Dolphins feed and rest less when boats are nearby

Close approaches by boats impede the feeding and resting habits of Indo-Pacifc bottlenose dolphins.

The dolphins are frequent targets of Australia’s dolphin watching industry, which brings boats in close proximity to the dolphins.

When boats came within 50 meters, dolphins were also observed to stay closer to one another.
