According to the U.S. Fish and Wildlife, the most venomous rattler is the tiger rattlesnake, followed by the Mojave rattler. The two diamondbacks, eastern and western, rank somewhat lower in toxicity, however, being large snakes, the massive amount of venom yield can be fatal. I would rank the western as a 7, because of venom amount injected.
Eastern and western diamondbacks are large, heavy bodied snakes, and are capable of injecting copious amounts of venom. Both are capable of killing a grown man in an hour or two if bites are not treated with antivenin. However, ounce for ounce, the most potent venom of any rattlesnake belongs to the Mojave rattlesnake.
No, rattlesnakes are found only in the Americas, not in Portugal.
Red Diamondback rattlesnakes, like all rattlesnakes, are equipped with fangs and venom and will use them if threatened .
I'm not sure what you are asking in your question. However, baby rattlesnakes come well equipped with fangs and venom and are capable of delivering a potentially deadly bit to a human.
Rattlesnakes are not poisonous but they are venomous. A poison is something that must be ingested to do damage. A venom must be injected. Snake venom can be eaten and will cause no harm unless there is an open sore in the mouth or stomach that provides entry of the venom into the blood and tissues.
no, venom is in the head not the tail
Rattlesnakes have a venom that can be deadly if not properly and promptly treated in a medical facility. When in rattlesnake country, use all precautions, dress appropriately and do not place hands or feet anywhere that you cannot see.
None. The venom is not poisonous. It can be, in most case, eaten without problems. Venom must be injected into body tissues to cause harm. All rattlesnakes have venom with varying degrees of toxicity.
No. The sacks which contain a rattlesnakes venom are just held at the base of its mouth.
Like all venomous snakes, rattlesnakes produce their venom in glands inside the head that are similar to salivary glands.
Rattlesnakes release their venom through their fangs
Rattlesnakes are not necessarily immune to their own venom. If they bit themselves and injected venom, they would most likely die. However, venom is not poisonous so they could safely eat food with venom. They do it all the time, each time they eat. Venom is only dangerous when injected into tissues.
they have NO venom in them.
