They’re trying to get a date. Pairs of male dolphins will develop elaborate underwater routines to impress females. Bottlenose dolphins that engage in synchronized swimming with their peers tend to see the glass as being half full.
Some of these dolphins frequently swim in tight-knit groups, and they’re the ones who appear the most optimistic, according to a study of eight captive animals.
In the experiment, individual dolphins were trained to swim towards one of two targets. They were taught that when they reach the left one, they receive applause and eye contact, while the one on the right delivers herring – the jackpot – and dolphins swim faster towards it.
