Cuttlefish swim and hover using their fluttering side fins, but when they need to make a quick escape they use a water jet below their bodies - you can see these two fighter planes in the photo as they make a quick escape!
The red cuttle is not always red - this series of shots shows the one individual as it changes colour from dark red to lighter mauve. This is one of three cuttle species in Australia; the yellow lining around the eye is diagnostic of the species.
