![]() ![]() The manta ray’s mouth is made up of gill rakers and gill arches, with the latter working to keep the cavity open for feeding - manta rays close their mouths when they are not feeding. If a fish inadvertently enters a manta’s mouth, the manta will quickly spit it out. Mantas can’t eat you, however, as they don’t have the ability to swallow anything other than plankton. The mouth of the manta ray looks like a big cavernous cave, which can be intimidating: It’s so large and looks like it could just swallow you right up! ![]() In Hawaiian waters, it would be a tiger shark. Incidentally, the manta rays have very few natural predators, but the two they do have are some of the ocean’s most dangerous: large sharks and killer whales. If threatened, they simply swim away fast. What mantas do have is a rather small “tooth band” - hardly a reason to fear them, as manta rays are known to be “gentle giants.”įor protection against predators, mantas depend on their huge size and fast agile swimming rather than their tooth band inside their mouth. Unlike their relatives the stingrays, manta rays don’t have a stinger, barb or teeth. They use the dorsal fin to maneuver their bodies, as they’re incredibly acrobatic in their movements. The manta’s mouth is in the front part of their body, and we’ll get into more detail regarding their mouths in the next section.įrom the ocean’s surface, if you see a dorsal fin sticking out and think it’s a shark, it could very well be a manta ray as they often swim in shallow water. We go out to swim with manta rays (almost) every day, and so far we’ve identified two tailless mantas that didn’t appear to have any problems without it. Viewing from the topside of a manta ray, you’ll find pectoral fins, cephalic horns, eyes and a tail.Įven though manta rays have tails, they can actually exist without one. Reef mantas measure a bit smaller, growing about 14 feet across (about 5 meters). ![]() That makes them the largest of the more than 500 species of rays and skates. Giant oceanic mantas can measure up to 22 feet (7 meters) from wingtip to wingtip and weigh up to 3,000 pounds (1,400 kilos). Manta rays are clearly recognized by their enormous size. There are two types of manta rays: the migratory giant manta ray (also called oceanic or pelagic manta) and the reef manta ray, which lives in shallow coastal areas. Their brain size is estimated to be as big as an adult fist, and they are fairly more advanced at problem-solving and communicating than your average fish. That’s why they’re called “cartilaginous fish.”Īmong fish, mantas have the largest brain-to-body ratio. They’re all part of a family called “elasmobranchs” and have skeletons made of cartilage instead of bone. Manta rays share many characteristics with their ocean relatives like skates, other rays and sharks. The word “manta” means “blanket” or “cloak” in Spanish, and it’s quite accurately descriptive for these large, flat, diamond-shaped cold-blooded fish with eyes on the sides of their heads. Here’s another good article on Manta Rays by Martina Wing for Manta Ray Advocates. ![]()
