Alligators fill their bellies with small rocks as a way to stay underwater for longer periods of time, according to a recent study in the journal Integrative Organismal Biology. Ingesting stones equal to just 2.5 percent of the alligators’ body weight increased the animals’ dive time by an average of 88 percent, extending it up to 35 minutes, Science magazine reported.
Scientists have long known that alligators, crocodiles, and other crocodylians frequently consume rocks on accident while attacking live prey or on purpose as a source of minerals, to get rid of parasites, or to help digest difficult meals — a behavior also practiced by some birds. But the new study is the first time the conduct has been shown in lab experiments to affect the animals’ swimming.
