Squids

When one imagines a squid, the image that comes to mind is of a giant monster (i.e, Kraken of mythic fame) grappling with boats and whales. Squid are marine cephalopods of the order Teuthida, which comprises around 300 species. Like all other cephalopods, squid have a distinct head, bilateral symmetry, a mantle, and arms. Squid, like cuttlefish, have eight arms arranged in pairs and two, usually longer, tentacles. Squid are strong swimmers and certain species can 'fly' for short distances out of the water. Some are giant and some are tenaciously small. An expedition to the seamounts of the southern Indian Ocean has proven that the region is a biodiverse hotspot for squids. To date, the expedition has identified 70 species of squid comprising 20% of the world's known squid species. But that's not all: they have also uncovered new species.
