Palaeoctopus is a water-dwelling carnivore known for its unique role in underwater resource gathering. It is carried by Tusoteuthis, allowing it to be transported aerially for strategic deployment. This makes it ideal for players needing efficient underwater Bio Toxin and chitin collection while benefiting from mobile support.

Palaeoctopus must be knocked out to tame. The most effective food is Black Pearl, which provides the highest affinity. Raw Mutton also works, though less efficiently. Use a Bow or Crossbow with Tranq Arrows to sedate it. Immobilize it first with a Chain Bola or Bear Trap. The process takes around 38 minutes with 84 Black Pearls.

Compare recorded corpse resource yields by harvesting tool.
Each harvest event rolls resources independently. Actual yields vary.
Killing a Palaeoctopus yields Absorbent Substrate, Black Pearl, Hide, and Raw Meat. The Hatchet harvests the most Hide, while the Pick yields the highest amount of Raw Meat.
While ridden, Palaeoctopus excels at harvesting Bio Toxin, Chitin, Keratin, Raw Fish Meat, and Raw Prime Fish Meat. Its Blast attack gathers these resources at up to 3× efficiency. All tentacle-based attacks contribute to gathering, making it highly effective in aquatic environments.

Palaeoctopus takes +400% more damage from spike walls, making it highly vulnerable to defensive setups using them. It is also weak to instant damage sources, taking +120% more damage. However, it is fully resistant to Mining Drill Harvest damage. Focus on Health and Melee Damage for survivability.
The head has a 1.5× damage multiplier, making headshots effective for faster knockouts. Target this zone when sedating the creature.
The Blast attack gathers Bio Toxin at 3× efficiency, making it ideal for farming.
All tentacle attacks yield double resources from chitin and prime meat nodes.
It can be carried by Tusoteuthis, enabling aerial transport during operations.
While being carried, it retains full functionality for underwater harvesting.
Its high vulnerability to spike walls means it should never be used in direct combat near such defenses.
This page details the Palaeoctopus's taming, breeding, harvesting, weight reduction, and combat data. For precise calculations, refer to the taming calculator and spawn map tools available on-site.
