Cuttlefish Couple

Date January 28, 2014


A pair of reef cuttlefish in the shallow and murky waters of Singapore’s Kusu Island. These animals were in a coloration and posture that is less commonly observed. I wonder what they might have been up to. They were also really really huge. The biggest I’ve seen around here. Read the rest of this entry »

Gotta Love Muck Diving

Date January 25, 2014


Last weekend at Pulau Hantu, the visibility was absolutely terrible! It was daunting for first timers, and a little stressful for the guides because we always hope for the best conditions for our first timers! Regulars however, remained super enthusiastic and still saw a lot of critters during their dive! Diving at Pulau Hantu is a lot about attitude! If you’ve got the right one, you’re surely to be nicely rewarded. Above: Goniopora coral Read the rest of this entry »

Hantu Blog was invited to join NParks for a survey dive at Big Sisters Island this week! We’re always thrilled to check out the other islands especially since we are so focused on diving at Pulau Hantu! It’s good to see what else is out there for us to find, and to learn what’s special about each of the other islands! Diving with marine biologists from NParks also allows us to learn more about their work and witness how real science is making a difference for Singapore’s very precious coral reefs!

Diving at Pulau Hantu is all about going slow and staring hard at the substrate. A prefect critter for pleasure on our reefs then, is the sea slug. To photograph the Ceratosoma nudibranch above, I didn’t even have to dive! Just popped my head under the water, and there it was, crawling about the sargassum algae on the reef flat!
