The most obvious reason they form groups is to catch prey and gather at the cleaning stations. Manta rays form social groups for different reasons. Scientists don't fully understand manta rays, but they believe manta rays have social groups. Wrasse receive nourishment while providing a helpful cleaning to the manta rays. Wrasse and manta rays have a symbiotic relationship. Manta rays stop by the Wrasse “cleaning stations” on a regular basis. Wrasse fish that live in coral reefs clean manta rays of parasites and dead skin. Manta rays have an important relationship with coral reefs. They swim around with their mouths wide open, sifting plankton with their modified gills. Manta rays travel short distances away from the reef to feed. They stay near the surface during the day, and dive deeper at night for food. Reef manta rays are active both during the day and at night. Reef manta rays can be seen in bays and around offshore islands near coral and rocky reefs. They live in the tropical and sub-tropical waters of the Indian and Pacific oceans. Reef manta rays are found throughout the shallow coastal waters of the Indo-Pacific region. There are a few white manta rays, and one pink manta ray has been seen. The black and white mantas have black tops and white bellies with dark spots. Manta rays are typically black and white or all black. Female manta rays are usually larger than males. Mantas typically weigh almost three thousand pounds. A reef manta ray’s average disc size is about eleven feet. Manta rays are measured by their disc size due to their shape. A manta has a long tail that looks like a whip. It also has two fins that stick out from the front of its head that resemble horns. There is one pectoral fin on each side of a manta ray’s body.Ī manta ray has two eyes located on each side of its head. These fins look like big, flapping wings. Manta rays have two flat, massive, triangular-shaped fins. The body of a manta ray is shaped like a diamond. Manta rays have wide heads and flat bodies. This article will focus on the reef manta ray species. Read here to learn about the three main differences between the two species. The two species are giant manta rays and reef manta rays. The recording was broadcast by NHK, Japans national broadcaster, on Sunday 17th June, showing the newborn female emerging "rolled-up" from its mother, before spreading out its 1.9m-wide fins.There are two species of manta ray. The birth of the Giant manta ray was witnessed, and recorded, by staff at the aquarium. Noriyasu Suzuki, of the Izu-Mito Sea Paradise commercial aqua zoo in western Japan, told the Washington Post that "aquariums that raise manta rays are rare to begin with", and so to have a successful captive birth from a mating that took place within the aquarium itself is a big achievement for the Okinawa Churaumi Aquarium. The mother is 4.2m in width, and was taken in by the aquarium in August 1998 after hitting a fishing net off the island of Okinawa. The father, who is 3.5m in width, has been at the aquarium since May 1992. Minoru Toda, of the Okinawa Churaumi Aquarium, told the Washington post that they hope to learn more information about the species through making "sure the baby grows in good health."Īquarium successThe parents of the young Giant manta ray are long-term inhabitants of the Okinawa Churaumi Aquarium. Mating was observed in the Kuroshio tank at the aquarium on June 8th 2006, meaning that the pregnancy took a total of 374 days. However, a lot of information on the species is still unknown to science - and, with this being the first captive birth of a Giant manta ray, the staff at the aquarium hope to record some valuable data.Īlready for the first time, the duration of the pregnancy of the Giant manta ray is known. Valuable biological dataThe Giant manta ray is known to be the largest species of Manta ray, with the potential to attain a width of 6.7m. They are still only one of a few in the world managing to do so successfully. This is a second Manta ray-first for the Okinawa Churaumi Aquarium, which was the first public aquarium to keep these Manta rays in captivity almost 20 years ago when they started in 1988. The newborn Giant manta ray, a female, was 1.9m (over 6 ft) in width at birth " almost half the size of its mother! The birth of a Manta ray in the Okinawa Churaumi Aquarium in Japan on Saturday night is believed to be a world-first in captivity. ![]()
