The alligator is a huge reptile with a length of more than 3 meters and a weight of several hundred kilograms that feels great both in water and on land. This is one of the most bloodthirsty predators that feeds exclusively on animal food, capable of almost instantly killing not only a large animal, but also a person. Alligators and crocodiles look very similar to each other, with so much that an ignorant person is unlikely to be able to distinguish them.

Перевод:

Аллигатор — огромное пресмыкающееся длиной более 3х метров и весом в несколько сотен килограммов прекрасно чувствующее себя как в воде, так и на суше. Это один из самых кровожадных хищников питающийся исключительно животной пищей почти мгновенно убить не только крупное животное, но и человека. Аллигаторы и крокодилы внешне очень похожи друг на друга, при чем на столько, что не сведущий человек вряд ли сможет их отличить.
