This article is about the Boneshark. You may be looking for the Sand Shark.

The Boneshark is a large, highly aggressive fauna species. It is an actively fierce predator and mainly dwells in the Underwater Islands, Crag Field and Bulb Zone biomes.

Appearance Edit

The Boneshark is a large creature with a body entirely plated with bone and a large head featuring spikes extending backwards. Its head features a large mouth full of small, sharp teeth, which rather than normal teeth that are set into gums, are an extension of the exoskeleton, and two bioluminescent green eyes. It lacks a dorsal fin but has two spiked pectoral fins and flukes at the end of its tail. It is grey in color, with orange patterns on its head and to the edges of each bone plate.

Behavior Edit

The Boneshark is carnivorous, so one can be seen chasing other smaller fish, such as the Peeper. It is highly aggressive, often going so far as to attack members of its own species. Once the player is spotted, it will charge at them while screeching. Bonesharks are rather fast and are more than capable of catching up to the player. To avoid them, swim in a circular motion until the creature loses interest or get into a submersible. The Repulsion Cannon is also an effective tool to fend them off. The Boneshark's bite deals 30 damage to the player. It deals less damage to submersibles, but is still a threat. Bonesharks are also attracted to lights. Because of this, the creature can also be distracted using Flares or by using a Creature Decoy. When Bonesharks are attacked, they will turn to face their attacker and attack back, usually causing the attacker to flee.


Spoiler alert: The following section contains story related material.


The Bonesharks inside Primary Containment Facility's Aquarium are not hostile to the player, and are thus not a threat.

Trivia Edit

  • The Sea Emperor Leviathan and the River Prowler previously used the AI of the Boneshark.
  • Bonesharks once dwelled in large numbers in the Grassy Plateaus.
  • Through a mistake, Bonesharks were incorrectly scaled and around half the size they were intended to be for the majority of the early access phase of Subnautica. This was fixed in the Voice of the Deep Update of 2017, where they were given a 50% size increase, then an additional 10% size increase on top of that.
  • The Boneshark, along with the Lava Lizard and River Prowler, use to be aggressive to the Cyclops and were capable of damaging the submersible.
