Very rare in Vanuatu. SIZE May exceed 7 metres but usually much less. M male length 4.2 to 4.8m. A carnivorous species and a largely opportunistic feeder. In juveniles small fish are taken but crustaceans and insects comprise the main part of the diet.
Larger juveniles take more vertebrate prey.
Food items include sharks, archer fish, barramundi and mangrove snakes. Riverine birds and mammals may also be taken. As size increases an individual become able to deal with progressively larger prey such as turtles, cattle, horses and humans. Virtually any mammal at the water's edge will be attacked. They are mainly shallow water or edge feeders.
