She suspects its existence stems from three reasons: The area has enough food that the mantas can grow, it doesn’t have too many predators, and it maintains a warm temperature that’s optimal for development.Ĭurrently, Pate is working to gather more data. “Right off the coast from the condos, among millions of people, we have this rare nursery,” Pate says. ![]() But the most exciting thing she’s turned up is the developmental ground for baby giant mantas in an area off Fort Lauderdale and Miami. She studies giant manta rays in Florida to figure out how many there are, where they spend their time, what they eat, and how fast they mature, among many other questions. “They’re these big, charismatic creatures that remain overlooked by science,” Pate says. They’re the biggest rays in existence and are found across the world’s oceans, from Indonesia to the Yucatan peninsula to the east coast of the United States (though Pate and other scientists suspect that the giant manta rays in Florida might be a distinct species). Manta rays have the largest brain of any fish, and they’re social and can form long-term bonds with one another. They’re filter feeders, drawing in plankton, and have to continuously swim to keep water moving over their gills so they can breathe. They lack the venomous barb on the tail that makes stingrays dangerous. She leads the Florida project on giant manta rays, which are a mysterious, little studied, and often misunderstood species. Since female giant manta rays only produce a single, large pup every few years, and the juveniles may spend two or three years growing in these waters, it’s a vital area to protect.īased near West Palm Beach, Pate works for Marine Megafauna Foundation, a global organization that studies large marine animals, with a focus on whale sharks and manta rays. And after six years of gathering data, Pate has discovered that South Florida is home to a rare nursery of 125 juveniles. They have personalities.” The huge marine fish-its wingspan can reach more than twenty feet across-is endangered worldwide. “From that moment, I was hooked,” she says. Although they are protected in international waters and by laws of certain countries, they travels often through unregulated waters and are still being fished all over the world.The first time marine biologist Jessica Pate swam with a giant manta ray in 2016, it flipped upside down and swam along underneath her, studying her as much as she was studying it. Overfishing has the real potential to wipe out large numbers of giant oceanic mantas due to the fact that they live so long and reproduce so little. Their size make them particularly susceptible to entanglement in fishing nets even when they are not voluntarily fished out. Their gills is still in high demand mostly by the traditional chinese medecine market. The Manta Trust and Marine Megafauna foundations are both working globally to research and protect the mobulae family and their habitats. The International Union for Conservation of Nature (IUCN) declared manta rays as ’vulnerable’ in 2011. All of this combined make their reproduction quite slow! The mother will usually have two years elapse between pregnancies. Manta-mums usually carry only one pup, but 2 pups have already been recorded. They are born independent after a 12-13 months gestation period. ![]() Manta rays can live as long as 50 years and are ovoviviparous, which means that they start development in an egg and hatch within the mother's body.
