Saccostrea kegaki, the Japanese spiny oyster, is a species of rock oyster in the family Ostreidae.[1]
Description
Saccostrea kegaki is a small encrusting oyster with its shell only reaching a length of 2 to 5 cm. It is characterized by black, dense, pipe-like spines clustered on the right valve and margin of the left valve. The rest of the shell is typically white. Radial ribs and shell plication are not prominent.[2]
Distribution
Saccostrea kegaki is found in western Japan[3], the Korean Peninsula[2], and Taiwan[4].
Ecology
Saccostrea kegaki are often found in middle intertidal rocky shores[3], expect for in standing tide pools.[5]
The pea crab, Pinnotheres boninensis, is a known parasite to the S. kegaki and decreases the oyster's body weight and reproductive abilities.[3]
