Notes

This brilliant Blue Sea Slug is beautifully adapted for life floating upside down in the sea and is often found with the beautiful blue jellyfish Porpita. Blue Sea Slugs feed almost exclusively on the tentacles of Bluebottles, Physalia species. Interestingly, the nematocysts (stinging cells) on these tentacles pass through the Blue Sea Slug intact. The slug can then use these stinging cells in its own defence.
