![]() ![]() Some studies investigate whether remoras slow down their hosts due to increased drag, but it appears the remoras’ streamlined bodies evolved to make sure they are successful hitchhikers that don’t place extra energy demands on their hosts.Īmazing, cooperative relationships between species exist throughout the animal kingdom and especially the ocean. Other predatory sharks big enough to conceivably prey on mantas include the great white, which exceeds six meters (20 feet) in length the swift mako sharks the oceanic whitetip, among the tropical open ocean’s most widespread predators and the great hammerhead, which has a taste for rays. Without the remoras, manta rays would likely have to stop at coral reefs more frequently to have scavengers like shrimp and even smaller fish clean their skin instead. In return, the manta ray gets a personal spa treatment from the remoras attached to it as they clean the manta’s skin of bacteria and parasites, which keeps their host healthy. Scientists say the giant manta ray, known as a gentle leviathan, is in fact a predator of the deep preying on fish and other animals. The remora’s ability to suction causes no harm to the manta rays and doesn’t even make lasting changes to their skin tissue. Manta rays are filter feeders that have no interest in. Due to overhunting and other human industrial activities, the IUCN (International Union for Conservation of Nature) lists the giant manta ray as Endangered. ![]() However, you should never get within touching distance of a manta ray, as touching one can cause them serious harm by damaging the protective film they have on its skin. 7 min read The giant manta ray, also known as Mobula birostris or Mantra birostris among scientists, is one of the 630 different species of ray known to humankind. Noticeably, the mantas possess wide cavernous mouths and a large wingspan of up to 12-14 feet ( reef mantas) / 22 feet ( pelagic mantas ). There are many misconceptions when it comes to these marine animals, mainly due to the sheer size and shape of their body. Luckily, manta rays are messy eaters (you would be too if your mouth was wide open all the time!) and leave behind trails of food scraps that the remora can also benefit from. These gentle giant rays are completely safe for humans to be around, they are even quite friendly and curious toward us. At Manta Ray Advocates, we refer to mantas as the ‘gentle giants of the sea’. In this case, remoras cling to the manta ray’s body (often on the underside, but sometimes on its dorsal side) for protection, easy transportation, and feeds when the manta ray glides into plankton-rich waters. Mantas and remoras have what biologists call a mutualistic relationship, meaning both animals benefit from each other. Manta ray and remoras in Flower Garden Banks National Marine Sanctuary.
