Sabellaria anglica, Print, Sabellaria is a genus of marine polychaete worms in the family Sabellariidae. The type species is Sabellaria alveolata (Linnaeus, 1767). These worms are sedentary and build tubes in which to live from sand and shell fragments. Some species are called honeycomb worms and when they occur in great numbers they can form reefs on rocks and other hard substrates. They are filter feeders, extending a plume-like fan of radioles from the end of the tube in order to catch plankton and detritus floating past. They have a distinctive operculum which is used to block the opening Stock Photo

Sea corals living underwater can be easily seen through the glass sides of an aquarium at the Mote Marine Laboratory, a popular tourist attraction in Sarasota, Florida, USA. Corals are soft-bodied organisms, called polyps, that grow over many years on a skeleton of hard, protective limestone to form coral reefs that support many types of marine life. These invertebrate animals are often found in shallow tropical waters where sunlight photosynthesizes algae hosted by the polyps and provides nutrients to the coral. Global warming and pollution are ongoing threats to coral reefs around the world. Stock Photo

This is a flathead lobster (Thenus orientalis: 20 cms.); also called a slipper lobster. It can be found on sandy or muddy substrates adjacent to coral reefs in the Indo-West Pacific region. These crustaceans are highly prized as food by humans, who often refer to them incorrectly as crayfish. The eyes are at the margin of the thick carapace and two large antennae project upwards. The thoracic appendages take the form of robust legs. The species is said to have interesting pre-copulatory courtship rituals which, sadly, I have never had the privilege of witnessing.

A reef is a ridge of material at or near the surface of the ocean. Reefs can occur naturally. Natural reefs are made of rocks or the skeletons of small animals called corals. Reefs can also be artificial—created by human beings. Coral reefs begin to form when free-swimming coral larvae attach to submerged rocks or other hard surfaces along the edges of islands or continents. As the corals grow and expand, reefs take on one of three major characteristic structures — fringing, barrier or atoll. Stock Photo

Colonies of this hard stony green coral (Monastrea annuligera: each polyp 2 cms.) can form sizeable boulders. It used to be seen quite frequently in tropical reefs in many parts of the world. However, it has suffered significant population reduction during the last twenty years, mainly because of reef degradation due to pollution and the effects of global warming - but also because it is considered particularly beautiful and so is harvested for the aquarium trade. The IUCN Red List indicates that it is a near threatened species. Photographed off Hurghada in the Egyptian Red Sea. Stock Photo
