One of the most exquisite parts of night diving is watching the coral feeding. Zooplankton rise from the nooks and crannies of the reef and drift past an ocean of mouths that include reef corals, sea anemones, brittle stars, and basket stars. Corals bloom after dark, absorbing nutrients from the water around them and looking truly beautiful. (Photograph:

Cuttlefish are predators and, like many cephalopods, occasionally indulge in a bit of cannibalism. They can change the colour and texture of their skin, disguising themselves as clumps of floating seaweed as they stalk their prey. They hunt from the moment they hatch and even the smallest hatching will succeed in catching its prey four times out of five. They are restricted by water temperature so in years when the seas warm up, their range increases. (Photograph: Mark Snyder)

The Black Ribbon Eel is actually just a juvenile Blue Ribbon Eel. The Ribbon Eel family is quite a colorful lot. The juveniles start out black, then change color in adulthood. The males turn blue and yellow, eventually becoming females and turning yellow or yellow-green later in life. They are relatively peaceful, though they are predators. It is often seen sitting with its mouth open to breathe, frequently mistaken for a predatorial stance.  (Photograph: Anne Lecuire)

Checkerboard wrasses get their name from the terminal phase adult, which is covered in a series of black crosshatches set over a pale blue-green background. This dual close up and distant coloration types simultaneously acts towards camouflage from predators and communication with other checkerboard wrasses at closer quarters.

As the name suggests, this species looks like the calcareous green algae, Halimeda, with which it normally associates. It is green or green with white patches (like those seen on the dyeing algae). The nose is long, the caudal peduncle is narrow and the tail is not incised but more rectangular in shape. (Photograph: Scott W. Michael)
