Grey bonnet snail (Phalium glaucum). There were so many of them that I simply had to ignore them in order to look at the rest of the marine life.
One of the most intriguing finds for me were several of these coils of what seem to be egg capsules. I have never seen anything like it and I have no idea who the mama is. Probably some kind of snail and probably a large one too as the capsules were quite big.
Fig snails (Ficus variegata). Many more than on our trip here in Oct 2011 and Nov 2011. These snails are quite lively and I came across many that were 'standing up' on the sand. I'm not sure what is going on, possibly they were pushing into the sand with their large foot?
Ball moon snails (Polinices didyma) and Oval moon snails (Polinices mammilla), I saw several Eggwhite moon snails (Polinices albumen) with a white shell, many Naked moon snails (Sinum sp.). The snail in the bottom right corner I don't really know what it is. I doesn't seem to be able to retract completely into its shell and seems to produce a purple dye that smells bad.
Olive snails (Family Olividae).
Conch snails (Family Strombidae).
Moon-headed sidegill slug (Euselenops luniceps). This cartoonish slug is not a nudibranch. It is adapted for living in a sandy habitat. A broad foot and flattened body for crawling over sand or burrowing underneath. A long siphon on its back which brings fresh seawater into its gills while it is buried in the sand. With the incoming seawater the animal can also sense chemical released by potential prey nearby. It has a large oral veil fringed with lots of sensory 'hairs' on the underside to detect prey. The slug can swim for some distance by flapping the sides of its body.
Ghost crab (Ocypode ceratophthalmus) buried in the sand!
Sand star (Astropecten sp.) on our previous trip here.
Keyhole sand dollar (Echinodiscus truncatus) that we see elsewhere. On the underside, there was a strange thing poking out. A tiny parasite?
Plain sea anemone, one small swimming anemones (Boloceroides mcmurrichi).
The most amazing find was of course made by Chay Hoon. She found many of these super well camouflaged slugs among seaweeds. Can you spot it?
Tendril slug (Lobiger viridis) that she found many years ago.
Tomorrow, TeamSeagrass heads to Cyrene to do our regular monitoring there.
