Cuttlefish (Sepia officinalis) belong to an order of cephalopods called Sepioidea. They appear suddenly in the fossil record as cephalopods. "Ancestral cephalopods" are unknown. Using hydropropulsion as their primary locomotion, cuttlefish are quite mobile and extremely agile.

Every year scientists discover new and amazing animal designs, and 2015 was no exception. Each find brings a new reminder of the same message every generation needs to hear: “The heavens are Yours, the earth also is Yours; The world and all its fullness, You have founded them. The north and the south, You have created them.”¹
