my last trip here in August and in May.
The shy little guy is a Pebble crab (Family Leucosiidae)! It does indeed look like a pebble and it can rapidly burrow into the sand, leaving only its tiny eyes peeping out. We also saw lots of little Flower crabs (Portunus pelagicus) with some moults of larger ones, many Spotted moon crabs (Ashtoret lunaris) and one colourful Flower moon crab (Matuta planipes). Rick also spotted an Elbow crab (Family Parthenopidae).
Baler snails (Melo melo) I did see only medium sized shell occupied by a Striped hermit crab (Clibanarius infraspinatus). There were many of these hermit crabs on the shore.
Flat slipper snail (Crepidula walshi) on the inside of the shell, and Conical slipper snail (Calyptraea extinctorium) on the lip of the shell. The smaller slipper snails are males stuck on top of the bigger females!
Tongue sole (Family Cynoglossidae).
Volvotella slug (Volvatella vigourouxi), the only slug of the day. Other colourful creatures in the seagrasses include many Pink warty sea cucumber (Cercodemas anceps) and the Thorny sea cucumber (Colochirus quadrangularis). There were also many empty shells of Window pane clams (Placuna sp.), a dead Hammer oysters (Malleus sp.). Also a few large White sea urchins (Salmacis sp.).
Cake sand dollars (Arachnoides placenta), Plain sand stars (Astropecten sp.), Painted sand stars (Astropecten sp.), a few Sea pencils, a Ball sea cucumber (Phyllophorus sp.), Smooth sea cucumbers and two Notable sea cucumbers (Holothuria notabilis).
dugong feeding trail!
Needle seagrass (Halodule sp.), Spoon seagrasses (Halophila ovalis) and Fern seagrasses (Halophila spinulosa). They were healthy and lush, with fresh clean blades. Although there were patches with exposed rhizomes and bases of leaf blades, I didn't come across any bleaching blades.
Scalpel feathery seaweeds (Caulerpa scalpelliformis). Easy to mistake for seagrasses, these are green seaweeds.
Solitary tubeworm (Diopatra sp.)out of its tube, a rare sight! The beautiful iridescent worm has tentacles on its head and feathery stuff on the side of the body.
Tomorrow, we will be making our annual trip to the mysterious and special Lost Coast at Changi East.
