i saw a documentary (TV) that had film of a snail infected with a similar
parasite (or same) that grew inside the snail and migrated to the eye stalks
(that would swell with the parasite inside) where it would acutally pulsate
with amazing colours and rythem (it would flash bands of yellow on red that
started @ the bottom of the stalk and flashed to the top), it was a pretty
impressive animated display, it attracted birds who would eat either the
whole snail or just the eye stalks.
