The strange anemone that Marcus found on Pulau Semakau a few days ago turned out to be a very rare one indeed!From Marcus' photo above, both Dr Tan Swee Hee and Dr Daphne Fautin have confirmed that this is the beautiful Heteractis crispa!
It does look very similar to the Snaky sea anemone (Macrodactyla doreensis) but has key differences. See Marcus' The Annotated Budak blog for all the details about Heteractis crispa!
