The Dunkleosteus is a large carnivorous fish tamed for its exceptional resource gathering and weight reduction abilities. It reduces the weight of several key resources, making it ideal for underwater mining and transport. Players typically tame it to harvest valuable materials like Oil and Metal efficiently while reducing inventory load. Its weight reduction applies to Crystal, Obsidian, and Black Pearl, enhancing its value in deep-sea operations.

Tame a Dunkleosteus using the knockout method. Superior Kibble is the best food, providing the fastest taming effectiveness. Raw Mutton also works well if kibble is unavailable. Use Tranq Arrows from a Bow or Crossbow, or a Longneck Rifle with Tranquilizer Darts to sedate it. The process takes about 40 minutes and requires no Narcotics. Use the calculator below for your settings.

The Dunkleosteus reduces weight by -50% for Oil, Metal, Stone, Crystal, and Black Pearl, and by -75% for Obsidian. Pair it with a carrier like Quetzal to maintain these reductions during aerial transport.
Compare recorded corpse resource yields by harvesting tool.
Each harvest event rolls resources independently. Actual yields vary.
Killing a Dunkleosteus yields Raw Fish Meat, Chitin, and Raw Prime Fish Meat. The Mining Drill extracts the most Raw Fish Meat from the corpse.
While ridden, the Dunkleosteus gathers a wide range of resources through its attack, including Blue Gem, Cementing Paste, Condensed Gas, Crystal, Electronics, Element Dust, Element Ore, Flint, Fragmented Green Gem, Green Gem, Metal, Obsidian, Oil, Organic Polymer, Rare Mushroom, and Sand. It excels at harvesting multiple high-tier resources in one location, especially in deep ocean biomes.

Dunkleosteus takes +400% more damage from spike walls, making it highly vulnerable in defensive setups. It is also weak to explosions and melee attacks from metal weapons. Conversely, it is fully immune to damage from Mining Drill harvesting and has strong resistance to engine-based and ranged turret attacks. Focus on spike wall traps for effective defense.
The head is the most vulnerable hitbox zone, taking 1.5× damage. Target the head for faster knockouts during taming or combat.
Can break Thatch, Stone, and Wood structures. Build at least in Metal to resist its attacks.

The Dunkleosteus harvests nine times the normal amount of Blue Gem and Oil per attack. It reduces the weight of Obsidian by -75%, the highest reduction among all resources. Its attack gathers from categories including gems, metal, oil, and polymer, making it one of the most versatile underwater gatherers. It is highly vulnerable to spike walls, so avoid placing it near such defenses when used in combat.
