9/25/2023 0 Comments Giant manta ray reproductionMother Manta rays typically give birth to between one and two pups at a time but are not needed to stick around to parent their pups as the pups instinctively know how to feed. This gives Manta ray pups the best chance of survival in the ocean and ensures that when they are born they are already grown and can be independent. So, do Manta rays lay eggs? No, they are ovoviviparous which means instead of laying eggs they give birth to live young after carrying the fertilized egg for around one year. However, their slow reproduction process and outside threats mean that the Giant Manta ray is currently endangered. Manta rays have a long lifespan and can live up to 40 years old. This gives them the best chances of survival and since they have very few natural predators they don’t need parental care as much as other species. These impressive animals are filter feeders that swim with their mouths open to feed on zooplankton, krill, and other small fish.īaby Manta rays are born live and independent, meaning they are capable of feeding and fending for themselves from birth. When baby Manta rays are born, they have to be large enough to swim and learn how to feed right away. How Many Babies Do Manta Rays Have?Ī mother gives birth to usually one or two baby Manta rays at a time. It’s exciting to think that Manta could potentially be capable of having pups for a large part of their lives, and gives us a home for the Manta ray population in the future. However, there have been some instances where Manta rays as old as almost 50 years old have fallen pregnant, so it’s still up for debate as to when they stop being fertile. The Manta ray’s fertility age is still unknown, but it is thought to be between the age of 10 – 15 when the rays reach sexual maturity. Some male Manta rays have even been known to pursue already pregnant females, so it can become tricky to identify who the father of some Manta ray pups are, and often relies on a DNA test to definitively know for sure. The “last Manta standing” is usually the one that will inseminate the female, but it’s now known that a single male Manta can still impregnate females even after the train has ended. These trains can last for weeks on end, but as courtship starts to progress, many male Manta rays will abandon the train. Manta trains can be as large as twenty male Manta rays ranging from both young and old following one female. This is because one female Manta tends to swim at the front, whilst followed by several male Manta rays. The starting point of the Manta ray reproduction process is called the “Manta-train”. Most Manta rays typically have a life expectancy of around 40 – 50 years old, with females not reaching sexual maturity until they are between 10 – 15 years old. Much of the Manta ray reproduction process is still very much a mystery, but we do know that they have a very slow reproduction rate. Seconds after they are born, they find their bearings and their wings unfold and they spring into life ready to take on life and its many challenges. When born, the pups are rolled up tight like a burrito, with their wings wrapped around their bodies so they can be born. This gives the appearance that they are flying through the water, instead of swimming. The female hoses her eggs for around 1 year, then the mothers swim to shallow waters and give birth to their young, usually under the cover of nightfall.ĭue to Manta rays being cartilage and not bone, they are incredibly flexible. When ready, they give live birth to their young which can be as large as 1 – 2 meters long and weigh as much as 40kg. Unlike many fish species that lay eggs and are externally fertilized, Manta rays actually don’t lay eggs and are internally fertilized. 5 Final Thoughts How Do Manta Rays Give Birth?
