No, pink manta rays do not lay eggs; rather, they are ovoviviparous, meaning they give birth to live young. During mating season, male manta rays transfer sperm to the female using specialized organs called claspers, and the female carries the embryos internally until they are ready to hatch.
Gestation usually takes around a year before the female gives birth to two to six pups at once. Pink manta ray pups are highly precocial, meaning they are self-sufficient and can swim immediately after birth.
How rare is Pink Manta Ray?
Rare and stunning, the Pink Manta Ray is considered an elusive species due to its lack of forming large groups or schools and difficulty of tracking.
Satellite tagging has revealed that their population is wider than originally anticipated, and have been seen across the western and central Indian Ocean, the coast of East Africa, Australia, and around Madagascar.
Currently, no exact estimates on their population size have been calculated, thus it is difficult to effectively initiate conservation strategies. By gathering more data and raising awareness, however, we may be able to help protect and increase the number of these remarkable animals.
What is the scientific name of Manta Ray?
The scientific name of Manta Ray is Manta birostris. Manta Rays are large rays belonging to the family Mobulidae, in the suborder Myliobatoidei.
Do all Rays lay eggs?
No, not all Rays lay eggs. Rays are a diverse group of cartilaginous fish, with over 600 known species and many have adapted to their environments differently.
Some species lay eggs that have hard shells and some do not lay eggs at all but give birth to live young. The different methods of reproduction vary between species and so not all Rays lay eggs.
Why Stingrays do not lay eggs?
Stingrays do not lay eggs like most other fish. This is due to the unique anatomy and biology of the ray. Unlike other fish, the reproductive organs of stingrays are located within the body and not externally, thus rendering external egg-laying impractical.
Furthermore, due to the semi-internal reproductive organs of stingrays, a sperm transfer must occur directly from the male ray to the female ray in order to conceive offspring.
Thus, in comparison to other fish, stingrays do not have the luxury of leaving eggs to be fertilized independently of any direct contact. This difference in the biology of stingrays also explains why most of them reproduce in much smaller numbers than most other fish.
Why are Pink Manta rays pink?
For years, scientists have been speculating about the vivid pink coloration of manta rays. One theory is that it serves as camouflage, making it harder for predators to spot them.
Another hypothesis links the color to the ray’s diet of zooplankton, which contain red carotenoid pigments that may be absorbed. Some also suggest it may be a form of social or sexual signalling , but the exact reason remains a mystery.

Manta Rays – A Comprehensive Overview
Manta rays are majestic and curious creatures that are the source of both wonder and awe. While the elusive nature of manta rays is difficult to get close to, understanding the species can provide valuable insight and appreciation into their beauty.
This article will take an in-depth look into manta rays, examining species, diet, breeding, and more.
Manta Ray Species
Manta rays are marine animals belonging to the elasmobranch family (a group of cartilaginous fish that includes sharks and skates).
There are two species of manta ray – the reef manta ray (Manta alfredi) and the giant oceanic manta ray (Manta birostris). Both species of manta ray inhabit the coastal and open-ocean regions of tropical and subtropical waters worldwide.
Manta Ray Diet
Manta rays are mainly filter feeders, and have the largest brain to body mass ratio of any known fish. They have a distinctive way of capturing their food, which is usually tiny plankton, small crustaceans, fish, and krill.
By scooping their large cephalic fins towards the source of their food, they form a “net” with which to trap the plankton. They also rely on scavenging, and occasionally preying on small schooling fish.
Manta Ray Breeding
Manta rays can reach sexual maturity at a fairly young age – 6 years for reef manta rays, and 8 to 10 years for giant oceanic manta rays. While their mating behavior is still unknown, courtship and mating can occur both during the day and night.
Manta rays reproduce through ovoviviparity, which means the embryos are nourished in the egg until they hatch and the pup is born in an advanced stage of development. Female manta rays can produce 2 to 4 young every 2 to 3 years.
Manta Ray Nests
While manta rays don’t make traditional nests like many other marine species, they have been known to congregate at cleaning stations and coral reefs, likely to seek relief from parasites, lice, and skin lesions. This congregating behavior could explain why female manta rays can reproduce only once every 2 to 3 years.
What colors are Manta Rays?
Manta Rays come in various shades and colorations. Generally they are gray to black on top and white on the underside, with a unique pattern of black or white spots along the head, dorsal fins, and upper body.
Additionally, the black color of their body is often dappled with areas of brown, gold, yellow, or even pale blue or white. Pink Manta who cruises the waters around Lady Elliot Island, is the only known pink manta ray in the world. With the variation in color and markings, no two Manta Rays are exactly the same.
How do Manta rays breed?
Manta rays are known to be ovoviviparous, which means they give birth to live young after eggs have been fertilized inside the female’s body.
Mating occurs most frequently during the months of May and October, in locations known as “aggregation sites” near coastal regions, including in the Caribbean and Mediterranean Sea.
To increase their chance of success in mating, males will engage in competition to determine who will get to breed with the female, sometimes involving swimming side-by-side with each other to try and catch the female’s attention.
A female may also have a “harem” of male suitors waiting to breed with her. After successful mating, the gestation period typically lasts six to twelve months before the female gives birth to one or two offspring.
How long is Manta Ray pregnant?
Manta Rays have a unique pregnancy among fish, lasting an average of 13 months, one of the longest among fish species. They usually give birth to a single pup but on rare occasions, twins are possible. The gestation period can vary from 10 to 16 months.
Manta Rays take 1 to 2 years to reach sexual maturity. Upon birth, manta ray pups are prepared to venture into the open ocean after their extended gestation period.
How do Manta rays give birth?
Manta rays give birth in an interesting manner; the female ray typically remains still, floating in the water as her pup slowly moves through her cloaca until it is born.
The newborn will immediately start swimming around, independently from its mother, since mantas do not take care of their offspring after birth.
The gestation period for Manta rays typically lasts about 12-13 months, and usually one pup is born at a time. To aid in giving birth, Manta rays may sometimes swim close to the surface of the water, with their wingtips barely touching, as the baby is expelled.
What do Pink Manta rays eat?
Pink Manta rays are apex predators of the ocean, consuming mostly zooplankton and small fish. To feed, the rays move their lower jaws from side to side in a motion similar to sieving, trapping plankton and small fish within their gaping mouth.
They can filter up to 6000 liters of water per hour in order to consume their food. They also prey upon squid, crustaceans, and sometimes other Manta rays. Due to their wide and large mouth, they can feed on very large prey when they find it.
Where do Pink Manta rays live?
Pink Manta Rays, also known as Mobula Munkiana, inhabit tropical and sub-tropical waters around the world. They are found in all the world’s major ocean basins, from the eastern Atlantic to the Red Sea, from the Gulf of Mexico to the Sea of Cortez, and from the coast of New Zealand to South Africa.
They can also be found in other smaller locations including the Hawaiian islands, and areas of the Caribbean.
They prefer warm, shallow waters of the open ocean, and prefer coastal areas near continental and island shelves and banks, particularly in bays, estuaries and shallow reefs. Pink Manta Rays may also frequent lagoons, harbors, and protected shallow waters.
Is it ok to touch Manta rays?
Manta rays are incredible and awe-inspiring creatures, but it is not recommended to touch them as it can be stressful and even damaging for the animals.
Even if it looks safe to approach them, it is best to leave them alone and enjoy them from a distance. Not only can direct contact harm the animal, but some manta rays may also react negatively if someone attempts to touch them.
It is always important to treat wild animals with respect and understanding so they can remain safe and healthy.
Can a ray bite you?
No, a ray cannot bite you. Rays have a soft, toothless mouth that they use to filter feed, sieving plankton and other small particles of food out of the water.
Instead of biting their prey, they use a tail spine to incapacitate their food. Some species also employ their wings to flush out or confuse their prey before swooping in for the kill.
Generally, rays will only attempt to sting if they are disturbed or threatened by humans, making it extremely unlikely that you would ever be bitten by a ray.
What kills a Manta ray?
Manta rays can die from various factors such as getting injured by boat propellers, entanglement in fishing gear, water pollution, hunting for food and medicine, and ocean acidification due to climate change.
Additionally, mantas are threatened by exploitation in targeted fisheries or being caught as by-catch, being struck by vessels, getting hooked by long-line fishing gear, and even targeted by sharks. By far the biggest threat to Manta ray populations, however, is unsustainable and destructive fishing practices, such as trawling, which destroy critical habitat, disrupt ecosystems, and deplete prey sources.
Do Manta rays have feelings?
Manta rays are widely known as gentle and graceful ocean creatures. But what many people don’t consider is if these beautiful animals are capable of feeling emotions like we do.
Scientific research into animal behavior and emotion is inconclusive when it comes to manta rays, but based on their sophisticated neurological and hormonal systems, experts speculate that they are likely able to experience pleasure and stress, as well as exhibit signs of playfulness, anger, and aggression.
While we cannot be sure if manta rays feel emotions in the same way we do, their intelligence, social nature, and long-term memory indicate that they have the capacity to feel and express emotion in some form.

Final Words
Although our understanding of pink manta rays is limited, it is evident that they do not reproduce through egg-laying like other sea creatures. Instead, they use external fertilization, releasing both sperm and eggs simultaneously into the water with the aim of them coming together. This intriguing method has enabled them to survive in the wild for millennia.
