Omanyte

Omanyte is a dual-type Rock/Water Fossil Pokémon.

It is resurrected from a Helix Fossil and evolves into Omastar starting at level 40.

Biology
Omanyte is a small Pokémon similar to an ammonite. It has a sky blue body with ten tentacles and a pale yellow, helix-spiraled shell on its back. The shell's rim has two circular indents where Omanyte's large saucer-like eyes protrude. If attacked or threatened, it quickly withdraws into its hard shell.

Omanyte is considered extinct, although it can be revived from Fossil. Its fossils have been excavated in areas that were once oceans long ago. Omanyte regulated its buoyancy by storing and releasing air within its shell and controlled direction by twisting its tentacles. While Omanyte fed on plankton, it was preyed on by Archeops and Carracosta. Omantye can now be found in the wild due to being released by people or escaping after being restored back to life, causing this species to become a problem.
