Biology
Omastar uses its tentacles to capture its prey. It is believed that it went extinct because its shell grew too large and heavy, causing its movements to become too slow and clumsy. Once wrapped around its prey, it never lets go as it attacks by tearing into it with the sharp beaks that ring its mouth.
