Cuttlefish are far more intelligent than we give them credit for. In fact, a recent study conducted by Dr. Alex Schnell from the University of Cambridge, found that cuttlefish passed an adaptation of the ‘Marshmallow test’, designed in the 1970s to test children’s self-control.
This study is an important piece in the evolutionary puzzle because cuttlefish (and cephalopod) brains are so different from vertebrate brains, and yet appear to support similar cognitive features, such as self-control.
