Almost exactly a year ago I posted a message from Bernard Picton reporting Halgerda carlsoni from Tanzania, the first record from the western Indian Ocean. Your animal seems identical to Bernard's. They differ from western Pacific specimens in having black lines on the gills and rhinophores rather than spots, but in your photo the lines on the rhinophores seem to be aggregated spots so perhaps the difference is more apparent than real. It is an interesting find.
Best wishes,
Bill Rudman
