The term "biotoxin" is usually used to explicitly ensure the biological origin. Biotoxins is additional classified, for instance, as fungous biotoxins, microbic biotoxins, plant biotoxins, or animal biotoxins. Toxins created by microorganisms are vital virulence determinants accountable for microbic pathogenicity and/or evasion of the host immunologic response. Biotoxins vary greatly in purpose and mechanism, and may be extremely advanced (the venom of the cone snail contains dozens of tiny proteins, each targeting a selected nerve channel or receptor), or relatively tiny protein.
Biotoxins in nature have 2 primary functions:
Predation, like in the spider, snake, scorpion, jellyfish, and wasp
Defense as within the bee, ant, termite, honey bee, wasp, and poison dart frog
