Protecting wild places doesn’t mean excluding people. Users can be stewards of land and sea. Stand-up paddle boarders found a hawksbill turtle off East Coast today and didn’t hesitate to rescue the endangered reptile that was tangled in discarded fishing nets. Photos: YP Loke

Soup of Egg and Sperm

Date May 12, 2021

Bad luck can run out. Hantu Blog volunteer Nicholas Chew didn’t give up on his quest to witness the mass spawning of corals in Singapore during a night dive. His tenacity finally paid off with an opportunity to participate in one of Earth’s spectacles of Nature!

Birth of a Coral Reef

Mass coral spawning is a rare natural spectacle that few have the privilege to witness. Hantu Blog volunteer, Min Hui Khoo, has been hard on the heels of this year’s mass coral spawning event.

Waiting for a Coral Spawning

Date April 10, 2021

There are a few special times of the year, when the phases of the moon and tides align to trigger a global marine underwater phenomenon called mass coral spawning. I witnessed my first mass coral spawning in 2003. It was also at Pulau Satumu, also known as Raffles Lighthouse. We camped on the island in […]

New to Science, Found in Singapore

Date January 23, 2021

By Nicholas Chew: I had seen some photos of an extremely cryptic nudibranch Phestilla viei by Chay Hoon over the last few months. It had superb camouflage, unlike anything I’d seen before.

Above: A cool cuttlefish remains still even as our diver Chay […]

Sea Snails, Ostracods, and the Oldest Penis on Earth

Date November 2, 2019

You’ve probably never heard of an ostracod. Why would you? It’s a tiny creature, about the size of a mustard seed, and nothing much more than a head. It is not exactly the thing that many divers go looking for when they are out on the reef. While ostracods are not popular, they truly are […]

Traits of Shapes

Date October 14, 2019

In a recent blog post, I spoke to Hantu Blog volunteer Gina Tan about some lesser-known insights related to the shapes of coral. Samuel Chan is a PhD candidate at the National University of Singapore’s Reef Ecology Lab. After reading our post about coral shapes, he reached out to us to clarify some of the […]

Shapes of Coral

Date October 7, 2019

I recently had the fantastic opportunity to catch up with Hantu Blog volunteer, Gina Tan. We spoke about sinking corals, butterflyfish and coral spawning. I was absolutely fascinated by her insight and unique views of the life history of reefs and wanted to learn her opinion about how our reefs, and in particular, Singapore reefs, […]
