Kabuto

Kabuto is a small Pokémon with a large brown shell covering its body. There are two small eyes facing upwards on the outside of its shell, which it uses for sight when it hides on the ocean floor. The structure of its body is almost entirely unknown, except its four short, yellow legs and luminescent red eyes found on its underside. Isolated populations of Kabuto have been found to be unchanged for 300 million years. However, most living Kabuto are resurrected from Dome Fossils. In its original time, it was prominently found on beaches, likely aided by its fast and powerful swimming ability. As seen in the anime, Kabuto prefer seclusion and can be very territorial. It protects itself with its stiff shell.
