All That Wrapper

Date December 27, 2016

Wrappers are pretty – that’s the idea. They are intended to attract, mesmerise, and evoke a sense of allure. But once we are done with them, we crush them up and toss them aside. In spite of its evocative potential, a pretty piece of wrapper, is alas, benign. But not these. These are wrappers of […]

Celebrating 12 Years of Outreach with 12 Nudis (and a crab)

Date April 6, 2015

It’s that time of the year again when SCUBA divers in Singapore get to spend an entire day out at sea, uncovering Singapore’s magical marine mysteries! We do this once a year (that is, overdose on diving at Pulau Hantu) to celebrate the efforts of our dedicated and passionate volunteers, who have been reaching out […]

Fang Blenny's Glass House

Date January 21, 2014

Variable fang blennies Petroscirtes variabilis are small elongated fishes that can be encountered in coral reefs of Singapore’s Southern Islands. Apart from discarded glass bottles, they have also been found making their homes within the shells of large snails. Watch this video as the blenny leaves its bottle, makes an about-turn, and swims back into […]

Cryptic Critters on Whips, Crinoids, and in the Dirt

Date June 7, 2013

Not only are we on an expedition, we’re on an expedition in really turbid waters. Losing your buddy is a given. But you won’t be able to do any work at all if you lose your equipment. So the less things you have to focus on getting a grip on, the better. In an attempt […]

A Macro Look at Macro Life

Date June 6, 2013

If you love taking a closer look at life on the reef, you’ll love diving in Singapore. Though we do get surprised by some mega fauna every now and then – we’ve had schools of batfish, barracuda, and Silver moonies – to authentically enjoy Pulau Hantu’s reefs, we have to marvel at the impressive diversity […]

Pinna, Porifera, and Pseudobiceros' Penises

Date May 13, 2013

I’ve always thought these Blue-lined flatworms (Pseudoceros sp.) get their Latin name Pseudo- “not genuine” and Ceros- “horn” because they do not have “true horns”, that is, feelers. Those pinches at the top of their bodies that serve as sensory organs similar to antennae. Then I started getting confused because there is another genus of […]

Clownfish Catfight

What happens when a pair of female anemonefish meet?

Hantu Diver Gone Dredging

Date April 17, 2013

  In a departure from our monthly visits to Pulau Hantu’s reefs, Hantu Blog volunteer, Verona Huang, had the opportunity to help the folks from the Tropical Marine Science Institute (“TMSI”) in a dredge survey around the waters of Kusu Island and St John’s Island as part of the Mega Marine Survey, Singapore’s first comprehensive […]

Yellow-lipped sea krait hunting in sargassum meadow

Date March 28, 2013

A Yellow-lipped sea krait scans the reef flats of Singapore’s Pulau Hantu for an opportune meal. The colubrine sea krait, banded sea krait or yellow–lipped sea krait (Laticauda colubrina) is a species of sea snake found in tropical Indo-Pacific oceanic waters. [1] It is easily recognised by its yellow upper lip and black bands covering […]

Cuttlefish Talk

Date December 2, 2012

A pair of cuttlefish were spotted along the reefs of Singapore’s Pulau Hantu. They were about the same size. Could they be siblings? Or were they individuals from different clutches that find safety by being in a pair?
