Technically, no, only crocs. According to Pierre DuCharme at The Ledger and Syd Kearney at The Houston Chronicle:
Alligators and crocodiles can be found in south Florida almost anywhere the habitat is suitable for their specific requirements ? from freshwater canals and ponds to backwater bays in estuarine systems. They can be seen basking in the sun or floating on the water with eyes and snout just above the surface, observing their world. They are survivors of an amazing group of animals and have had little need to change the successful design of their bodies in the millions of years they?ve existed.
Like mammals and unlike most other reptiles, crocodilians have a four-chambered heart. Their internal nostrils open in the back of their throat, where a special part of the tongue called the palatal valve closes off their respiratory system when they are underwater. This way they can open their mouths underwater without choking.
Alligators have a broader snout and the adults are much darker in color than their crocodile cousins. In addition, only the alligator?s upper teeth are usually seen when the jaws are closed ? in contrast to crocodiles, where upper and lower teeth can often be seen together. Hatchling alligators have alternating bands of yellow and black vertical stripes.
YES THEY CAN
