The great egret and the rough-skinned newt

The rough-skinned newt or roughskin newt, (Taricha granulosa), produces a neurotoxin called Tetrodotoxin or (TTX).
The neurotoxin TTX is said to be 10,000 times more toxic than cyanide and two to three times stronger than the venom of the world's "deadliest" snake, the Inland Taipan from Australia. It is the same toxin found in Puffer Fish and is exuded through the skin when the newt is disturbed.
While some of the common Garter Snakes have evolved with an immunity to the toxin, and I believe that no other animal has. To the best of my knowledge Herons and Egrets have not and will die shortly after eating one. This egret played with the newt for at least a half hour, holding it gently and washing it often. When the bird finally saw me, it flew farther away, carrying the newt with it. While I did not see it swallow the newt, I looked up, and the newt was gone. Perhaps it was washing out the TTX to a point where it wasn't toxic enough to harm the bird and then ate it? Or it was just playing with it? I took these yesterday and I saw no signs of a dead egret later, or today.
Please download for a good look at the newt.

Victor, first off thank you for the education, I never knew any newt was this dangerous. The set of photos are fantastic and DDLs show off the sharp in focus results you got.

Thanks for looking & commenting Greg. They are only dangerous if you eat them or touch them & get the toxin in your eye. There are people that actually keep them as pets. Crazy!
