i always wonder when they do those shots of people gazing into the test-tube at the horror - a bit like on csi where they try and make forensics look interesting: "look i can see the evidence with my naked eye!" i digress however: this thing is remarkably specialised (stinging select parts of the brain against a struggling prey) and absolutely horrific, the worst part is the roach is alive till almost the end.

behaviour modification seems to be quite common in certain parasitical infections: Leucochloridium paradoxum put me off the concept of snails at a very early age.

still i wonder at something so specifically designed for reproduction and nothing else - parasites aren't likely to get intelligent anytime soon.

Hey, you gotta love snails:

"These snails punctuate their mating ritual by puncturing their partners with a calcified "love dart." You could call it a shot in the dark, because the animals can detect light and dark but can't see to aim the tiny "Cupid's arrow." Love darts are strangely common: 17 of the 65 families of terrestrial snails use them."
