I was advised it was a Blue spotted Sea Hare, however, I have not been able to find any information on this. I thought, at first, it was a Stylocheilus striatus but it does not appear to have the lateral lines. Can anyone identify this? Photographer: Doug Clark.

Comment on Bursatella leachii by Doug Clark. I seen or heard of around today around the South Mole of Fremantle. In the same location I also saw Chromodoris collingwoodi [page Plate ], also not recorded here before Not sure if there is anyone who would like to come for a trip to have a look?
On the same dive I saw some other slugs the book says are rare, the dive was just over 2 hours in m of water. Length: mm. Photographer: Brent Murdoch. Please drop me a line if anyone wants any photos or is interested in a dive a short drive close to Fremantle Regards Brent Murdoch brent murdoch.
Best wishes, Bill Rudman Rudman, W. Photographed it on the beach in Florida. Photographer: Mark Javer. Thank you, Mark brightsidestudio gmail. This is the sea hare Bursatella leachii. Comment on Bursatella leachii from Florida by Mark Javer. What it eats, if it dies, is it toxic to my fish.
Thanks, Ontario, Canada. I suspect your animal is Bursatella leachii. This animal normally lives on an organic layer found growng over the sandy bottom, so it will probably find things to eat in your aquarium - even help to keep the glass clean. Will it be toxic to your fish if it dies? Sea hares have acid glands in their skin so I doubt if the fish will try nibbling it while it is alive.
If it dies, then like all rotting material it will foul the water, but no more than a dead fish or a soft coral would. Comment on Bursatella in aquarium by Lori Blair. They looked like slow-moving, hairy sea slugs? The attached picture shows 2 of them close together, photographed through about 1 foot of water at low tide. Length: inches. Photographer: Angie.

It will also be interesting to see how much the DNA sequence varies for the various geographical types of species that are cosmopolitan such as Bursatella leachii as their polymorphic forms are diverse.
Anyway, we have aquaculture ponds for shrimp and one just got colonized by thousands of Bursatella leachii. Strangely the postlarval shrimps have disappeared died? Also, if there is any commercial use of these animals, I may decide to preserve this pond as a closed system breeding population of this invasive species. Is it true that Chinese actually eat this animal? Locality: Umas Umas River area, 0. Photographer: Ms. Claire Emmanuelle Bue.

Also with such limited funds availble for basic research I would rather encourage students to study the basic biology of some of these common, abundant animals than to study slight differences in their cytochrome oxidase genes. We could then be able to answer questions like yours.
I assume this is partly because they feed on the blue-green algal layer [cyanobacteria] often found growing over the substrate. Concerning the use of Bursatella as food or medicine in China.
I can find no good evidence of any sea hare being used as food, but there are places [Fiji, Philippines] where their eggs are eaten. I have no information on whether they are used for traditional medicine. Many other marine animals have been called sea slugs [see sea cucumbers ] so the literature is quite confusing. Have a look at the Fact Sheet on the topic. There is no real evidence to suggest it is toxic in normal concentrations.
Comment on Bursatella leachii in Malaysian shrimp ponds by Huan Ung. First off, I wanted to thank you for a wonderful site. It has provided me with endless amounts of fun poking about and learning about sea slugs. On a walk along the beaches of Honeymoon Island, Florida, I found about 40 slugs crawling along the bottom of a shallow pool of water.
The tide was out, and the pool appears to be a typical depression found along the shoreline here, no more than 8 inches in depth, with a sandy bottom and surrounded by grasses and similar vegetation. The slugs were roughly 4 inches in length. Though you cannot see it clearly in the photos, the edges of the "frills" on the slug were a vibrant, almost glowing light blue-green.
I have never to my recollection seen this slug in the waters in this area, though I have seen other slugs in the past. Length: 4 inches. Photographer: Sonnia Smith. Again, thank you for the site, and thank you for the opportunity to send you a hello from Florida! Sonnia Smith sonnia. Yes this is B. In a recent message [ ] about subspecies of B.
Head short and broad, with many branched median villi. Oral tentacles broad and projecting laterally. Foot broad, with a short acute tail. Parapodia short, not very mobile, their edges recurved and fused posteriorly high up, bearing a row of simple villi. A large arcuate ctenidium usually protudes through the dorsal slit.
