Giant oysters look just like ordinary ones, except that they are six feet in diameter and stand four feet high. They may be found in nearly any type of watery environment, although they are most often found in cold, shallow water.
While giant oysters do not collect treasure, they do produce large pearls and occasionally sift other uncut gems from the sea bed.
Giant oysters are usually non-aggressive, but if hungry may snap at nearby creatures. They are protected by an extremely hard shell and the oyster may close up to increase its protection. When closed, a giant oyster may not attack. A giant oyster may close its shell when it bites a foe- effectively starting a grapple. When attacked from a distance, a giant oyster closes its shell and does not open for at least 10 minutes.
Improved Grab (Ex)): To use this ability, a giant oyster must hit with its bite attack. It can then attempt to start a grapple as a free action without provoking an attack of opportunity. If the grapple is successful, the giant oyster maintains a hold on the creature and can inflict bite damage automatically each round. This grappling closes the giant oyster's shell.
Tremorsense (Ex): A giant oyster is sensitive to vibrations in the ground and water and can automatically pinpoint the location of anything within 60ft.
