Tiny carpet anemone shrimp
Periclimenes sp.*
Family Palaemonidae
updated Jan 2020
Where seen? This tiny shrimp is often seen in Haddon's carpet anemones (Stichodactyla haddoni) on our Northern shores, including small anemones less than 10cm in diameter. One anemone may have 10 or more of these tiny shrimps! They are more active at night, when they move about on the surface of the sea anemone. They are rarely seen during the day.

Studies of some specimens found at Chek Jawa, Pulau Semakau and the Singapore Straits identified them as Periclimenes cf. obscurus. But this is suspected to be a species complex that contains more than one species and a more detailed study is required to identify them more precisely.

Features: To about 1cm. Almost completely transparent. Some with a dark stripe along the body length and blue eyes.
