The Ceram Sea or Seram Sea is one of several small seas between the scattered islands of Indonesia. It is a section of the Pacific Ocean with an area of approximately 12,000 square kilometers located between Buru and Seram, which are two of the islands once called the South Moluccas. These islands are the native habitat of plants long coveted for their use as spices, such as nutmeg, cloves, and black peppercorns, and the seas surrounding them were busy shipping routes. The Ceram Sea is also the habitat of several species of tropical goby and many other fish. Like many other small Indonesian seas, the Ceram Sea is rocky and very tectonically active.
