"Eat one marshmallow now—or wait a few minutes and get two? This famous behavioral test is supposed to distinguish between impulsive children and those more likely to think through their actions—and thus, do better in academic life. Now, scientists have given a similar test to cuttlefish, The New York Times reports. Replacing the marshmallow with a shrimp, researchers gave the mollusks the option to eat two shrimp now—or eat one shrimp with the promise of an extra reward. Most of the cuttlefish chose the latter, researchers report in Royal Society Open Science. The find suggests that—like people—these mollusks can delay gratification if they think it will pay off in the long run."
