Back again with Seagrass-Watch, this time to check up on Chek Jawa.
TeamSeagrass and I learn so much from Len and Rudi about our seagrasses.
The Smooth ribbon seagrass (Cymodocea rotundata) are doing very well and cover a large area. Len is having a closer look at them.
Spoon seagrass (Halophila ovalis), Needle seagrass (Halodule sp.), Fern seagrass (Halophila spinulosa)
Asian Geographic article about Chek Jawa written by N. Sivasothi with photos by Alan Yeo done before reclamation was deferred. Wow, I didn't know that this article would have such outreach and eventually result in the wonder seagrass monitoring programme that Seagrass-Watch helped to start.
Beccari's seagrass (Halophila beccarii) can still be
found in small patches near the boardwalk. This small seagrass emerges
in a rosette of about 5 narrow leaflets. While Spoon seagrasses emerge
in a pair of leaflets. This is the easiest way to tell apart these
bryozoans growing on seagrass blades for the upcoming Bryozoan and Hydroid Workshop. So I had a hermit crab's view of visitors on the shore.
Haddon's carpet anemones (Stichodactyla haddoni) on the shore.
cerianthids aka peacock anemones although they are not true sea anemones.
Garlic bread sea cucumbers (Holothuria scabra) on the shore today. Len is very impressed with this because elsewhere in the region, these sea cucumbers are over harvested and it is rare to see such large ones unmolested in a seagrass meadow.
Flower crabs (Portunus pelagicus) encrusted with living barnacles.
Common whelk (Nassarius livescens) with a pair of hitchhiking sea anemones.
Plain sand stars (Astropecten sp.), several Warty pink sea cucumbers (Cercodemas anceps), a Smooth sea cucumber, a dying Ball sea cucumbers (Phyllophorus sp.) above ground and many Striped hermit crabs (Clibanarius infraspinatus). I didn't see any Thorny sea cucumbers (Colochirus quadrangularis).

toxic to dugongs and to humans, and if they bloom too much may smother seagrasses. Len explains that Lyngbya grows quickly when there is lots of iron in the water as well as nutrients.
dugong feeding trails, we come across an abandoned driftnet at Chek Jawa. Here's more on the Project Driftnet blog
about how we removed the net and released a small crab trapped in it,
and recent encounters with driftnets and netting on Chek Jawa.
90-year old durian tree fell on it last year. Last we heard, there was an effort to rebuild the house. The rebuilding seems to be going on slowly.
Nick Baker's awesome fact sheet and photos of this snake on his Ecology Asia website.
Southern Expedition of the Mega Marine Survey
to direct surveys of our seagrasses so we can find out what animals are
