Endangered Species of the Week: Floreana coral

Floreana coral

Floreana coral (Tubastraea floreana)

Species: Floreana coral (Tubastraea floreana)

Status: Critically Endangered (CR)

Interesting Fact: The polyps of Floreana coral are bright pink in the water, and dark red-black when dry.

More information:

Found in the Galápagos, Floreana coral is a scleractinian coral, which means that it is a hard coral with a limestone skeleton.  Floreana coral is known as an ‘azooxanthellate’ coral, as this species does not have zooxanthellae, the algae that live inside the tissues of some corals and provide the corals with food. Corals without zooxanthellae instead feed on zooplankton, capturing these tiny aquatic animals in their outstretched tentacles. Floreana coral can be found on ledges, overhangs and the ceilings of caves, at depths of between 2 and 46 metres.

Now classified as Critically Endangered (CR) on the IUCN Red List, and listed on Appendix II of CITES, the Floreana coral is thought to have once been fairly widespread around the Galápagos Islands. However, since the El Niño event of 1982-1983, this coral has only been seen at Cousins Rocks and Gardner Islet. Despite searches specifically for this species, the Floreana coral has not been seen at Cousins Rocks since 2001. This indicates that any alterations to the water temperatures surrounding the Galápagos Islands are likely to threaten this coral and cause further mortality.

The unique biodiversity of the Galápagos Islands and the surrounding waters is recognised and valued, and the region is protected by being designated a Marine Reserve and World Heritage Site. Any international trade involving the Floreana coral is carefully regulated thanks to CITES. Unfortunately, neither of these measures protects this Critically Endangered coral from the threats of natural, or man-induced, climate change.
