As we gear up for Discovery Channel's Shark Week, let's not completely forget about our favourite invertebrate group: the cephalopods! Marine scientists around the world have dedicated this week to celebrating squid, octopuses and their relatives – and the team at Monterey Bay Research Institute (MBARI) is joining in on the fun. 

This amazing video shows a deep-sea squid in the genus Taonius. These strange, transparent animals are typically found 300 metres (900ft) below the surface, floating in the 'cockatoo position' (with their arms up as we see here). Taonius squid are easily recognised by their large, front-facing eyes, which can rotate in different directions to locate prey (and to judge you from any angle, of course).
