Footage shows stunning rare "blue dragon" sea slug swimming on surface
- 6 years ago
This video, filmed February 4, shows a Glaucus atlanticus – commonly known as a "blue dragon" sea slug – swimming off Bondi Beach in Sydney.
The rare organisms are shell-less mollusks that float upside down by using the surface tension of the water to stay up. Often seen washed up on beaches, "blue dragons" feed on Portuguese man o' wars, a jelly-like creature commonly found in the Atlantic, Indian and Pacific Oceans.
