Probably not. Taricha newts can exude tetrodotoxin on their skin. This is the same type of poison found in many deadly marine animals, like pufferfush and scorpion fish. Most predator will quickly spit out a Taricha newt or become paralyzed. When I was child, I used to pick up terrestrial Taricha newts that I'd find in the woods. I never noticed any ill effects, but then I was just touching a dry newt with dry hands. Also I believe they only release the toxin when threatened, because even the newts are not completely immune to the toxin.I saw once a goldfish try to swallow a baby newt whole, with half the newt body already inside the fish. Yuck. I don't know if the fish completed his meal or not.
