Bosellia sp appears to be a very frequent inhabitant at Hastings Point due to the areas of Halimeda weed
growing from low tide level down. These animals were found in 1m at low tide, in weed patches on rock
faces protected from most swell.

This small egg coil(4mm dia) was found on a Halimeda leaf on a small plant that had several Bosellia animals
on the same "branch". It is highly likely that this is the egg coil of Bosellia sp but as I did not see it actually
being laid it cannot be confirmed.
