            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. |

              Eggs seen through 
              the transparent body!
