Everyone loves a good bit of worm news. Even if they think they don't, they do.
Researcher Pierre De Wit, at the Department of Zoology of the University of Gothenburg, has been analysing the species belonging to the genus Grania, part of the annelid worm class Clitellata. These worms can be found in marine sand habitats ranging from tidal zones to the deep ocean. They are typically around two centimeters in length and white in color.
Much of this research has been in Australia's Great Barrier Reef. De Wit and his colleagues have found four new species of Grania worm - one a beautiful green-colored worm named Grania colorata. The research team has also described a species of Grania worm in Scandinavia (Grania occulta), only distinguishable by DNA. Surprisingly enough the DNA evidence points to an entirely separate evolutionary history, linking the worm to a species that looks completely different.
Yet another story about how looks don't matter, only DNA.
