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.

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!

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 [...]

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.

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?
