If you mean tongues, then yes, quite a few snakes have black tongues, but many also have red tongues, and some even have differently colored tongues than that. For example, the Red-Tailed Green Rat snake (Gonyosoma oxycephala) has a blue tongue.
Animals that have red tongues would be dogs, frogs, snakes, bears, There are a lot.
King snakes.....red touch yellow kill a fellow.....red touch black friend of Jack
No. There is not a set tongue color for poisonousand harmless snakes. A garter snake has both red and black on its tongue
No. Boas are all nonvenomous. They kill their prey by constriction. In talking about snakes the proper term is venomous rather than poisonous.
Technically garter snakes are venomous, but it is too mild to be a danger to humans.
There are snakes that have a mostly red coloration, but most snakes are not red.
No, as long as you only eat its flesh (muscle).
Red and yellow kill a fellow, red and black, venom lack. Also, look at the pupils. If the pupils are shaped like a cat's, real ovally, then it's poisonous. If it's round like a humans, it's okay. May be a primitive method, but I think that it works. Also, if you can see the snakes pupils, you are way to close, and should probably back away from it.
They are called baby red-bellied black snakes. well actually not really but that's the best i can do, get hold of a venomous snake fanatic if you want to know more.
Yes, they can bite you, if they feel threatened. Call your local animal control. ============== Yes, a king snake could bite you, which could break the skin. However, it is not as dangerous as actual poisonous snakes. The coral snake is poisonous and has the same colors as the king, though in a different pattern. The way to tell the difference is what color ring touches the red ring. Red and black, friend of Jack; Red and yellow, kill a fellow.
The Answer to this question is the Red Back Rattle Snake if you ever get bit by one of these snakes if you have a buddy next to you have him lick you dickhole for that it cures it in 2 minutes.
