Coral Rebirth on Satumu reef

Date April 23, 2018

Early this month, Hantu-blog contributor Chay Hoon was fortunate enough to witness and capture a rare event within the Singapore marine ecosystem – mass coral spawning. This mass reproductive event occurs once a year and is difficult to precisely predict. Marine biologists in Singapore have been observing local reefs for over a decade to narrow down the event to the span of a few days. Thanks to years of tenaciously pursuing their curiosity, we get to get a glimpse of this amazing event through Chay Hoon’s photos.

Nudibranchs – What on earth are they?

Date March 14, 2018

By Aidan Mock: As a diver, I have long wondered what exactly nudibranchs are. They are one of the more commonly sighted creatures on the Hantu reefs and come in an amazing array of colours, shapes, and sizes, but I’ve never really see them doing anything. I decided to spend some time investigating these creatures and share about them here. (Below: Dermatobranchus sp. spotted in Hantu on January 2018. Photo credit: Toh Chay Hoon)

Swimmer Crabs

Date February 12, 2018

Red swimming crabs are a common sighting on many of Singapore’s shores, especially near reefs and coral rubble. They are especially active at night, are extremely fast in the water, and can be quite fierce! Don’t attempt to handle them! They give a good pinch! Read the rest of this entry »

Malaysia’s Largest Seagrass Bed

Date January 1, 2018

By Lim Lay Beng: The Johor Strait is widely known for its major shipping lines and the largest business port in Malaysia. Less known to public are the diverse marine habitats and the wonderful marine biodiversity in the surrounding waters. I made a day trip to Mukim Tanjung Kupang in Johor to discover this beautiful landscape with the passionate volunteers of Kelab Alami and Cicada Tree Eco-Place! Read the rest of this entry »

Singapore’s under-rated reefs

Date November 5, 2017

By Debby Ng: I don’t get to dive Singapore waters as often as I used to since I returned to university to work on a degree (one more year left!). However, I’ve not had to lose touch with our reefs because of the troves of photographers that enthusiastically visit our reefs every weekend. I rely on their images to continue to discover our reefs, and they have really taken me on a journey. Each time I receive photographs from divers, I sit at my desktop, big smile on my face, eyes wide open, thrilled to share their discoveries. Sometimes, in the quiet of my room, I let out a big “WoOoW!” almost teary eyed, completely blown away by their discoveries. (Above: Doto greenamyeri, 2017 © Gina Tan)  Read the rest of this entry »
