Coral polyp mouth. Close-up of the mouth (pink,centre) of a hard coral polyp (class Anthozoa). This marine invertebrate uses its tentacles (not clearly seen) to catch plankton from the water,which it then passes to its mouth. The polyp secretes a hard skeleton for protection and support. The vast rock-like reefs produced by colonies of polyps form the basis for diverse marine ecosystems. Photographed off Mantanani,Malaysia | |
