Tuna: Dogtooth Tuna

Dogtooth Tuna (Gymnosarda unicolor) are large, fast-swimming pelagic predatory fish found around coral reefs and steep oceanic drop-offs throughout the Indo-Pacific region. Highly prized by anglers for their extraordinary strength and speed, they are regarded as one of the most challenging tropical game fish to catch.

Dogtooth Tuna can be recognized by their streamlined torpedo-shaped body, brilliant bluish-black back, silvery belly and large conical teeth from which they derive their common name. They also possess a distinctive wavy lateral line and whitish tips on their soft dorsal and anal fins. Unlike most tuna species, they are strongly associated with reefs and are commonly found near underwater pinnacles, seamounts and deep reef slopes.

They are powerful apex predators that feed primarily on schooling fishes and squids. Dogtooth Tuna are capable of blistering runs immediately after being hooked and are notorious for diving rapidly towards reef structures, making them a favourite target among offshore sport anglers.

Dogtooth Tuna are widely distributed from the Red Sea and East Africa to French Polynesia, north to Japan and south to Australia. They can grow to more than 2 meters in length and weigh over 100 kg. Unlike most tuna species, their flesh is white rather than deep red and is highly valued for sashimi and other seafood dishes. Their exceptional fighting ability, impressive size and eating qualities make them one of the most prized tropical game fishes among offshore anglers.
