Red-lined Triggerfish or Orange-lined Triggerfish Balistapus undulatus occurs in the tropical Indo-Pacific from the Red Sea south to Natal, South Africa and east to the Line, Marquesan and Tuamoto Islands, north to southern Japan, south to the southern Great Barrier Reef and New Caledonia in a depth range from 0 to 60m, max. total length 30cm. Adults are territorial in coral-rich areas of deep lagoon and seaward reefs. They feed on a variety of benthic organisms such as algae, echinoderms, fishes, mollusks, tunicates, sponges, and hydrozoans. The caudal peduncle spines of this species are not the sharp, scalpel-like peduncular spines of the Surgeonfishes. Nevertheless it is a traumatogenic species, known to chase and bite intruders with sharp teeth, including divers, especially when guarding a territory. The caudal peduncle spines can deter predators by causing discomfort or minor injury if grabbed near the tail region. The strong jaws and dorsal spine are the primary defense.

Adults of Napoleon Wrasse Cheilinus undulatus develop thick lips and a prominent bulbous hump on the forehead and can grow up to more than 2.2 meters. The species inhabits steep outer reef slopes, channel slopes and lagoon reefs. Primary food are mollusks, fishes, sea urchins, crustaceans and other invertebrates. Napoleon Wrasse is one of the few predators of toxic animals such as sea hares, boxfishes and crown-of-thorns starfish. Napoleon Wrasse is is seriously endangered, being hunted to the brink of extinction to feed a growing demand among wealthy Chinese diners for luxury live fish. Not wise, so crown-of-thorns starfishes take over and destroy the reefs. Palau, Micronesia, 7°8'0.39 N 134°13'12.99 E at 15m depth
