Dwarf Cuttlefish and Egg Cluster (image) California Academy of Sciences Caption They may look like a cluster of purple grapes, but these inky balls are actually eggs from a dwarf cuttlefish, Sepia bandensis. As the eggs continue to develop, they become translucent, at which point the babies can be seen swimming inside their egg casings. To date, more than 350 dwarf cuttlefish have hatched at the California Academy of Sciences, most of which have been sent to other aquariums and research institutions. The academy is the first institution in the country to successfully breed these animals.
