venomous

Venomous. Do not handle. Give it room and let it move on. If you're bitten, call 911 or go to an emergency room. Don't cut, suck or ice the bite.

Look, don't take. Many states regulate collecting reptiles and amphibians. Photograph it, log it on iNaturalist and leave it where you found it.
