They are also known as Balloonfish.  These fish are known to be very friendly with and curious of scuba divers.  Image taken whilst scuba diving in the Andaman Sea, Thailand.

Titan Triggerfish Balistoides viridescens occurs in the tropical Indo-Pacific Ocean from the Red Sea and East Africa eastward through northern Australia reaching to Line and Tuamotu islands, north to southern Japan in a depth range from 1-50m , max length 75cm. The distinct pairing species, the largest triggerfish species, is encountered in lagoons, seaward reefs and sheltered inner reef slopes. There are reports of ciguatera poisoning. Ciguatera, a foodborn illness, caused by bioaccumulation, a very heat-resistant toxicity, cannot be detoxified by conventional cooking. Titan Triggerfishes are often hostile towards divers and may attack unprovoked when caring for eggs. They feed on sea urchins, coral, crabs and other crustaceans, mollusks and tube worms. This specimen was hiding in a niche of a vertical wall at 9m depth by night. Palau 7°4'59.15 N 134°15'44.16 E

Dried Puffer Fish. Porcupine fish have the ability to inflate their body by swallowing water (or air) and become round like a ball. This increase in size (almost double vertically) reduces the range of potential predators to those with much bigger mouths. A second defense mechanism is provided by the sharp spines, which radiate outwards when the fish is inflated.
