The researchers hatched cuttlefish eggs and waited until the animals were a month old. Then they started testing the young cephalopods.

A partition jutted out from the center of the box toward the cuttlefish. As it swam toward the apparatus, the cuttlefish would have to make a choice between one chamber and the other.
