Are Great Whites in the Gulf of Mexico?

Great white sharks inhabit the waters of the Gulf of Mexico. While not commonly associated with this region, scientific evidence and numerous sightings confirm their presence. The Gulf serves as a significant, seasonal habitat for these apex predators.

Documented Presence

The presence of great white sharks in the Gulf of Mexico is well-documented, with records dating back decades. NOAA officials reported catching great white sharks off Sarasota, Florida, in 1937 and 1943. From 1979 to 1982, the National Marine Fisheries Service documented 35 great whites as bycatch in the Japanese longline fishery off Florida.

More recent evidence comes from scientific tagging, commercial fishing bycatch, and confirmed visual sightings. In February 2025, a video of a great white shark was filmed off Tampa, Florida, and in April 2025, a 14-foot great white was filmed nine miles off Destin, Florida. Tagging efforts by organizations like OCEARCH and the Atlantic White Shark Conservancy have confirmed their presence, with numerous tagged individuals like “Katharine,” “Betsy,” “Unama’ki,” and “LeeBeth” appearing in Gulf waters. These tracked sharks have been observed across the Gulf, including off the coasts of Florida, Louisiana, Alabama, and as far west as Matamoros, Mexico, near South Padre Island, Texas.

Reasons for Their Presence

Great white sharks enter the Gulf of Mexico primarily due to their migratory patterns, the availability of suitable prey, and favorable water conditions. The Gulf often serves as a wintering ground or migratory pathway for some populations, especially those from the North Atlantic. These movements are linked to seasonal changes in water temperature, as great whites prefer waters approximately 50 to 80 degrees Fahrenheit.

While the Gulf may not have large seal populations, it offers an abundance of other suitable prey. The rich marine ecosystem supports a variety of large fish and marine mammals, including tuna and various types of rays. The depth and temperature gradients within the Gulf provide diverse habitats where these sharks find ample food sources.

Research and Tracking Efforts

Research and tracking efforts have helped understand the movements and behavior of great white sharks in the Gulf of Mexico. Organizations like OCEARCH and the Atlantic White Shark Conservancy use satellite tagging programs to monitor these sharks. These tags transmit signals when a shark surfaces, allowing researchers to track their journeys in near real-time.

Notable tagged sharks, such as “LeeBeth,” have revealed extensive travel, with LeeBeth traveling over 2,000 miles from South Carolina into the western Gulf of Mexico, further than any previously tracked white shark. Other tracked individuals, including “Contender,” a 14-foot, 1,600-pound male tagged off the Florida/Georgia coast, also frequent Gulf waters, particularly during winter months. This ongoing data collection helps scientists map migration routes, identify important habitats, and understand population dynamics, contributing to conservation efforts.

Coexisting with Great Whites

The presence of great white sharks in the Gulf of Mexico carries a low risk of encounters for the general public, as these sharks typically remain in deeper, offshore waters. They are not commonly found near popular swimming beaches. Despite their size and predatory nature, great white sharks generally avoid human interaction.

For those who recreate in deeper offshore waters, general safety guidelines can help minimize potential interactions. Avoiding swimming at dawn or dusk, refraining from wearing shiny jewelry, and steering clear of areas with known baitfish concentrations are prudent measures. Great white sharks play an important ecological role as apex predators, helping maintain the health and balance of marine ecosystems. Understanding their presence and behavior fosters responsible coexistence and supports conservation efforts.
