Reef glider

The reef glider is a massive, omnivorous nudibranch from the Shallow Seas in 100 million AD, in The Future is Wild.

The large form of a reef glider can often be seen sweeping through the water, silhouetted against the bright surface and throwing its shadow across a red alga reef. From its bulbous, teardrop-shaped body protrude three pairs of paddles. A long bunch of streamer-like filaments trails behind. It is difficult to believe that this is a variety of nudibranch, bigger than any of its relatives. During previous times, they were unflatteringly called sea slugs but, despite their ugly common name, they have been dainty-looking creatures, colorful and elegant, their gills forming fernlike arrays on their backs.
