Dolphin Bubbles Eats Regurgitated Prey in a Rare Foraging Trick
A male bottlenose dolphin nicknamed Bubbles at Lady Elliot Island regurgitates prey by causing bigeye trevally to vomit under stress, then eats the regurgitated food. Documented in Ecology and Evolution, this kleptoparasitic foraging appears to be a learned, energy-saving strategy that may involve echolocation cues to identify targets, though more data are needed to determine how common the behavior is among dolphins.
