Sand Shark
A swift, sandy predator that guards the shallow reefs of Planet 4546B.
Sand sharks are mackerel sharks of the family Odontaspididae. They are found worldwide in temperate and tropical waters. The family contains two species in a single extant genus (Odontaspis), as well as several extinct genera. The body tends to be brown with dark markings in the upper half. These markings disappear as they mature. Their needle-like teeth are highly adapted for impaling fish, their main prey. Their teeth are long, narrow, and very sharp with smooth edges, with one and on occasion two smaller cusplets on either side. Sand sharks have a large second dorsal fin.

Lore & Background
Despite being a common sight, the Sand Shark plays a crucial role in the survival loop of the planet's ecosystem. They are often seen patrolling the perimeter of kelp forests and shallow trenches. While they generally avoid larger predators like the Reaper Leviathan or Ghost Leviathan, they will aggressively defend their territory if threatened by divers or if food is scarce. Their presence indicates a healthy, albeit dangerous, food web in the upper layers of the ocean.
In Their Own Story
The water was clear and sun-dappled as I descended toward the sandy floor, my Rebreather humming softly. Suddenly, a shadow flickered against the grains below—a sleek, beige shape darting with terrifying speed. It circled me once, its dark eye unblinking, before snapping at a nearby Reef Crab. The Sand Shark was a reminder that even in the gentle shallows, nature here is ruthless and hungry.
Reader's Guide
The Sand Shark possesses a streamlined, torpedo-like body covered in rough, sand-colored scales that blend seamlessly with the ocean floor. It features a prominent dorsal fin, pectoral fins for steering, and a powerful tail used for rapid bursts of speed. As a carnivore, it primarily hunts Reef Crabs and small fish found in shallow biomes like the Shallows and Kelp Forests. While generally neutral to divers who ignore them, they become highly aggressive if provoked, attacked, or if the player enters their personal space while holding food items. Players can harvest Sand Shark Meat and Scales using a Knife or Seamoth Drill Arm after killing one. These resources are essential for crafting early-game equipment like the Prawn Suit's drill arm upgrades or creating food. Unlike some larger fauna, they cannot be tamed but can be lured with bait to clear specific areas.
Did You Know?
- Sand sharks are not known to attack humans. If a person were to provoke a sand shark, it may retaliate defensively.
- Sand sharks only develop two embryos, one in each uterus. The largest and strongest embryos consume their siblings in the womb (intrauterine cannibalism) before each surviving pup is born.
- It has one of the lowest reproduction rates of all sharks and is susceptible to even minimal population pressure, so it is listed as vulnerable and is protected in much of its range.
- The sand shark has a unique hunting strategy. It is able to gulp air from above the surface and collect the air in its stomach. This enables it to become buoyant and approach its prey virtually motionless.
- The name sand shark comes from their tendency to migrate toward shoreline habitats, and they are often seen swimming around the ocean floor in the surf zone; at times, they come very close to shore.
