This interesting species of Dondice was discovered about 10 years ago in Puerto Rico and apparently lives exclusively on the jellyfish Cassiopeia. Cassiopeia is the jellyfish which is often found in sheltered shallow waters. It lives upside down so that the sunlight can get to its tentacles which are full of symbiotic algae. There is no indication that the aeolid retains algal cells alive in its tissues, like some other nudibranchs do, but it would be worth an investigation.
