Our first trip for the New Year is of course back to Kranji to check out the mangroves there. It's high tide when we arrive!
How nice to come across a few Gedabu (Sonneratia ovata) which are listed as Critically Endangered. It's my first time seeing such nice tall Gedabu trees. They were fruiting! With some fallen fruits too! I had seen signs of them on my earlier visits but didn't come to this side and thus missed them. That's why I feel it's important to check up on our mangroves over several trips.
Berembang (Sonneratia caseolaris)? This kind of tree is also listed as Critically Endangered.
Teruntum (Lumnitzera sp.). I think he's right! Dr John Yong mentioned that this area is known for its large and old Teruntum trees.
Bakau mata buaya (Bruguiera hainesii). I still can't get a good shot of the flowers. Brandon managed to take a photo of a propagule on the tree! But we didn't find any fallen propagules today.
Bruguiera gymnorrhiza) may have a pink calyx, but sometimes also pale or yellow. The calyx clasps the propagule, instead of sticking out as in Bruguiera hainesii. This kind of tree is still considered rather common. But I still appreciate our common mangrove trees. Tumu can be quite pretty especially when flowering and with well formed buttress and knee roots.
Bakau putih (Bruguiera cylindrica). The pointy parts of the calyx bend all the way back away from the propagule in this kind of tree. I must say I am often frustrated by this tree when looking for the rarer Bruguiera. Because most times, the suspicious tree turns out to be Bruguiera cylindrica!
Tengar merah (Ceriops zippeliana) growing in a sunlit opening in the mangrove forest. This kind of tree is listed as Endangered and it was first discovered in Singapore in 2009 by Dr Yong and his colleagues.
Mangrove cannonball tree (Xylocarpus granatum) with many large bowling ball sized fruits hanging in the canopy. On the ground, some fallen fruits and even some seeds (they are irregularly shaped and emerge from the round fruit). Although this tree is considered common, I still think large ones are quite magnificent to encounter, with lovely patchy peeling bark and lush green leaves.
Wax plant climbers (Hoya sp.). But alas, I couldn't spot any that were flowering. Yet another reason to regularly check up on our mangroves. Many of our mangrove plants can only be identified by their flowers or fruits.
Black-mouth mangrove nerites (Dostia cornucopia). When the icky mud is removed, we can see the pretty shell pattern! The underside is black.
Lined nerites (Nerita articulata) on the tree trunks.
Red chut-chut (Cerithidea obtusa) has a red body and white mouth. The Black chut-chut (Cerithidea quadrata) has a dark body and dark mouth.
Red berry snails (Assiminea sp.) which I just can't resist photographing because they look so cute.
Heavy jumper (Hyllus diardi). I'm not too sure what the other one is.
Tree-climbing crabs (Episesarma sp.) while the lower row are Face-band crabs (Perisesarma sp.).
Ecology Asia page on skinks, I can't really figure it out. It's probably NOT the mangrove skink which does not have keeled scales, while the one I saw does have keeled scales. See also the Mangrove skink in the Guide to the Mangroves of Singapore.
Ornate leaf slug (Elysia ornata).
Elysia bangtawaensis which is found in mangroves and have been reported to be sighted elsewhere in large numbers too. I've never seen this before.
So much to discover in our mangroves!
