These include: The Bahamas, Mexico, The Cayman Islands, Spain, Fiji, Thailand, Indonesia, Hawaii, Western Australia, and the Maldives. While they prefer warmer waters, they have to follow their next meal! The sites with denser populations attract many tourists. Manta Rays can be found in all oceans apart from Arctic and Antarctic zones. However, juvenile Manta Rays need to avoid large Sharks and Killer Whales. This Ray’s speed, size, and tough exterior make it a difficult and unappetizing meal for many large predators. Because of this, it has very few natural predators. The Manta Ray is an apex predator at the top of its food chain. Watching these friends hunt is a fascinating sight, as they have been seen forming cyclones in the water to trap food in a single spot. These small fish are sifted through the rakes that line their mouths, also known as gill plates. Much like the Blue Whale, the Manta Ray is a well-known filter feeder! Our friends hunt by swimming with their mouth open, trapping zooplankton and krill. These hotspots include tropical waters such as Mexico, Hawaii, and Thailand. These Rays are often loners but have been seen congregating in large numbers where food is plentiful. Their daily migrations can still cover a lot of ground, approximately 70km in search of plankton and other small fish. The Reef Manta Ray earned its name “Resident Manta Ray” by being less migratory, staying closer to the coastline. These are often streamlined currents, allowing the Manta Ray to travel 1,100km in a straight line! Because Manta Rays enjoy eating plankton, they often follow the currents that carry their prey. The Giant Manta Ray migrates more than the Reef Manta in search of warm, temperate waters. With no trouble at all, these friends can reach 14 km/h, which is nearly double the speed of Michael Phelps! If they want to go faster, they can easily reach speeds of 35 km/h. The Manta Ray is a smooth operator, gliding effortlessly through the ocean currents. These heightened senses allow the Manta Ray to easily detect prey hidden under the seafloor. These ampullae detect electric signals from other fish and create an aura around them. They also have a strong sense of hearing and smell, which is supplemented by their ampullae of Lorenzini. This includes a lateral line system, which allows them to feel currents created by distant prey.

They also cannot see while they are eating because their mouth is directly under their blind spot. Their eyes are located on each side for panoramic vision, with the drawback of blind spots directly in front and behind. Scientists are unsure how well Mantas can see, as they rely on scent to seek out prey. The sound has been observed as a high pitched, bubbling screech. This is unusual considering their Shark cousins lack this ability. Manta Rays have been known to project “battle cries” when attacking prey. What type of vision does the Manta Ray have, and what sounds do they make? The Reef Manta has a Y shape, while the Giant Manta has a T shape. To spot the difference between species, you must pay attention to their white dorsal lines. The visual similarity between these two species causes juvenile Giant Mantas to be often mistaken for Reef Mantas.īoth of these rays sport the colours black, dark brown, and grey-blue. Giant Manta Rays can weigh up to 3,000kgs, while Reef Mantas can weigh up to 1270kgs. The Giant Manta is the largest Ray in the ocean: with a wingspan of up to 7 meters! The Reef Manta Ray is smaller, with a maximum wingspan of 5 meters. The Manta Ray: Out of the Blue! Photo by Emma Li on What is the size, weight & colour of the Manta Ray? Additional research on our friends’ intelligence in the future will surely uncover fascinating results. Because they are so large, very few are kept in captivity, limiting observations to ocean-bound Rays. The Manta Ray is still a marvel and mystery to many scientists. Manta Rays have been observed creating mental maps of their environment through visual cues and scent! The most impressive function is their highly developed long-term memory. This gives them the same high cognitive function that can be found in Dolphins, Primates, and Elephants. Our friends are more than just a pretty face! They have been found to have the largest brain (relative to body size) out of any cold-blooded fish. Giant Manta Rays inhabit all the world’s oceans, and the Reef Manta Ray, inhabits the Indo-Pacific Ocean. There are two species of this friendly ocean dweller in the Mobulidae family. Its intricate black designs differentiate it from all others and vary depending on where it lives. The Manta Ray is a large, distinct Batoid.
