![]() Two of their more notable features are the cephalic fins on either side of their head, which are used to funnel plankton-rich water into their mouths while feeding. Manta and mobula rays share a fairly similar body structure. Manta rays were only split into two species in 2009, and there’s probably a third species residing in the Atlantic.Ģ. We know that there are 11 species in the ray family, counting both manta rays and mobula rays (now among the world’s most threatened fish). 10 things you never knew about manta raysġ. Giant mantas are listed as Vulnerable A2abd+3bd+4abd on the IUCN Red List of Threatened Species :Ī taxon is Vulnerable when the best available evidence indicates that it meets any of the criteria A to E for Vulnerable ( see Section V ), and it is therefore considered to be facing a high risk of extinction in the wild. ![]() There is minimal danger unless attacked (especially harpooned) or otherwise startled, but the enormous size and power of this ray should invite respect. On Yap, the young mantas are sometimes seen in the waters surrounding the mangrove system where they take shelter during their infancy. ![]() The actual birth of a manta is something rarely seen by humans and it has only been captured on film once. They become active as soon as they have rolled out their wings. A few months later, 1-2 manta pups are born rolled up like tubes. The actual mating is done belly-to-belly. Young mantas grow very rapidly.ĭuring the mating season (December to late April in Yap), mantas gather in large numbers and several males can bee seen courting single females. Females give birth to a 1-2 pups that measure about 1.2 m wide and weigh roughly 45 kg. Yolk nourishes the pups instead of placenta. Giant mantas reproduces via aplacental viviparity, also called ovoviviparity, where the young hatch from eggs inside the female’s body. They can, however, pack a very powerful punch with their wings. According to Yapese myth, mantas can wrap their wings around humans to squeeze them to death, but this is untrue. Mantas do not have venomous spines on the tail. They are no threat to larger ocean animals unless threatened their only defense is their size and large powerful wings. Like other filter feeders, manta rays have reduced, nonfunctional teeth. Some small crustaceans and fish may complement the diet. They use the unfurled cephalic (head) fins on the head (which look like horns when they are not feeding) to funnel plankton-rich water into the mouth where gill rakers filter out the plankton. Giant manta rays are primarily plankton feeders. They are known to migrate around the world in search of plankton-rich waters. Giant mantas are found in temperate and tropical waters near continents and islands of all oceans. Mantas are dark brown to black on the dorsal side with pale margins they are mostly white on the ventral side. These graceful swimmers swim by moving their wing-like pectoral fins, which can grow up to 9 m wide, but average about 6.7 m. Recent studies of genetic samples, however, show that Manta hamiltoni is the same species as Manta birostris and Manta alfredi is its own species. Manta alfredi – Prince Alfred’s manta ray.It was previously thought that three species of giant manta existed: To confuse things even further, two of the Mobula species, Mobula mobular and Mobula hypostoma, are also commonly referred to as the devil fish and lesser devil ray, respectively. There is also a Mobula genus that are smaller bottom-dwelling rays. The Manta genus is what is commonly thought of as manta rays. Remoras ( Echeneida sp.) are frequently seen with mantas near their mouths and even inside their gill cavities, hanging out to feed on parasites on the manta’s body and lost bits of the manta’s food. They are very acrobatic and are able to leap high from the water. ![]() These harmless, majestic creatures have short tails and no stinging spines. Giant mantas, Manta birostris (Walbaum, 1792), aka Atlantic mantas, devil rays, mantas and Pacific manta rays, are the largest of the rays and are closely related to sharks. Oceanic mantas are common fish subsisting in the area of thoondu. As we were not aware of the behavior of most of the creatures in the sea, we ran for safety although it is the most tranquil and shy fish swimming in the sea. An oceanic manta, looking dark and mysterious, ascended like a “stealth bomber.” The creature was swimming peacefully. Everyone stumbled in the water and ran towards the beach. It was huge, measuring around 20 feet in length. Without warning we saw a “black area” on the surface of the water, near the edge of the seacoast. Hundreds of people gathered on the beach for maahibun, celebration to mark the beginning of the Ramadan. It was a joyous day in thoondu, the northern beach of Fuvahmulah.
