Omnite  

Omanyte, オムナイト

Omanyte is an extinct cephalopod mollusk that resembles an ammonite or nautilus. It has a sky blue body with ten tentacles and a pale yellow, spiraled shell on its back. The rim of the shell contains two circular indents where Omanyte's large saucer-like eyes protrude. When threatened or attacked, it quickly withdraws into its hard shell. Although considered extinct, Omanyte can be revived from fossils. Its fossils have been found 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. It fed on plankton but was preyed upon by Archeops and Carracosta. Due to being released by people or escaping after restoration, Omanyte is now found in the wild, causing it to become a problem species.
