This Science Mag article features pictures from inside the manta rays womb. The entire duration of a manta ray pregnancy lasts around 13 m onths. It includes the only images on record showing the birth of a manta ray pup in its natural habitat. The baby manta stays wrapped in the burrito shape during its birth. Seconds later, you can see the wings unfurl as the manta pup twirls into life, swimming and gliding through the ocean.
Here at Manta Ray Advocates along the coast of Kona, Hawaii, we have been lucky enough to identify at least 10 — 15 manta pups over the years. When birthed, manta pups unfurl out of the wrapped-up-burrito shape into a feet wingspan. Kirk as he must have been only a few days old when he was first sighted in Pelagic mantas create larger manta babies, with a wingspan of around six feet. We have gained this insight from a video birth shot in an aquarium in Okinawa, Japan.
Interestingly, there are no shared features between father and pup. In the future, we are looking to test some DNA samples on the Kona coast of Hawaii in order to determine paternity. Some theorize that female mantas and their manta pups share similar markings. Additionally, unlike mammals, there is no lasting connection between the manta pup and the mother. The young manta rays are on their own from the beginning.

In most fish species females lay the eggs and the males fertilize them. Males have two organs called claspers attached to their anal fins. When mating they will insert one of them into the females cloaca to transfer the sperm that will fertilize the eggs. Some sharks and rays are viviparous will keep the eggs in their uterus others oviparous will lay the eggs.
After mating they will lay their eggs covered by a leathery case on the sea floor or attached to reefs. The baby will develop inside of this egg case and when the food supply yolk is finished the shark will escape through a slit in the case and swim away. Many have opportunistic remoras attached to their undersides, consuming scraps that result from feeding. Mantas have been observed swimming in slow vertical loops within rich feeding areas.
They aggregate in areas that offer large concentrations of zooplankton, with up to 50 individuals within an area. Oceanic islands and submarine ridges provide precious few sites containing nutrient-rich waters and an abundance of zooplankton, in the otherwise nutrient poor tropical regions.
Reproduction Males reach maturity at a disc width of at least 13 feet 4 meters while females mature at a disc width of Manta rays reproduce by ovoviviparity with the birth of one pup during a breeding season. Embryos have been shown to reach 50 inches in disc width and weigh 20 lbs. Parturition occurs in relatively shallow water where the young remain for a few years prior to expanding their range offshore. Predators Due to their size, the only predators of the manta ray are large sharks.
Parasites Specific parasites associated with M. However, this ray is known to visit wrasse cleaning stations on a daily basis. These fish function to remove parasites from the mantas. Manta birostris was first described by Dondorff in Discover Fishes Manta birostris. Manta Manta. Order: Myliobatiformes Family: Myliobatidae Genus: Manta Species: birostris Common Names Manta ray , Atlantic manta, Australian devilray, blanketfish, devil ray, devilfish, devil-ray, eagle ray, giant devil ray, giant manta, giant Atlantic manta, great devilfish, manta, manta ray, Pacific manta, prince alfreds ray, sea devil, and skeete are common names in English language.
Importance to Humans Underwater photographer with a manta. Danger to Humans Mantas are of minimal danger to humans. Habitat Habitat of M. Biology Dorsal A and ventral B view of a juvenile male. Image courtesy Fishes of the Western North Atlantic, Distinctive Features Adults are easily recognized by their large triangular pectoral fins and projecting cephalic fins, forward extensions of the pectoral fins that project anteriorly on either side of the head.
