Giant manta ray size comparison1/23/2024 ![]() Feeding chains – This is a technique done by a group of manta rays.Bottom-feeding – Feeding on the seabed where the concentration of zooplankton is high.Somersaulting – Circling their prey to optimize their food intake.Surface feeding – When they swim, manta rays open their mouth to swallow large numbers of zooplankton.They also follow feeding strategies which will be discussed below. This means that they filter the food they eat through their gill plates and by using cephalic fins that resemble horns. How Manta Filter Feeders Eat Their Prey?Īs cited from one study in the USA, Manta rays are filter feeders. Interestingly, they can eat up to 5 kgs of these foods per day. Other prey these marine animals also consider include the following:Īside from small food, manta rays also feed on medium-sized fish. Some of these abundant microscopic organisms include krill and mysid shrimp. Like the largest mammals, blue whales, manta rays feed on zooplankton. Again, this is one of the factors in how they choose their habitat – depending on the abundance of food sources. There are areas that manta rays consider as their feeding stations. In terms of lifespan, manta rays are thought to live up to 40 years. Research suggests that manta rays come with a very low reproduction rate but the mortality of the pups born is low as well. When female manta rays give birth, they typically bring out 1-2 pups. If you wonder how you will know that mating has been successful, there are bite marks left in female manta rays.Īdditionally, the gestation period of manta rays is around one year. This is the reason why they can become extinct easily. Mating will then last for several minutes until the male manta releases the female.īoth species of manta rays can only breed for up to 5 years. Then, a male manta will insert one of its claspers into the vent of a female. According to a study from Australia, after chasing female manta rays, a male manta ray will pinch one of the female’s pectoral fins to stop it from swimming. Male manta rays court by following the females. Courtship, Reproduction, and Lifespan of Giant Mantas and Reefs At night, these manta species are reported to be moving into deeper waters. When reef mantas are in these locations, their movement is limited. Additionally, this choice is associated with mating, food abundance, and currents. According to National Geographic, it was in early 2008 that this species was discovered.īased on researchers from the USA, Saudi Arabia, and France, reef manta rays prefer near-shore tropical and subtropical waters. Manta alfredi or reef manta rays are smaller than the first species discovered. When they move out, they swim by flapping their pectoral fins. Their behavior includes staying on those surfaces for a considerable time. According to a study from the Journal of Fish Biology, giant manta rays prefer warmer waters because food sources are more abundant. Manta birostris is usually found in offshore islands or mid-waters of reefs at depths of around 120 meters. According to the Florida Museum, this species was the first species known, discovered in 1978. Manta BirostrisĪlso known as giant manta rays, this species can be identified because of its casual thorn and rough skin texture. There are two main species of manta rays and in this section, we will elaborate on these species and how they differ from one another. The dorsal side of manta rays is darker and the ventral side is mixed with black and white spots.Īlso based on the NOAA, these spot patterns on their bellies are used for identification. ![]() Generally, the average manta ray’s body size is around 15 feet., and may come in two colors such as chevron and black. ![]() ![]() They have large mouths with two cephalic lobes in front.The word “Manta” means blanket or cloak in Spanish, defending the characteristics or physical appearance of these marine animals: According to the National Oceanic and Atmospheric Administration (NOAA), manta rays also have an internal skeleton of cartilage. ![]()
