Has a rather high amount of health compared to other fishes, and does about 300 damage. This enemy has low range, so is very easily defeated using almost any combination of cats. Basically the Sir Seal of the sea, but beware when he becomes more buffed, as then Crab can be a notable threat for underlevelled players.
As mentioned before, this enemy isn't very threatening, so a combination of Macho Cat and/or Wall Cat paired with Sexy Legs Cat and Dragon Cat should take it out easily. Area attackers such as Salon Cat can take groups of them, making her a great choice against it.
