They look like eyes buy aren't the eyes the pink things underneath it?
Kabuto is similar to a shellfish with a tan shell. There are two small black dots, which are a second pair of eyes, on the front of its shell. Kabuto uses these eyes when it hides deeper in its shell to protect itself from harm. Its black eyes sense what is going on outside of the shell while it is hiding. Underneath its shell is mostly black, with two red eyes, which glow in the dark, and four yellow-tan legs. Its shell turns into the Fossil that is used to resurrect it.

They're eyes.
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 on its underside.
As you can see by Kabuto's in game sprites their in fact another pair of eyes:

Hope I helped :)
Just random dimples on its shell. >The Red and Blue sprites show that Kabuto has a smooth shell. In subsequent generations, it is shown with dimples in its shell.
