Published
Witness a hungry, color-changing cuttlefish take part in an oddly adorable, psychological test. Following days of training, the cuttlefish is faced with the decision to strike and devour one of two tempting prey: Will it wait for the live crayfish or immediately strike the shrimp? Its intriguing behavior is challenging our understanding of the origins of intelligence.

This groundbreaking experiment was adapted from the Stanford Marshmallow Test, originally designed for children.
