Read the following paragraph and answer the question that follows:

Alligators are freshwater reptiles. However, people have come face to face with them in mud in a salt marsh in Georgia. Finding alligators in the salt marsh is not a mystery or a miracle. At least 23 species of predator have been spotted living in surprising habitats.

It gives us astonishing insights into the lives of animals and helps conservationists improve the old stomping grounds of these creatures.

Which of the following statements provides the most plausible explanation of the predators' behaviour?
