The Helicoprion is a water-dwelling carnivore known for its unique weight-reduction abilities. It reduces the weight of several key resources by -50%, including Metal, Stone, and Crystal. This makes it highly effective for underwater resource transport and deep-sea base hauling operations.
It can carry smaller mounts such as Ankylosaurus or Castoroides in its claws.

Compare recorded corpse resource yields by harvesting tool.
Each harvest event rolls resources independently. Actual yields vary.
Killing a Helicoprion yields Raw Fish Meat and Raw Prime Fish Meat. The Dino (Fish Harvest) tool yields the most Raw Fish Meat, while the Sickle provides the highest quantity of Raw Prime Fish Meat.
While ridden, Helicoprion gathers resources using its BuckFeedResponse attack within a 5m range. It harvests berries, fiber, mushrooms, rare flowers, sap, seeds, and wood. Each resource is gathered at a 10× multiplier, except Cactus Sap and Fiber which yield 8×. This makes it exceptionally efficient for rapid plant-based resource farming.
