Local diver and nudibranch enthusiast, Toh Chay Hoon, visited the reefs of Pulau Hantu over the weekend and returned with some wonderful images of Singapore’s urban reefs. She wrote, “Visibility not as good as last week. Only about 2-3m and with some currents. Nonetheless, still two good dives at the jetty with a few nudibranch sightings!” I guess the visibility has been quite good of late since 2-3m is considered low vis! It used to mean a good day!

So many nudibranchs, where to find them? What can we learn about these spineless creatures while we are observing them in the wild? One of the easiest things we can observe while out on the reef photographing these sometimes splendidly colourful seaslugs is the stuff that they eat. It also works the other way around! If you’re looking for a particular type of seaslug, it might be useful to find out what they eat, then look for them in parts of the reef where you are likely to find their food.

Yesterday I had the wonderful privilege of bringing the Ong family out for their virgin dive in Singapore waters! They chose a weekday because they wanted the reef to themselves! Ok, they didn’t say it in those words, but we did have the reef to ourselves and it was nice! Ed-Linddi (left) shared that she’d heard about diving in Pulau Hantu for many years, but never got around to arranging a trip till now! And we’re glad she chose the Hantu Blog!

Thought there was nothing new to see in Singapore! You’d be blown away by the number of new records we have been making in Singapore’s tiny slither of ocean! Divers out at Hantu in late April photographed this pair of mating nudis, and it turns out they are a new record! Goniobranchus aureopurpureus, previously known as Chromodoris aureopurpurea, is a beautifully coloured dorid nudibranch. They feed on sponges and each species has a specific association with their sponge prey, so knowing what kind of sponges these nudibranches prefer can help us locate them in the future! Thanks for Toh Chay Hoon for making this exciting discovery!

Kuiters dragonet is a curious little fish commonly found in Singapore’s shallow sheltered mud-sand flats, especially among seagrasses. It is named after Rudie Hermann Kuiter, a Dutch-born Australian underwater photographer, taxonomist, and marine biologist. He’s best known for describing many new species of seahorse. The photographs in this post were taken by Hantu Blog volunteer, Jeemee Goh. Not only is Jeemee an excellent guide, vastly experienced at navigating and discovering the hidden critters in our turbid waters, but he is also an extraordinary photographer, and has inspired many divers and underwater photographers to visit our waters with his captivating images. Here’s a collection of critters he encountered with our divers on 27 April. Read the rest of this entry »
