iklis

Iklys is a genus of coral in the family Siderastreidae, comprised of species commonly known as star corals. These marine invertebrates are predominantly found in reef environments across the Indo-Pacific region and the Caribbean. Characterized by their symbiotic relationship with photosynthetic algae called zooxanthellae, iklys play a vital role in reef building and maintenance.

Iklys typically exhibit a calcareous exoskeleton with a distinctive star-shaped pattern of ridges and valleys, which provides structural support and protection. The colonies can vary in size from a few centimeters to over a meter in diameter, forming complex reef structures that serve as habitats for numerous marine species.

These corals are filter feeders, capturing plankton and organic particles from the water, but their primary energy source comes from the photosynthetic activity of their symbiotic algae. They thrive in clear, shallow waters where sunlight penetration is optimal, and they are sensitive to environmental changes such as temperature fluctuations, pollution, and acidification.

Reproduction in iklys occurs through both asexual budding and sexual reproduction via spawning events, during which eggs and sperm are released into the water column. The larval stage then settles onto suitable substrates to form new colonies.

Due to threats posed by climate change, overfishing, and habitat destruction, many ikly species are classified as vulnerable or threatened. Conservation efforts focus on protecting reef habitats, reducing carbon emissions, and establishing marine protected areas to ensure the survival of these ecologically important corals.
