  1. An insect half the size of a whale is still pretty massive.

    I now understand why they need so much venom.

  2. I’m not sure but I think they have like a certain amount of venom they’re supposed to spend over time untill they refill during winter. But if instead of using one bit of it at a time over the course of several months they use it all at once on then yeah it’s gonna be hella deadly.
    (Talking mosly about snakes)

  3. It’s the equivalent of using 1(one) thermonuclear warhead to deal with a mosquito inside your bedroom

  4. Let’s say a snake bites a mouse, and the mouse escapes and dies later, the snake lost his prey and wasted energy by poisoning his mouse. The mouse died, but the snake got nothing.

    Let’s say the snake made super venom. It barely costs any more energy to make. The snake bites the mouse and the mouse dies immediately. The snake eats and it gained more energy then it lost.

  5. They’re incredibly venomous because it was selected for over millions of years. They became more venomous because the ones that gained mutations towards that end lived to reproduce while their slightly less venomous counterparts did not. Sometimes it’s a matter of making sure your meal doesn’t slip away before it dies.

  6. The reason this happens is that the prey/predator they are using the venom against evolves alongside them and it becomes an arms race between defence against said toxin and creating a stronger toxin that the prey cannot defend against.

    Since most of these animals have very short life spans they evolve much faster and we get for instance a snake that can kill 100 men with one bite against a weasel.

    I found the article

  7. Freak accident. Most of the time evolution doesn’t do more than it needs to, but in rare cases, such as in poison/venom (because how other animals metabolize it/react varies), the mutation that makes the first descendants venomous just happened to be really strong to begin with. If weaker successful mutations don’t arise and dilute the strength in the population, then the excessively strong ones will persist.

  8. It’s not about protection. It’s about sending a message:
