Cuttlefish and the wonders thereof

i've long been fascinated by these strange creatures and recently my wife adn i caught an amazing show about cuttlefish, which demonstrated amongst other things that they were the smartest of the cephalopods (and i love that that's greek for 'head-foot'!), when previously octopuses were thought to have been the nerds of the species. they have this awesome ability to change colour, and even to put on bizarre 'light shows' to dazzle their prey and also for attracting a mate - but it's just the males who do the prancing, ala peacocks.

here's another, smaller video which shows a 'light show' used in hunting (off Irian Jaya).
