BOCA RATON, FL (BocaNewsNow.com) (Copyright © 2026 MetroDesk Media, LLC) — A small, crocodile-like reptile from Central and South America has been quietly expanding its grip on the Florida Everglades for decades — and a new University of Florida study says scientists still don’t fully understand what that means for one of the country’s most ecologically sensitive regions.
Researchers at UF’s Institute of Food and Agricultural Sciences in Fort Lauderdale have compiled the first comprehensive review of the spectacled caiman, synthesizing more than 70 years of data on the invasive species. The caiman was introduced into South Florida through the exotic pet trade, with established populations documented since the 1980s. What researchers didn’t initially realize is that the animals came from multiple genetic sources — originally Colombia, but more recent samples point to Brazil and the Guayana region as well. That mixed genetic background, scientists say, may be making the species tougher to control.

The bigger concern now, according to a report shared with BocaNewsNow.com, is what happens next. Researchers say they don’t yet know whether the massive, multibillion-dollar Comprehensive Everglades Restoration Plan — the largest wetland restoration project in U.S. history — will create more or less suitable habitat for caimans. They also know little about where the reptiles nest, how far they travel, or whether restored waterways could speed up their spread into protected natural areas. “We think caimans in Florida may move more than populations in their native range because of dry-down conditions in the Everglades,” said lead author Sergio Balaguera-Reina. “This could potentially mean that they can disperse faster than we expect.”
To get ahead of the problem, researchers are satellite-tagging female caimans to find nesting areas and developing environmental DNA tools to detect new populations before they take hold. The public can also help. Anyone who spots a spectacled caiman is urged to report it through the IVEGOT1 app, by calling 1-888-IVEGOT1 (483-4681), or through the EDDMaps website.
