Sand shark

The sandshark is a large animal that burrows underground in the Si Wong Desert.

Anatomy
This gigantic creature is about the size of a blue whale. it is primarily brown, with a beige belly and beige webbing on it's dorsal fin. It has six fins on its belly, two large brown ones in front and four smalller beige ones near it's back. The dorsal fin runs nearly the entire lenght of the animal, with a peak in the middle. The animal has multiple rows of teeth, three rows in both it upper and lower jaw, and a group of teeth in each cheek.

Behavior
In the wild, this creature can be quite agressive. It attacked an Earth Kingdom airship and it kept attacking another vessel while the occupants were trying to make their escape. It moves itself mostly by burrowing underground in the loose sand of the desert. Typically low enough to keep itself from being visible, but when the animal is chasing a prey, it can have it's dorsal fin sticking out above the sand. It hunts mostly by surprise, suddenly appearing underneath its prey.

Connection
It mostly bears a resemblance to a great white shark, with the main altorations being its size and color. It's hunting style also bears a resemblance to sharks, as do its multiple rows of teeth.
