Long before NASA’s Kennedy Space Center became the home for launching humanity’s future, the waters surrounding the Florida spaceport housed one of Earth’s top apex predators. It’s not unusual for people who regularly boat, fish, or swim in nearby lagoons and beaches to spot Sharks living their best lives alongside the rockets sending astronauts into space.
The bull shark is the most common shark species in the Indian River Lagoon. The Vehicle Assembly Building turn basin is a hotspot for young bull sharks on Kennedy property.
Even though popular culture often portrays sharks as a threat to humans, the actual danger is very limited. In fact, sharks play an important role in the ecosystem. Their food hunting helps regulate prey populations, benefitting marine diversity and habitats such as coral reefs and seagrass.
Throughout the month of July, cable channels air a wide range of “Shark Week” programming to delight their viewers. In honor of this heightened interest in our fine finned friends, here are some fun facts about these fascinating fish who make their homes in the waters of the Space Coast.
Eighteen different shark types have been documented near Kennedy. Among them are: Atlantic sharpnose, blacknose, blacktip, bonnethead, bull, dusky, finetooth, great white, hammerhead (great, scalloped and smooth), lemon, nurse, sandbar, sand tiger, spinner, thresher, and tiger. The most common in the lagoons near Kennedy is the juvenile bull. Researchers have spotted more bull sharks recently than ever in the area, primarily because the Space Coast serves as a popular spot for females to give birth and as a nursery habitat for their young.
Marine biologists working for NASA regularly monitor the waters in and around Kennedy. Besides ensuring that NASA stays compliant with endangered species and marine fishery regulations, these biologists help the agency minimize the impact of the U.S. space program on local wildlife and habitat. They’re also vital to one of Kennedy’s main goals: creating a culture of conservation. Their work helps NASA’s partners at the Merritt Island National Wildlife Refuge and Canaveral National Seashore properly manage the local marine population, ensuring the survival of sharks and endangered species such as sea turtles.
Acoustic telemetry and unmanned gliders help track the sharks in and around Kennedy. Kennedy researchers routinely tag sharks with individually unique sound transmitters and set them free. As each shark moves, biologists collect data on their movements from underwater receivers, giving insights on how they live and where they go. The researchers use similar techniques to study other marine life on center and nearby. Powered by the sun and waves, unmanned ocean gliders extend the range of surveyed areas, transmitting data back via satellite. The gliders can be piloted remotely by computer and have customized equipment that can be altered based on the mission.
The most common types of sharks found off of Kennedy’s beaches are Atlantic sharpnose, blacknose, blacktip, finetooth, and lemon. That’s according to a recently published research paper from Kennedy’s marine biologists. The five-year study of shark populations near offshore sand shoals – funded by NASA and the United States Bureau of Ocean Energy Management – also showed that sharks in the area are highly mobile and prone to seasonal migration. That includes the juvenile lemon, which is also known for hanging out in Brevard’s surf in large numbers during the winter. Although it is on the rise in the southeastern United States, the shark population is in decline in many other parts of the world.
Sharks on Earth are doing poorly for a variety of reasons, including being fished in numbers that are unsustainable for their survival. Proper understanding and management near Kennedy are helping increase the numbers of most shark species in the area, benefiting marine life and the ecosystem as a whole.
