This difference in salt tolerances could also explain differences in their global distribution. Therefore, alligators stick to freshwater habitats, such as lakes and marshes. Although alligators have the same salt gland, that gland is not very effective and limits the alligator's tolerance for salt water. This ability allows them to live in salty marine environments, such as Australia's saltwater crocodiles ( Crocodylus porosus) - which reside throughout mangroves, swamps and deltas. Crocodiles have lingual salt glands - on their tongues - which allow them to expel excess salt from their bodies, according to a study published in the Journal of Comparative Physiology. One major difference between alligators and crocodiles is where they live. ISOs can be found solely on the head and around the mouth of alligators crocodiles have ISOs on almost every scale on their body, according to the Journal of Experimental Biology. Despite this, alligator bites are on a slight uptick. When people witness an alligator snapping its jaws and growling, they assume its preparing to attack. Alligators would prefer to avoid interactions with people altogether. These sensory organs allow the predators to detect pressure changes in the water caused by potential prey. Even though these alligators are a threat to humans, theyre still wary of us. Growling, glowing alligators will captivate you for a total of 42 seconds. There are some exceptions to the rule, such as the mugger crocodile (Crocodylus palustris), which has a rounded snout reminiscent of an alligator, according to San Diego Zoo Wildlife Alliance.īoth of these reptiles have tiny black specks called integumentary sense organs (ISOs) on their heads. If you need a dose of alligator to improve your day, this is THE video to watch.
Alligators have a U-spaced rounded snout that is wide and short, whereas crocodiles have a longer pointed, V-shaped snout. The shape of their heads is also a key identifier. The teeth on the bottom row of a crocodile's jaw, on the other hand, sit on the outside of the mouth and slot into grooves along the top jaw, according to Biology and Evolution of Crocodylians. Alligators have an overbite, and so the teeth on the bottom jaw fit into sockets in the top jawline and are concealed. There is one quick-fire way to distinguish a crocodile from an alligator: Look at their jawline. Do alligators and crocodiles look different?Īt first glance, crocodiles and alligators look quite similar however on closer inspection, the two have very different snouts.
