Yea the sepia bone packaging has turtles on it.

Also I just read an interesting fact that answered my question, it appears sepia is the family that cuttlefish comes from.
Quote from wikipedia.
"Sepia is a genus of cuttlefish encompassing some of the best known and most common species. The name of the genus is the Latinized form of the Greek σηπία, sēpía, cuttlefish."
