Alligators and crocodiles seem a little less intimidating now that new research reveals they enjoy an occasional fruit during meals.
While usually known as being top predators, a new study published in the July issue of the Journal of Zoology confirms that alligators do not live on meat alone. Neither do Nile crocodiles.
A study led by the Wildlife Conservation Society says that the American alligator and a dozen other crocodile species occasionally eat fruit along with their normal meat-heavy diets of mammals, birds, and fish.
The study gives new insight into the possible role that crocodilians, some of which have large territories, may play in forest regeneration through digesting and passing seeds from fruits. Similar to the way birds eat seeds and disperse them over long distances after ingestion, or endozoochory, alligators and crocodiles may too be a vector for plant growth as their scat would contain seeds, which may eventually root themselves and grow into a new plant.
The authors looked at 18 species of crocodilian ranging from the American alligator to the fearsome Nile crocodile and found 13 of the species consumed some form of fruit including a variety of berries, legumes, nuts, and grains.
Previous studies have shown that herbivory in these reptiles has been recorded quite a few times, however the general feeling is that such acts were accidental. New observations however are confirming that these species may in fact enjoy these fruits and may provide an alternative to stalking prey.
Whether these predators should be considered strict carnivores or not, the moral of the story is: a little fruit can go a long way — especially when it comes to transporting seeds.
