@ShaulaEvans okay, here are some fun/gross/terrifying bug facts about polycheate worms (which live in the ocean):

1. The Bobbitt Worm is a marine ambush predator that burrows in ocean sediment and then shoots out to grab prey with its mandibles, the force of which sometimes cuts prey in half. It grows up to 3 meters long in extreme cases, although it's only about 25 millimeters in diameter. At least one article I read mentioned toxic bristles, but I wasn't able to find a legitimate source for that and suspect it was sensationalization.

2. The Bearded Fireworm does have toxic bristles (as do other fireworms). They can cause a painful sting that lasts for hours. They're also quite beautiful.

3. The Palolo Worm spawns by growing tail segments filled with sperm or eggs, and then on a specific night tied to the lunar & solar cycles, releasing these segments to float to the surface, where they disintegrate into a frothy mass. They're apparently delicious fried in coconut oil.
