RED-SPOT NIGHT OCTOPUS, OCTOPUS DIERYTHRAEUS
On a night snorkel in the Whitsundays, I witnessed a range of cephalopods taking advantage of the cover of darkness, such as this red-spot night octopus. This particular individual was hovering above the reef trying to catch shrimp using a range of amazing hunting displays as seen in this image.
