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 flatworms known as Pseudobiceros, and I was wondering what the difference was. Bi- suggests, there are two, and indeed all the flatworms have two antennae, so what sets them apart? Read the rest of this entry »
After a week of stormy weather, the sky finally cleared up for our Labour Day dive! Despite it not having rained the night before, the limited 2-3 meter visibility we had today was some indication of the effect of April storms on our reef. Yet reef life appeared unfazed. We entered the water as the tide was picking up and a slight current coming through. This brought some crinoids out and corals had their polyp tentacles extended out. Read the rest of this entry »

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 marine biodiversity survey. What’s interesting about this 3-year effort to document Singapore’s coastal and marine ecosystems – through dredge, dive and intertidal surveys – is that it caters for members of the public, with little or no experience, to take part in the activities.

This 10th Anniversary commemorative tee features a Tigertail seahorse (Hippocampus comes), a species of seahorse that finds shelter in the reefs of Pulau Hantu. Seahorses are threatened throughout their range by habitat loss, and collection for the trade in traditional medicines. It truly is a unique feat for seahorses to live in a reef located so close to Singapore’s urban industrial developments. The Tigertail seahorse is a symbol of how it is possible to manage healthy natural eco-systems within an urban environment, if we choose to be aware, proactive, and determined.
As the boat pulled up alongside the reefs of Pulau Hantu, and we gazed down through the water at the corals below, I reminded the divers that surface visibility can be very deceiving as conditions can be quite different once we descend below. Perhaps it was the evening showers we had on Saturday night that stirred up conditions at the islands, but we were determined to make good of this because after all, this is what local waters are famous for – low visibility! And make good we did! We made great, actually! With all creatures great and small to satisfy even the mega fauna addicts within our group! Read the rest of this entry »
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.  It is easily recognised by its yellow upper lip and black bands covering its blue base colour. Read the rest of this entry »
