Here you will find fish with body armour, shy fish that hide at the first sign of danger, fish that can puff themselves up like a ballon, to aggressive parents with massive crushing teeth.

Boxfish



This is the only fish group that has a carapace of bony plates that functions as body armour. Cowfish have a pair of foward-pointing sharp horns above the eyes. Some species produce a skin toxin, ostracitoxin, that is and additional deterrent to predators.

They are shy, slow swimmers, that can put on a spurt of speed at need.

The males and females of some species have differing colours and patterning. The juveniles of other species can look totally different from the adults. The gray-blue Yellow Boxfish (Ostracion cubicus) with its' bright yellow juvenile stage is the best known by divers.

Filefish



Closely related to triggerfish, the tend to be thinner and many can change colour to match their surroundings. There are species that mimic poisonous pufferfish, species that are coral polyp specialists, and tiny species that hide between soft coral branches .

They are generally solitary, shy slow swimmers that like pufferfish, can put on a spurt of speed.

Pufferfish



Pufferfish are shy reef-dwellers with two forms of protectiion. Under the threat, they can inflate themselves with water to several times their original size. In addition, the highly toxic poision tetrodtoxin accumulates in varying quantities in their livers and ovaries.

Generally they are solitary or in small groups.Bennetts Toby (Canthigaster bennetti) is one that can be seen in small groiups, It is shown below in mating colours.

Once every few years, a rocky underwater hill near Una Una, a tiny island in the middle of Tomini Bay, North Sulawesi, is home to an amazing spectacle. Dead & dying tobies litter the surface, the surface of corals and fill up Barrel Sponges. The water is a soup of tobies, while millions aggregate around the hill.

The aggregation photo was taken early April, 5 days after a new moon.

Triggerfish



Anyone who thinks that sharks are dangerous has never had a run in with Titan or Ocean Triggers in the nesting season! They are even more aggressive than anenome fish, and have large, impressive, crushing teeth, as can be seen in the "dental portraits". Their nesting territory is conical, widening as you ascend,

They are generally solitary and fairly shy, though Red-Toothed Triggers (Odonus niger), which are bright blue, can occur in large aggregations along drop-offs. In remote areas that are rarely visited or fished, the larger triggers will ignore divers.

Help Save Reefs!



The organisations that work to protect coral reefs and our oceans need as much support as they can get. Check out:

If you are a diver, and especially if you are an underwater photographer, donate. If you do nothing, there will be nothing to dive on and nothing to photograph.

These are suggestions, but not endorsements of the suggested organisations. It is your responsibility to review and check the charities you wish to donate to.
