Interesting Marine Life

The stars of this site are sea slugs, which are abundant both in numbers and in diversity, which has been recorded of more than 70 species, ranging from the common nudibranchs such as Jorunna funebris and Doriprismatica atromarginata to other rarer species such as Platydoris ellioti.

At the tip of the north cape, there is an underwater wall that is home to a beautiful species of sea slug named Phyllodesmium magnum. Look for their soft coral prey and you may find them.

In the middle of the bay around the scattered rocks, you may find other creatures such as cuttlefish or stingrays.

Other animals in the area include toadfish, stonefish, clownfish, and occasionally a hawksbill sea turtle.
