    Genel bilgiler

    Mercanlar (Anthozoa), omurgasız hayvanların Knidliler şubesinin denizlerde yaşayan bir sınıfıdır.

    Yumuşak mercanlar, boynuzsu mercanlar, dikenli mercanlar, gerçek mercanlar gibi çeşitleri vardır. Deniz şakayıkları da bu sınıftandır.

    Polip vücutlu bu canlıların mineral maddelerinden karışmış boynuzsu iskeletlerine de mercan denir.

    İlgili gündem

    Türkiye kıyılarında nadir görülen siyah mercan (Savalia savaglia) ve taş mercan (Cladocora caespitosa), deniz ekosistemlerinin en kırılgan canlıları arasında yer alıyor. Yavaş büyüyüp yüzlerce yıl yaşayabilen bu türler, yalnızca biyolojik çeşitlilik değil, deniz yaşamının sürekliliği açısından da büyük önem taşıyor. Ancak müsilaj, iklim değişikliği, deniz dibi tahribatı ve bilinçsiz toplanma gibi tehditler nedeniyle popülasyonları yok olma riskiyle karşı karşıya.
