The six-eyed sand spider has one of the MOST POTENT SPIDER VENOMS on Earth — drop-for-drop, the most toxic spider venom yet measured to vertebrate animals in laboratory studies (Newlands & Atkinson 1988).

Bullet ant venom contains poneratoxin, a peptide that paralyzes insect prey and is being studied as a template for next-generation insecticides.

Glasswing caterpillars eat toxic Cestrum plants and store the alkaloids — making the adults distasteful to predators.

When threatened, ladybugs 'reflex bleed' — releasing yellow alkaloid-laced hemolymph from their leg joints.

Monarch caterpillars accumulate cardiac glycosides from milkweed — making the adults toxic to most predators.

When threatened, giant millipedes release a defensive secretion containing benzoquinones and hydrogen cyanide.

Caterpillars eat toxic Omphalea plants and store the alkaloids — the brilliant adult colors warn predators 'I'm poisonous.'
