These were relatively common on hydroids at Tulamben. Previously we had these combined with Doto sp. b104. It is still possible that they are the same, but Doto sp. b104 tends to be larger and appears to have different egg masses. Also, the structure of the dorsal processes appears different, although that could mostly be due to size. We have included numerous photos because the variation suggests there may be more than one species figured below. These need a bit more work in order to be properly sorted out.
