Pseudoscorpions are small arachnids that possess venom, but it is not harmful to humans. Their venom is primarily used for subduing small prey, such as insects. While they can bite and may cause mild irritation or allergic reactions in some people, their venom is not lethal to humans. Overall, they are considered harmless to us.
It can kill a human in 3 hours if not treated
No. Most of them do not have teeth long enough to penetrate human skin, and those that do, have venom too mild to kill a human.
Not unless you have an allergic reaction to their venom.
if the right anti venom is on hand you could survive
Yes, many animals can kill humans through sheer strength or through toxic venom.
No, butterflies do not have venom that can harm or kill humans.
No. But the crane fly has enough venom in it to kill a human. Thankfully its small mouth is not big enough to puncture the skin rendering the venom useless against humans, but not insects that it preys on. e.g. gnats and stuff :D
Platypuses do not kill people. Their venom can cause agonising, almost paralysing pain, but it cannot kill a healthy human being.
with anti-venom
The venom of a Mangrove snake is not considered potent enough to cause death in humans.
No, it can kill you.
probably Black mambas as they use a neurotoxic venom which can kill an unlucky human in minutes, depending on the size and well being of the human though it could take 30-60 minutes but the least is 20 minutes
