Leptastrea bewickensis, commonly known as Stony Coral, is a species of coral found in tropical and subtropical waters. It is a small, colonial coral that forms rounded, massive colonies. Stony Coral is a crucial part of the coral reef ecosystem, providing habitat and food for a variety of marine organisms.
Description & Characteristics
Leptastrea bewickensis is a small, colonial coral that forms rounded, massive colonies. The colonies can grow up to 30 centimeters in diameter. The coral polyps are small and have a diameter of about 1 centimeter. The polyps are covered in a layer of tissue called the coenosarc. The coenosarc is what connects the individual polyps together and gives the colony its shape.
Leptastrea bewickensis has a distinctive appearance. It is usually a pale gray or brown color, but can also be reddish or yellowish. The coral has a smooth surface and is covered in small, raised bumps called corallites. The corallites are the openings where the polyps live.
Habitat and Occurrence
Leptastrea bewickensis is found in the Indo-Pacific region, including the Red Sea, the Indian Ocean, and the Pacific Ocean. It is typically found in shallow, clear water in reef environments. It prefers areas with a strong current and is often found growing on rocks, dead corals, and other hard substrates. It is usually found in depths ranging from 1 to 30 meters.
Leptastrea bewickensis is an important part of the reef ecosystem in the tropical and subtropical marine zones, which is characterized by warm waters and abundant sunlight.
Taxonomy
Leptastrea bewickensis belongs to the Class: Hexacorallia, Order: Scleractinia, and Family: Leptastreidae. This classification indicates its position within the animal kingdom. It is a stony coral belonging to the subclass Hexacorallia, which encompasses a wide array of corals, anemones, and jellyfish. Further categorization places it within the Order Scleractinia, a group of corals known for their hard, calcium carbonate skeletons. Lastly, it belongs to the Family Leptastreidae, which includes various species of stony corals often found in reef ecosystems.
Feeding
Leptastrea bewickensis feeds on plankton, tiny organisms that drift in the water. The polyps capture plankton using their tentacles, which are covered in stinging cells called nematocysts. The nematocysts paralyze the plankton, allowing the polyps to ingest them. They also have a symbiotic relationship with zooxanthellae, single-celled algae that live within their tissues. These algae provide the coral with food through photosynthesis, using sunlight to convert carbon dioxide and water into sugars that the coral can utilize. In return, the coral provides the algae with a safe and protected environment to live in.
