Using a modified version of the Stanford marshmallow test, researchers at the Marine Biological Laboratory (The University of Chicago) discovered that cuttlefish had the ability to delay gratification for a better reward—and those that were able to do it for a longer duration possessed better cognitive learning abilities.

There are currently about half a trillion corals in the Pacific. Of the species studied, two-thirds of the coral species have population sizes exceeding 100 million colonies, while 20 percent of the species have population sizes that are more than a billion colonies.
“We need to know the abundance of a species to assess its risk of extinction,” said lead author Andy Dietzel from the ARC Centre of Excellence for Coral Reef Studies at James Cook University (Coral CoE at JCU).
American artist Kristin Moger, who is based in Pennsylvania, creates beautiful, precise and intricately patterned black-and-white drawings of marine life, bringing to life the animals’ dynamic and sublime personalities on paper.
