Lobiger viridis has been found in clumps of a couple of different kinds of Caulerpa algae, C. urvilleana and C. racemosa, on lagoon reefs at Kwajalein and Enewetak Atolls, usually at depths of about 7-20m. It is a difficult animal to spot in its normal habitat. We also have what we are calling Lobiger viridis in Hawaii, although there is a chance that is a different species.
The closeup below shows the rolled tube rhinophores.
The animals are often found stretched along the Caulerpa runners with their appendages flattened into a line, making specimens quite difficult to spot.
