Sand shark

A powerful, medium-sized predator that burrows into the sand and ambushes its prey from below. As with many predators it may be possible to temporarily distract sand sharks by feeding any hungry specimens that draw close.

1. Forward Dorsal Fin

The unusual location of this fin suggests a purpose unrelated to movement through the water. It may be employed in shifting sand beneath the surface, or in mating rituals, or may simply be an evolutionary dead end.

2. Segmented Exoskeleton

Thick armor plating renders the sand shark almost immune to attack from above. While it is capable of impressive acceleration its exoskeleton prevents it from changing direction quickly. The sand shark is thus a perfectly-designed ambush hunter, but ill-suited to sustained pursuits.

3. Feet

Ill-designed for ambulation. Likely used to disturb the surface of the sand so the lifeform can burrow into the ground. Assessment: Avoid - Be vigilant for ambush in sandy biomes
