Ever heard about the expression "Crocodile tears"? In our culture, it means showing insincere remorse and comes from the fact that crocodiles produce tears when they eat their prey. However, it doesn't mean they actually cry. UF zoologist Kent Vliet carried out a study and found the tears in crocodiles may occur as a result of the reptiles hissing and huffing, a behavior that often accompanies feeding. Air forced through the sinuses may mix with tears in the crocodiles' lacrimal, or tear, glands emptying into the eye. The glands produce a fluid that helps to clean the eye and lubricate the passage of the nictitating membrane across the eye's surface. |

Crocodiles can hold their breath underwater for at least one hour without coming up for a breath of air as they can reduce their heart rate to 2-3 beats per minute. Researchers found that the reptiles can adjust their oxygen consumption, enabling them to dive for longer. The longest recorded time a crocodile held its breath is eight hours in cold water, as they use less energy and oxygen compared to when they are in warm water. |

In most parts of the world, it is illegal to hunt crocodiles for their skin. Under the Endangered Species Act, it is illegal to bring into the United States many products made from the skin of alligators, crocodiles or related reptiles called caimans. Items made from the American alligator can be brought into the country as long as they are for personal, non commercial use. The skins of most crocodile species are prohibited. |
