What is "grania"

Grania is a genus of marine annelid worms in the class Clitellata. They are found at many depths in sands throughout the world. They are generally about in length and mostly colorless or white, though Grania colorata, a recently discovered species found in the Great Barrier Reef, is green.

The gens Grania was a plebeian family at Rome. Although none of them ever obtained the consulship, the family was of "senatorial rank", and was well-known from the latter half of the second century BC. In Imperial times, a number of them became distinguished in military and provincial service.
