Yellowtail Barracuda

Overview

The Yellowtail Barracuda is one of the smaller members of the barracuda family, recognized by its slender, torpedo-shaped body and distinctively yellowish tail. It is a widespread species in the Indo-West Pacific and has successfully expanded its range into the Mediterranean Sea as a Lessepsian migrant via the Suez Canal.

Distribution & habitat

This species is found throughout the tropical Indo-West Pacific, ranging from the Red Sea and East Africa to Samoa, and from southern Japan down to the Great Barrier Reef. It typically inhabits sheltered coastal and lagoon reefs, as well as bays, often remaining in relatively shallow waters.

Appearance

Characterized by an elongated, silvery-green to yellowish body, this barracuda often displays two faint brown or brownish-yellow longitudinal stripes along its flanks, which may fade in older individuals. It features a large head with a pointed snout, a projecting lower jaw, and a forked caudal fin that is notably yellow with dark margins. Its two dorsal fins are well-separated, and it possesses a prominent membranous flap at the corner of its preopercle.

Biology & behavior

Yellowtail Barracuda are schooling fish that often congregate in dense, shimmering groups during the day for protection. While they appear relatively inactive while schooling in sheltered reef areas, they are efficient and active predators. Their life cycle involves planktonic eggs and larvae, and they are known to reach maturity at a relatively small size.

Feeding

As active predators, they primarily hunt for smaller fish and various invertebrates, including cephalopods and crustaceans. While they school for safety during daylight hours, they are known to be more active hunters at night.
