Abalistes
Abalistes is a genus of triggerfish in the family Balistidae. They are commonly known as triggerfish or filefish. These fish are characterized by their unique body shape and their powerful jaws. Their bodies are compressed and deep, with a prominent dorsal fin that can be raised and locked in place, giving them their name. They have strong teeth that they use to crush hard-shelled prey, such as shellfish and crustaceans.
Characteristics
Abalistes species share several key features:
- Compressed, deep body: Their bodies are laterally flattened, giving them a distinctive profile.
- Large, prominent dorsal fin: The first three spines of the dorsal fin are particularly large and can be locked in place, allowing the fish to wedge itself into crevices or against rocks.
- Powerful jaws and strong teeth: They have strong jaws and robust teeth, which they use to crush hard-shelled prey.
- Scales: Their bodies are covered in rough, bony scales.
- Coloration: Abalistes species exhibit a wide range of colors, including browns, yellows, greens, and blues.
Environments
Abalistes species are found in tropical and subtropical waters around the world. They inhabit coral reefs, rocky shores, and seagrass beds. These fish are typically found in shallow waters, but some species can be found at depths of up to 100 meters.

- Abalistes stellatus (Starry triggerfish)
