Question

How do venomous animals produce and store toxins without harming themselves?

In: Biology

Answer 1

You know how you can hold a bottle of poison, but if you don’t drink it nothing happens? So like that. They store it in a separate “container” within their body so that toxins don’t interact with anything important.

Answer 2

Like a venomous snake? Is their venom only harmful to human blood??
