Threatened and Vulnerable in Singapore

Date July 24, 2017

Singapore reefs may be small but they are not insignificant! A weekend visit to the island of Pulau Hantu shows that local reefs are home to some of our planets’ most endangered and vulnerable animals!

Mating Pygmy Squids

Date May 27, 2017


How to tell baby squid from pygmy squid? Pygmy squid mate, baby squid don’t (or so we think anyway). Marine biologist Dr. Jeffrey Low was leading a reef survey dive for Hantu Blog volunteers when he had what he claims to be one of his best dives at Pulau Hantu!

One of nature’s most spectacular events

Date April 24, 2017

By Gina Tan: The sky is dark and I hear thunder in the background. I wait enthusiastically for the divers from NParks to arrive before we can head out to Pulau Satumu. Today, 17th April 2017 is going to be a very special day for me; it’s my once in a lifetime opportunity to experience coral spawning in Singapore waters! We board the boat, and I sigh a quiet relief as I watch the thunderclouds move inland; this means we can go ahead with our dives!

We Celebrate 14 Years of Bringing You Closer to Singapore Reefs

Date March 26, 2017

Screen Shot 2017-03-26 at 17.11.37
The Hantu blog celebrated its 14th anniversary last week. What better celebration than a couple dives at our beloved island! It was a beautiful sunny day, and we were blessed with a (relatively) fine 5m of visibility. Conditions were unusually calm, rendering the water surface smooth like glass. We got to the western seawall during low tide, and I decided to see what was in store for me on the deeper sandy bottom. By Nicholas Chew Read the rest of this entry »

A Backyard Dive into Resilience

Date February 27, 2017

By Galen Mandez – An hour is all it takes to wake up, wash up, have a coffee, pop my gear into the boot and make my way down to the marina where our dive boat awaits. It’s a diving Sunday and a strange relief for someone much more accustomed to an eight-hour journey to Tioman.

It’s my first familiarisation dive with the Hantu Blog Divers and the weather is perfect as seven eager
divers pull out from the Marina and make the 30-minute journey to Hantu. Read the rest of this entry »

Tambja Tambja everywhere!

Date February 20, 2017

There was a Tambja explosion at Pulau Hantu this weekend. Not literally. But there were lots of them! They offered a nice spot of colour to the reef, and we never get bored of looking at them! Some were squished up like the one above… Read the rest of this entry »

Intertidal Walk at Big Sisters Island

Date February 16, 2017

By Nicholas Chew – On Sunday, a few Hantu Blog volunteers were invited to participate in an intertidal guided walk at Big Sisters Island, part of our very own marine park. The walk was organised by Ria Tan, creator of and an avid environmental activist. Over the years, Ria and other like-minded nature lovers have been regularly documenting biodiversity on our shores with a mission to promote the appreciation and conservation of our natural heritage. It was a great privilege to join them! Above: The jetty at Big Sisters Island. Read the rest of this entry »

Signs of an oil spill

Date February 14, 2017

The Hantu Blog focuses its efforts in Singapore’s southern islands, but our living shores extend far beyond that. I decided to join Ria Tan at Changi Creek in Singapore’s northeast, for a look at the impact of a 300-tonne oil spill that occurred in the East Johor Strait last month. Signs of the oil spill were not obvious to me, but once Ria pointed them out and shared how to recognise indicators of an environmental impact, I began to see the signs everywhere.

Hidden Treasure

Date February 13, 2017

It can be hard to get a grip on what stands out in Singapore. Buildings change. Landscapes change. Places from our childhood disappear. Where can we go where we can set foot on sand that was not moved by humans? Cyrene Reef is one of those places. I was fortunate to visit this reef thanks to a trip organised by Ria Tan who is one of the many people who have been sharing and monitoring this reef for over a decade. Read the rest of this entry »

Monitoring our reefs (Pt 2)

Date February 8, 2017

Over several weekends (and some weekday nights!) we had Dr Jeffrey Low introduce us to the art (and science) of reef surveys! Through his enthusiastic sharing, we learnt some of the survey methods commonly used to monitor coral reefs. He also taught us the importance of citizen science and its vital contribution to conservation work. We also learned to identify some common lifeforms found on our local reefs, and how to record our findings in a way that is useful for scientists and agencies to use.
