Pervagor

Pervagor is a genus of pufferfish in the family Tetraodontidae. They are commonly known as “sharpnose pufferfish” or “trumpetfish”. The genus currently contains 11 species, all of which are found in the tropical and subtropical waters of the Indo-Pacific region. These pufferfish are known for their distinctive sharp snouts and elongated bodies, giving them a trumpet-like appearance.

Characteristics

Pervagor species are relatively small pufferfish, with most species reaching a maximum length of around 20 centimeters (8 inches). They have a unique elongated body shape and a sharp, pointed snout that is used for foraging in crevices and amongst coral reefs. Their bodies are typically covered in small, spiny scales, giving them a rough texture. Pervagor species are also known for their ability to inflate their bodies with water when threatened, making them appear much larger and deterring potential predators.

Environment

Pervagor pufferfish are primarily found in shallow, tropical and subtropical waters, often associated with coral reefs, rocky shores, and seagrass beds. They prefer habitats with ample cover and a variety of food sources. They are generally solitary fish, but may occasionally be found in small groups.

Diet

Pervagor pufferfish are carnivorous and primarily feed on a variety of invertebrates, including crustaceans, mollusks, and worms. They use their sharp snouts to probe crevices and pry open shells, accessing their prey. Their diet can also include algae and plant matter.

Reproduction

Pervagor species are thought to be oviparous, meaning they lay eggs. However, the details of their reproductive behavior and spawning habits are not well understood.
