Stunning Squid Pictures
From the giant squid to microscopic squid babies, squids are beautiful and fascinating. As cephalopods, the same family as octopuses and cuttlefish, they have no bones, and swim head-first through the water with their 8 arms (and a pair of tentacles, in some species) trailing behind them. Some squids are brilliantly colored, with the ability to change the color of their skin to communicate, attract a mate, or defend against predators using chromatophores. They swim by jet propulsion, shooting seawater from a funnel, and some squids can even fly out of the water!
