My, what big teeth you have: alligator sightings throughout the U.S.

Alligators are a threatening species to many.

A number of the reptiles have been captured on film recently, strolling within site of humans and striking fear into some.

Large male alligators are territorial and will defend prime territory from intruders.

Though a sighting may feel rare, there are an estimated 5 million alligators spread throughout seven southeastern U.S. states, according to Defenders of Wildlife, a national conservation organization.
