Tree-like Finger Leather Coral (Sinularia or Nepthea Coral) – Phu Quoc Coral Species Information

Finger Leather Coral(Sinularia or Nepthea Coral) in Phu Quoc Island, Vietnam

Sinularia is a genus of soft coral in the family Alcyoniidae. They are commonly known as leather corals and currently have 166 described species in the genus.

In the Phu Quoc Half-moon Reef, we can also observe an uncommon soft coral in Phu Quoc is Tree-like Finger Leather Coral (Sinularia or Nepthea Coral), it is usually found at the depth of more than 8 – 12 m but we found some at the depth of around 4 – 5m. The photos of the Finger Leather Coral or Tree-like Leather Coral below were captured at the Half-moon Reef, Phu Quoc Island, Vietnam. It’s not common to see this coral species in Phu Quoc Island.

Sinularia will periodically retract its polyps and form a waxy film that is why sometimes we found it white resembles coral bleaching. This shrunken state may last a couple weeks before the film is shed and the polyps re-extend. We believe this shedding is a healthy process that Sinularia employs to prevent nuisance algae from growing on it. This process can be aided by greater circulation around the coral.
