300-tonne oil spill in the East Johor Strait in Jan 2017. So it was a relief to see such a magnificent array of marine life there this morning.
It was so wonderful to see a lot of sponges of various kinds all along the survey route from the House No. 1 Jetty to the Chek Jawa Front Beacon! I first noticed improved sponge diversity during our survey in Jul 2016, which improved further during our Jun 2017 survey.

Ball flowery soft corals, and one big one with a White soft coral snapping shrimp in it. As for sea anemones, there were many Haddon's carpet anemones, lots of Swimming anemones. On the rubble, many Posy anemones.
Candelabra sea fans and Gnarled sea fans, plus a few that I can't identify.
Boulder pore corals. All were unbleached and had no dead patches. Some were brown, others dark blue or green.
Flowery disk corals, from small ones to medium sized ones.
Zebra coral here and there, even on an abandoned glass bottle.
Boulder sandpaper coral, and one colony of a hard coral which I can't quite identify.
Knobbly sea stars on the outer edge. With a few smaller ones on the seagrass areas
Biscuit sea stars, with small ones on the seagrass areas and big ones on the rubbly area. But today I saw several really huge Cake sea stars with bold patterns. I also saw one small Eight armed sea star.
Oval heart urchin near the seagrass meadows, many large brittle stars and a sprinkling of a variety of sea cucumber. I've always wondered why sea cucumbers are so abundant on Changi but less so on Chek Jawa.
flatworms of all kinds.
Brown spotted moray eel. When the tide turned, it wriggled away very much alive. Rene also spotted a pair of Estuarine seahorses! Some 'missing' animals were Onyx cowries (I saw only one) and the octopuses I saw were tiny.
Jun 217, seagrasses are doing well with Smooth ribbon seagrass now growing thickly west of the floating pontoon. The seagrasses were lush. Growing thickly and leaf blades green and clear of growths (epiphytes). There were lots of nice green Needle seagrass (skinny leaf blades), Fern seagrass, Spoon seagrass (big and small leaf blades). Smooth ribbon seagrasses have taken over most of the seagrass meadows near the coral rubble area.
Tape seagrass growing on the outer edge of the rubbly area. Most were near the Beacon. Only one had longish leaf blades, the rest had cropped leaf blades.
dugong feeding trails! Today we did not come across any nets or traps along our survey route. Hurray!
Chek Jawa and Pulau Sekudu may be affected by the 2030 landuse plan by the Ministry of National Development. The plan includes plans for a road link (black line) from the mainland jumping off at Punggol, crossing to Pulau Ubin through Chek Jawa to jump off to Pulau Tekong before circling back to the mainland on Changi East. Proposed reclamation (in yellow) will bury Pasir Ris shores, Pulau Sekudu and Chek Jawa as well as a large amount of shore at Changi Beach.
