Sarcophyton glaucum, also known as toadstool leather coral or rough leather coral, is a common species of soft coral found in Phu Quoc Island, especially at Northeast Coral Reef, U-Turn, Shallow Reef and Half-moon Reef. Toadstool corals resemble or form like a bowl with wrinkles at the mouth, coral has small tentacles that move with the water. The average depths we find them is 1 – 4m, we found a very large toadstool leather coral garden at Shallow Reef in the depth of just 0.5 – 0.6m.
From our observations of the toadstool leather corals in Phu Quoc, we realize that they bleach seasonally, turn into white when tiny polyps (tentacles) are absent or retreat then turn back into yellow color when polyps extend.
Note: No touching, collecting corals (live or dead) and pay attention to your fins (especially in the shallow waters) as some experienced divers can also damage corals by accident with their fin
