Bluespotted Cornetfish

Overview

The Bluespotted Cornetfish is a highly distinctive, elongated marine fish known for its slender, whip-like body and long, tubular snout. Widely distributed across tropical and subtropical Indo-Pacific waters, it has also become a successful invasive species in the Mediterranean Sea following its migration through the Suez Canal.

Appearance

This species features a smooth, scaleless body that is slightly flattened from top to bottom. Its coloration typically ranges from grey to olive-green or brown on the back, fading to a silvery-white belly, often accented with blue spots or stripes. A key identifying feature is its forked tail, which includes a very long, thin central filament that contains sensory pores to help detect prey. Unlike the related Red Cornetfish, it lacks bony plates along the midline of its back.

Biology & behavior

Bluespotted Cornetfish are benthopelagic, often found hovering near rocky reefs, seagrass beds, or sandy bottoms. They may be seen swimming alone or in small groups. When resting near the seafloor, they can display dark, vertical stripes for camouflage. They are active, efficient swimmers and are considered voracious predators within their environment.

Feeding

As a skilled carnivore, this fish primarily hunts small schooling fish, though its diet also includes crustaceans and squid. It often employs an ambush strategy, using its streamlined shape and speed to strike at prey with precision. Its long, tubular mouth acts like a pipette to suction up smaller organisms.
