As well as the sea slugs from Chek Jawa, we have also found some other animals on the intertidal flats at Changi, here in Singapore. Anything you can tell us about them would be very interesting.

This is a species of Armina but unfortunately there are a group of very similar looking species with longitudinal black lines on their mantle, and yet we know little about them. I suspect this is what I am calling Armina sp. 2 on the Forum. I have decided to follow Baba (1949) in identifying it as Armina semperi (Bergh, 1861). The blue foot with the orange-yellow border seems quite distinctive.
Species of Armina usually eat Sea Pens, but its seems a few will eat other related soft corals.
