Black-Margined Glossodoris Nudibranch
The runner up from last years Miss Underwater Sydney beauty competition was a Black-Margined Glossodoris Nudibranch with her classic frilly looks.
In fact a seaslug has won the competition for the last 4 years running - there aren't many other creatures that can compete with them in the looks department. However, there is a lot of debate over whether they should even be allowed to enter. All seaslugs are simultaneous hermaphrodites - they're both male and female.
