A dash of colour
We quite frequently bump into fleets of Bigfin Reef Squid (Sepioteuthis lessoniana) while snorkeling in the late afternoon around Lady Elliot Island in Australia. They're funny animals as they're inquisitive enough to approach you but stay just far enough away from you to make them difficult to photograph well. However, with proper lighting and a boatload of patience it's possible to capture their beautiful colouration, which they use for both camouflage and communication with one another.
