Magnificent Kusu Island – an urban reef

Date February 4, 2014

Hantu Blog volunteers made a visit to Kusu Island on 26 Jan to explore more of Singapore’s marine life! We had to set out at dawn to catch the best tide for the dive. We got to catch a beautiful sunrise as we departed the mainland.

Diving off of Kusu Island, we get a view of Singapore’s Central Business District on a clear day!

Kusu Island has so many gorgeous and huge sea fans and loooong sea whips! These simple looking, and somewhat 2-dimensional corals are bursting with so much sea life that has adapted to blend in with the coral and remain completely hidden.

This shrimp on a colony of whip coral is easily missed as it continuously spins around the coral to remain hidden!

Plenty of crinoids clinging onto the gorgonian corals

Bryaninops, or sea whip gobies. There are two of them in this photo, can you find them?

Flatworms are such simple creatures but so beautiful!

Kusu Island was recently impacted by resulting oil spill following the collision between a chemical tanker and a containership “about 2.7 km, south of Jurong Island”.
