The hedgehog (Erinaceidae), the mongoose (Herpestidae), the honey badger (Mellivora capensis) and the opossum are known to be immune to a dose of snake venom.
The mongoose is known for its ability to fight and kill venomous snakes, especially cobras. Their specialised acetylcholine receptors render them immune to venom.
“It is important to note that this resistance is not absolute – we are not immune to cobra venom, just much less likely to die than other primates.” Resistance to cobra venom has a cost – receptors that are resistant to cobra venom don't work quite as well.
Although cats are more resistant to venom on a milligram of venom to kilogram of body mass basis than dogs, they also have smaller body sizes. As a result of all of these factors, cats that have been bitten by venomous snakes may present to veterinary clinics in a more serious condition.
The researchers found adaptations in Komodo dragon genes involved in coagulation that make these lizards immune from the venom anti-coagulant, protecting them from bleeding to death when attacked by another of their own species.
Though a snake-eating species, King Cobra is not fully immune to snake venoms, as it can be envenomed and killed by another King Cobra or venomous snakes.
So far scientists fully understand venom resistance in only four mammals - mongooses, honey badgers, hedgehogs and pigs - as well as several snakes. The golden poison frog is one of the most toxic animals on Earth, deadly to almost all animals except one.
We have noted at Walkabout Park that most kangaroos bitten by snakes are hand-raised kangaroos. We have seen a disproportionately larger number of hand-raised kangaroos bitten, relative to wild raised kangaroos.
Their primary form of protection is the venomous bite at the ends of their fangs. This venom is potent enough to paralyze or even kill some of its predators—including tigers! In addition to this deadly weapon, cobras rely on their size and agility to ward off potential threats.
Pythons are not immune to snake venom, while rattlesnakes are not immune to being crushed alive.
Venoms are generally not toxic if swallowed, and must be injected under the skin (by snakes, spiders, etc.) into the tissues that are normally protected by skin in order to be toxic. However, we do NOT recommend drinking venom!
Antivenom is the treatment for serious snake envenomation. The sooner antivenom can be started, the sooner irreversible damage from venom can be stopped. Driving oneself to the hospital is not advised because people with snakebites can become dizzy or pass out.
Now you know the answer to “are snakes immune to their own venom”. Whether through eating prey that has been injected with venom or through a bite from a snake from the same species, snakes are immune to their own venom.
What predator would even try to attack a cobra? The snake's biggest enemy is the mongoose, which is quick enough to dart in and bite the back of the cobra's neck before the snake can defend itself.
Mongooses, which have some resistance to mamba venom and are often quick enough to evade a bite, will sometimes harass or take a black mamba for prey, and may pursue them in trees. The similarly predatory honey badger also has some resistance to mamba venom.
An anaconda would win a fight against a king cobra. This outcome assumes that both of these creatures met in an open area that doesn't allow an ambush to happen. Otherwise, the anaconda might just snatch the water-loving king cobra into the water and make for a much less interesting fight.
A Komodo dragon would win a fight against a king cobra.
Both creatures are ambush predators, but the king cobra must rely on its venom to kill its enemy before it is attacked and killed.
At some point during this incredibly dangerous fight, the python was bitten by the ultra-venomous king cobra. Yet, the reticulated python - the world's longest and heaviest snake - remained constricted around the king cobra and killed the cobra while too being dead.
However according to statistics released by the National Coronial Information Service, eastern browns are responsible for the majority of snake bite deaths. Up to 65 per cent of fatalities between 2000 and 2016 were attributed to the venomous species, which is found across most of eastern Australia.
Another common plant remedy was the sap of the Native or Cherry Ballart (Exocarpas cupressiformis), used for snake bites.
Introducing the most venomous snake in the world and epic predator of the Australian outback! The inland taipan is otherwise known as the fierce snake or small scaled snake.
The inland taipan (Oxyuranus microlepidotus) is considered the most venomous snake in the world with a murine LD 50 value of 0.025 mg/kg SC. Ernst and Zug et al. 1996 list a value of 0.01 mg/kg SC, which makes it the most venomous snake in the world in their study too. They have an average venom yield of 44 mg.
The Box Jellyfish is the most venomous animal in the world. Death can occur minutes after being stung. There are 51 species of box jellyfish, and four — Chironex fleckeri, Carukia barnesi, Malo kingi, and Chironex yamaguchii — are highly venomous!
Anti-venom is most often made from sheep's blood. The sheep swelled for about 2 days but the blood of the lamb destroyed the venom of the serpent.
