Thus you can understand my obvious dismay about a cowrie killing tapeworm described in a recent Science News article. The tapeworm wraps itself around the cowrie shell, poisons it with a deadly neurotoxin, and then slurps up the contents. The discoverer of this behavior found it by accident when he placed a cowrie shell in with the flatworm while collecting specimens. When he looked in later, there was a fat flatworm and no cowrie in the shell, oops.
