The tide is so high it nearly touches the base of the Main Bridge! But this makes it much easier to see and photograph the fishes! Finally, a better look at the Striped nose halfbeak (Zenarchopterus buffonis) and now I understand its common name! It does have a stripe on its nose! Which is hard to see when the fish is far away.
|Among floating leaves and twigs, |
this surface-dwelling fish is sometimes overlooked.
Mullets (Family Mugilidae)? I also saw from a distance, some Garfish or Needlefish (Family Belonidae), but they didn't come close enough for a photograph.
|The little fishes were swimming in circles.|
When we headed for the mangroves, the water was still high but rapidly falling. We managed to successfully check up on the various plants there. One of the trees here that I've not noticed properly are the large tall old Teruntum trees. I remember Dr John Yong sharing that Teruntum is a feature of this mangrove.
This old gnarly tree with fissured bark turned out to be Teruntum putih (Lumnitzera racemosa)! I found out only after processing the photos of the canopy when I got home. Awesome to see one so tall! Those I've usually seen are short bushes.
|Once I started looking, I realised there were many of these trees.|
Mangrove St. Andrew's Cross spider (Argiope mangal) which was described by Joseph Koh, our dear friend and spider expert who wrote the Guide to Spiders of Singapore. Only the female Argiope mangal builds webs. These contain only 2 white zig-zag lines, called stabilimentum. Argiope versicolor, which is found inland, makes the "full" cross with 4 stabilimentum.
Yellow-Lined Epeus (Epeus flavobilineatus) which is reported from our mangroves and which Joseph Koh noted as a new record for Singapore. Apparently the male has this kind of 'punk hairdo' on the top of its head.
Tree climbing crab (Episesarma sp.) has red tips on its white pincers.
Face-banded crabs (Perisesarma sp.) were everywhere!
Bumblebee goby (Brachygobius kabillensis)?
Javanese ricefish (Oryzias javanicus) or Priapus fish (Neostethus sp.)?
Giant mudskippers (Periophthalmodon schlosseri).
Some sort of insect larva has been eating its way through this mangrove tree leaf throughout its caterpillar life. Possibly the appropriately named Leaf miner moth (Phyllocnistis sp.). It tunnels its way through the leaf, without breaking either the upper or lower leaf surface. When it first started, the tunnel is thin and narrow, becoming wider as it grows larger, finally ending in a folded leaf edge where it stopped eating to pupate, then breaks through the leaf to emerge as a winged adult.
Jerome noticed lots and lots of these tiny translucent spheres among the moss-like hairy green seaweed that forms carpets under the mangrove trees. The spheres are hard and can't be compressed. I'm not sure what they are. Are they artificial? Plastic beads? Oh dear.
International Coastal Cleanup Singapore works tireless to educate about marine litter. Kranji is one of the major sites for the Cleanup.
