The net is 100 metres long! We measured it! Having to use the 50m tape twice.
Spoon pincer crabs (Leptodius sp.) with spoon-shaped tips on their pincers. The one below seems to have been recently entangled in the more transparent portion of the net. We use blunt tipped scissors so we don't hurt the crabs when we carefully snip out the entangled creatures. The other crab was more seriously entangled and had already lost a pincer and some legs.
public intertidal walk conducted by the Nature Society (Singapore). We saw them starting off into the low shores while we were in the middle of our work. There is a large drill ship and large tanker on the horizon. The area off Pulau Semakau is designated anchorage for such large vessels in Singapore for maintenance and repair.
After we finished, we walked back along the hard sandy parts at the low shore. The higher than expected tide allowed us to float our blue bags all the way back. It was much easier than having to heave them on our backs on the soft muddy high shore! In the clear waters, we also took the opportunity to check out the rest of the low shore for more abandoned nets. Fortunately, we didn't come across any.
Favid corals (Family Faviidae) and Pore corals (Porites sp.).
Galaxy coral (Galaxea sp.) among the seagrasses.
Knobbly sea stars (Protoreaster nodosus)! One was a small one, and another medium sized. The water was too murky for photos, so we gently put it on our bag for a quick shot before returning it to water.
Giant carpet anemone (Stichodactyla gigantea). Abigayle spotted the Common sea stars (Archaster typicus). In the incoming tide, we saw a Ribbon jellyfish (Chrysaora sp.) and lots of stingrays and other fishes zooming too quickly to be sure of what they were.
laid by a nudibranch!
Despite being a small all-ladies team, we had a great time removing the net! The weather was wonderfully cloudy with gentle breezes, the high water floated our bags and the company was great!
Thank you Abigayle, Rene and Kah Ming for helping with this retrieval, which is part of Project Driftnet.
