Dogtooth tuna are apex pelagic predators that use the Late Island wall as an ambush point, stationing themselves in the blue water off the drop-off and accelerating into baitfish schools with explosive bursts of speed. Their mass — regularly exceeding 60 kg — and the frequency of encounters at Late make this one of the most reliable sites for this species in the Tongan archipelago.
