"Flatworms are flat creatures, and while some types look like sea slugs, they have little else in common. Some types are venomous and produce a poison similar to the kind blowfish are famous for. Flatworms are hermaphrodites and mate by fighting to determine the loser, who then bears the eggs."

The word "flatworm" is used as an umbrella term for a vast amount of primitive creatures, ranging from as large as two feet long to completely invisible to the naked eye. The flatworm family, Platyhelminthes, consists of many dangerous parasites such as tapeworms and flukes, which are infamous for attacking livestock, humans, and many other animals—at least one species is known to infest whales. The nonparasitic animals usually called flatworms, however, resemble sea slugs or worms and are generally harmless to humans.
