Cats on Pulau Hantu (Part 2)

Date August 22, 2017

The Hantu Blog, together with the SPCA, Cat Welfare Society (CWS) and Singapore Land Authority (SLA) successfully trapped and removed four cats that were abandoned on Pulau Hantu. This is the second time we have responded to a public alert about stray cats on the island. The first such attempt to trap and remove cats from the island was in January 2016. It is necessary for the cats to be removed for their own welfare, and that of the wild animals and environment that they are in. Read the rest of this entry »

The Darker Side of Pulau Hantu

Date August 17, 2017


By Ann Tan: A lot of people say, that there is no difference between day and night dives at Pulau Hantu (because low daytime visibility makes day dives seem like night dives!), but I think otherwise. Pulau Hantu has its own unique critters of the night. I became obsessed with night dives at Pulau Hantu about 6 -7 years ago after seeing some critters I’d never seen during the day. Since then, I have seized every opportunity for a night dive at Pulau Hantu.

Tonight’s dive site was a little bit special. I had been to this site only during the day but never at night. I’d expected to see more active head-shield slugs (Cephalaspidae) and “Shaun the Sheep” (Costasiella sp.) as I had seen these during the day. Most of all, I was hoping to encounter critters that were even more rare, and unseen during the day.

On my first dive, I made a beeline for a green blade of algae where I’d last seen “Shaun”. The first leaf I found, there Usagi (i.e. Costasiella usagi) was. Read the rest of this entry »

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.
