![]() “They’re smart, almost like the dolphins of fish,” says Setyawan. Some are ready and willing to show off their bellies and identify themselves, while others swim in the other direction. Some are shy and some are more extroverted. His team can tell them apart from the unique spot patterns on their bellies. Manta rays’ large brain-to-body ratio allows them to have individual personalities, says Setyawan. His findings were published in May 2022 in Frontiers in Marine Science. “It took eight years of research to prove we had found it,” he says. ![]() In this protected environment, the babies are birthed and live until large enough to survive elsewhere. Setyawan says he and his colleagues have found the world’s first confirmed manta ray nursery in Raja Ampat. Scientists think that the animals give birth in manta ray nurseries, where most of the mantas living there are pups. Manta moms give birth to around one live pup every two to three years, and then she sets them on their way.

In the morning or afternoon, for example, they regularly find their spot on the coral reef and enjoy what basically amounts to a marine spa treatment.Īs the tiny fish and crustaceans clean the rays, Setyawan bears witness to a sea creature in its element. ![]() Much of his observations occur in what are called “cleaning stations.” Manta rays often hover over coral reefs while cleaner fish, like the wrasse fish and the scarlet cleaner shrimp, remove parasites, dead skin cells and bacteria from the rays’ skin.Īlthough manta rays tend to fly solo, they’re known to gather at such cleaning sites during certain times of the day. It’s a slow-growing, long-lived species that has been shown in some cases to live up to 60 years, says Setyawan. The giant manta ray is the largest ray in the ocean, with a wingspan of up to 30 feet. Their natural predators are killer whales and large sharks.Underwater view of Giant oceanic manta ray in tropical Nusa Penida island, Indonesia (Credit: Denis Moskvinov/Shutterstock).They are nicknamed “Devil Rays” for their “horns” which are actually extensions of the fins that help to funnel plankton (their main prey) into their mouths.Because of their enormous size, their only known predators are large sharks and humans. They have a large brain relative to their body size in comparison to other sharks and rays.Unlike other rays, mantas do not have a spine on their tail for defense. “Manta” is Spanish for “cloak” which refers to their large blanket-shaped bodies.The average wingspan of a Giant Manta Ray is 22 feet and they can weigh as much as 3,000 pounds. ![]() Little is known about their life history or ecology but researchers believe they may live 30-50 years. Pelagic manta giant manta ray oceanic manta ray they usually roam the. Even though reef mantas are huge already Their habitat and distribution we’re still learning about their migration patterns, but there are very clear differences between both types of manta rays. Manta rays are found around the globe in temperate and tropical waters. Their size the giant manta ray is bigger than the reef manta. Both manta rays are filter-feeders, actively combing the waters for the smallest of prey, and using their cephalic fins to channel water into their mouths. Size at maturity for the Giant Manta Ray may vary slightly throughout its range, but males in southern Mozambique mature at approximately 400 cm DW while. There are 2 types of manta rays, the Giant Manta, most commonly shown in media, and the Reef Manta. The manta, unlike other rays, does not have a spine on its tail for defense. The wingspan of a manta can reach 20 or more feet across and they weigh as much as 3,000 pounds. The manta ray is striking in its appearance with its black and white coloration and enormous size. ![]()
