Tabitha is a member of the Hammerhead Clan and the wife of King Shark through an arranged marrige.
She was arranged to marry King Shark in order to keep the peace in the Shark Kingdom and save the Oceanic Trade Federation from crumbling, preventing a war between the clans. However, Nanaue didn't want to get married and left the ocean before it could happen. He first met Tabitha in "Bachelorette" when he returned to the Shark Kingdom and was shocked to learn Tabitha had no interest of marrying him either. He initially stood up to his dad, Shark God, telling him he would not go through with the wedding. However, he soon returned and he and Tabitha agreed to stay married publically but would be allowed to have secret relationships.
- Despite living underwater she is a chain smoker.
