A Chromodoris hintuanensis nudibranch, a type of sea slug, traverses the dark sands just offshore in Tulamben, Bali, Indonesia.

Here is one of my favorite nudibranch pictures from my trip to Indonesia last autumn. Before I started scuba diving I had no idea that slugs (of all things) could be the wellspring of so much beauty.

Nudibranch species are so numerous that English-language common names are eschewed to prevent confusion. Thus, for sea slugs Latin names (or binomial names) are relied upon exclusively. The species shown here is Chromodoris hintuanensis, which for me is both a challenge to remember, and to pronounce!
