Those sea-going crocodiles usually have something else on their mind when they pass by surfers and swimmers on the Pacific beaches.
Genetic analyses show that there is substantial breeding between colonies of crocs that inhabit the river mouths. And once in awhile, a large river croc is seen in the sea headed to another river mouth.
Things could be worse. And they are getting that way in Florida.
The University of Florida reports that DNA tests there show the invasion of Nile crocodiles in the wild. There have been some captures of the creatures.
These are the African crocs (Crocodylus niloticus) that easily reach 18 feet and are known to eat zebras, small hippos and humans, said the university, adding that the creatures can weigh as much as a car.
“Now three juveniles of the monster crocodile, have been found in South Florida, swimming in the Everglades and relaxing on a house porch in Miami,” the university reported Friday.
Scientists have expressed their concern and suggested that the African crocs travel from their homes as part of the worldwide pet trade. Florida’s Everglades also is plagued by Burmese pythons, which also is an invasive species and responsible for feasting on a number of other species in the wilds.
