In 2008, researchers discovered that there are actually two distinct species: the reef manta ray, which tends to live along coastlines in the Indo-Pacific, and the giant oceanic manta ray, which lives in all the world’s major oceans, spending most of its life far from land. Manta rays have two horn-shaped fins protruding from the front of their heads, which has also given them the nickname “devil fish.”įor decades, scientists thought there was just one species of manta ray. “Manta” means blanket or cloak in Spanish, describing the look of the animals’ large, flat, diamond-shaped bodies, which are characterized by triangular pectoral fins. The sea creatures live in tropical, subtropical, and temperate ocean waters across the globe.

There are several activity companies in Kona who offer highly rated guest feedback. Some divers mention that these giant fish swim around them in a slow and graceful shape, and wonder whether they are observing or being observed. Unlike stingrays, manta rays don’t have a stinger, so divers have nothing to fear.Īmong the ocean’s other species of cartilaginous fish such as sharks, manta rays show to be a little more tolerant to human presence. Like many other mammoth fish in the sea, they are filter feeders that eat the smallest of prey. Are Giant Manta Rays Safe To Swim With? YES! No two bellies are alike, allowing researchers to track manta rays and identify them from year to year. The spots and blotches on the underbellies of giant manta rays are equivalent to human fingerprints. Research is limited so the numbers aren’t universally accepted but these are the best scientific estimates at present. Giant mantas have an estimated life expectancy of 40 years, and it is believed that some can live as long as 50. The rays also blew bubbles in front of the mirror, behavior that Ari had not observed in the rays before Hawaiian Mantas Live A Long Life The fish changed their behavior in a way that suggested that they recognized the reflections as themselves as opposed to another manta ray. Only a small number of animals, like great apes and bottlenose dolphins, have passed the mirror test.Ĭsilla Ari, of the University of South Florida in Tampa, filmed two giant manta rays in a tank, with and without a mirror inside. Giant manta rays have been filmed checking out their reflections in a way that suggests they are self-aware. Rays are one of the only fish species on earth to demonstrate self-awareness via a mirror test. And the size of their brains apparently translates to high intelligence. Newborn manta rays have wingspans of approximately six feet! How is that possible? Because they come out of the mother’s birth canal resembling “rolled burritos.” Giant Manta Rays of Hawaii Are Incredible Smartĭolphins are known for their intelligence, so it might surprise you to learn that manta rays have the largest brains of any fish. Giant manta rays have wingspans that can reach as large as 25 feet and the largest can weigh as much as 3,000 pounds! A common size is a wingspan of approximately 15-feet.
