Residents near Lake Poinsett are concerned about the presence of Argentine black and white tegus, an invasive lizard species that can grow up to five feet long and threaten native wildlife. Homeowner Brady Deluca described encountering the large lizards, which have been seen swimming and even entering crab traps in the neighborhood. The Florida Fish and Wildlife Conservation Commission warns that these tegus prey on the eggs of native species, including alligators and sea turtles, raising fears for local wildlife. Authorities urge the public to report sightings but not to approach the animals themselves.
