So, outside of being voted most awesome looking sea slug, it turns out this particular sea slug has an important scientific function: It has been called the “missing link” between the sea slugs that feed on hydroids and those that eat corals.We should also note, this pic is perhaps a little misleading, because this little guy is less than an inch long.
