Description

Adult blue triggerfish from the Egyptian Red Sea

Pseudobalistes fuscus can reach a length of 55 centimetres (22 inches) in males. The body is mainly brown, but fins have yellow margins. Juveniles are yellowish brown with a network of brilliant bluish wavy lines. With growth these lines become interconnected. [1]

This fish is known for its aggressiveness and many divers choose to stay away from them, as they bite often.

Distribution

This species is widespread in the Tropical Indo-Pacific, from the Red Sea to South Africa, Society Islands, southern Japan, Australia and New Caledonia. [1]

Habitat

Pseudobalistes fuscus is a reef-associated species. It prefers coastal waters, shallow lagoons and seaward reefs, at 30–50 metres (98–164 ft) of depth. [1]

Diet

This triggerfish, like most other triggerfish, eats shellfish, small crustaceans, and other bottom-dwelling invertebrae. [1]

Triggerfish

Triggerfish are about 40 species of often brightly colored fish of the family Balistidae. Often marked by lines and spots, they inhabit tropical and subtropical oceans throughout the world, with the greatest species richness in the Indo-Pacific. Most are found in relatively shallow, coastal habitats, especially at coral reefs, but a few, such as the oceanic triggerfish, are pelagic. While several species from this family are popular in the marine aquarium trade, they are often notoriously ill-tempered.

Black triggerfish

The black triggerfish or black durgon (Melichthys niger), called Humuhumu'ele'ele in Hawaiian, is a blimp-shaped triggerfish with bright white lines running along its dorsal and anal fins. From distance, it appears to be completely black. However, upon closer inspection with good lighting, one can see that it is actually mottled dark-blue/green coloration often with orange toward the front of the head. Black durgons are capable of changing color based on their surroundings.

Yellowmargin triggerfish

The yellowmargin triggerfish, Pseudobalistes flavimarginatus, are marine fish in the triggerfish family Balistidae. They originate in coastal tropical waters and reefs of the Indo-Pacific from the Red Sea south to Natal, South Africa and east from southern Japan south to Indonesia, Philippines and Samoa. They can be found at water depths from 2–50 m (6.6–164.0 ft).

Reef triggerfish

The reef triggerfish, also known as the rectangular triggerfish, wedgetail triggerfish, or by its Hawaiian name humuhumunukunukuāpuaʻa, also spelled humuhumunukunukuapua'a or just humuhumu for short, is one of several species of triggerfish. It is found at reefs in the Indo-Pacific and is the state fish of Hawaii.

Titan triggerfish

The titan triggerfish, giant triggerfish or moustache triggerfish is a large species of triggerfish found in lagoons and at reefs to depths of 50 m (160 ft) in most of the Indo-Pacific, though it is absent from Hawaii. With a length of up to 75 centimetres (30 in), it is the largest species of triggerfish in its range.

Orange-lined triggerfish

The orange-lined triggerfish is a demersal triggerfish. Although Balistapus is a monotypic genus, it is closely related to the genus Balistoides.

Grey triggerfish

The grey triggerfish or gray triggerfish is a ray-finned fish in the triggerfish family. The species is native to shallow parts of the western Atlantic from Nova Scotia to Argentina and also the eastern Atlantic, the Mediterranean Sea and off Angola on the west coast of Africa.

Gilded triggerfish

The gilded triggerfish or blue-throated triggerfish, Xanthichthys auromarginatus, is a spotted gray triggerfish. Males of the species have blue cheeks and yellow-bordered, white fins. It is widely, but locally, distributed at islands in the Indo-Pacific.

Although most species in the Red Sea pose no threat to humans, there are a few notable exceptions.

<i>Rhinecanthus</i>

Rhinecanthus is a triggerfish genus from the Indo-Pacific. They are found at reefs, and all except R. abyssus are restricted to relatively shallow depths. They are among the smallest members of the family, with no species surpassing 30 centimetres (12 in) in length. They are primarily brownish, greyish and white, and have strongly contrasingly patterns in yellow, orange, blue or black. Adults of all have a relatively dark line that extends from the forehead down through the eye to the pectoral fin.

"Blue-lined triggerfish" can refer to either of 2 species of such fishes:

The stone triggerfish is the largest species of triggerfish. It is found at reefs and over sandy bottoms in the east Pacific, ranging from Baja California (Mexico) to Chile. It can reach 1 metre (3.3 ft) in length, but is more common at about half that size.

<i>Porites lobata</i>

Porites lobata, known by the common name lobe coral, is a species of stony coral in the family Poritidae. It is found growing on coral reefs in tropical parts of the Indian and Pacific Oceans.

<i>Pseudobalistes</i>

Pseudobalistes is a genus of fish belonging to the family Balistidae.

<i>Lethrinus lentjan</i>

Lethrinus lentjan is a species of emperor fish. It has a distinctive blood-red colouration around the margin of the gill covers. It is widespread around the Indo-West Pacific, and is reef-associated. This species is fished commercially and for sport.

The marine wildlife of Baa Atoll consists of marine species living in a circular archipelago in the Maldives, inside the administrative division of Baa Atoll, which is the southern part of Maalhosmadulu Atoll. Baa Atoll was named a biosphere reserve by UNESCO in 2011.

Temple Reef is an artificial reef off the coast of Pondicherry, India. It was constructed of fully recycled materials such as concrete blocks, rocks, trees, palm leaves, and iron bars by the Temple Adventures team starting from October 2013. Temple Reef Foundation currently maintains and monitors the reef.
