrodotoxin.

Can I pick up a newt?

We do not advise that you attempt to move newts or their eggs away from your pond: by taking them to a different pond you may unwittingly transfer various diseases and invasive plants. Also, many amphibians may try to return and there is a danger that some may suffer as a result of being placed in an unsuitable area.
