The name can be explained from Latin mobilis "mobile" or "movable", because of the species' migratory habits another explanation is that mobula is a local name used by people living in Azores who call this creature there. The genus is named by Constantine Samuel Rafinesque in 1810 describing the devil fish, Raia mobular or now Mobula mobular. In most species having a stinger, it is encased, rendering it harmless only M. Most species entirely lack a tail stinger. Despite their size, little is known about the devil rays, much of it anecdotal the manta rays are better known. ĭepending on the species, the devil rays can attain widths up to 1.1–5.2 m (3.6–17.1 ft), the largest being second only to the manta rays in size, which can reach 5.5–7.0 m (18.0–23.0 ft). These rays gather in groups and leap out of the surface into the air up to around two metres before splashing back into the water. Species of this genus are often collectively referred to as "devil rays", "flying mobula", or simply "flying rays", due to their propensity for breaching, sometimes in a spectacular manner. Their appearance is similar to that of manta rays, which are in the same family, and based on genetic and morphological evidence, the mantas belong in Mobula (they are traditionally in their own genus Manta). Some authorities consider this to be a subfamily of the Myliobatidae (eagle rays). Although they are protected in international waters and by laws of certain countries, they travels often through unregulated waters and are still being fished all over the world.Mobula is a genus of rays in the family Mobulidae that is found worldwide in tropical and warm, temperate seas. Overfishing has the real potential to wipe out large numbers of giant oceanic mantas due to the fact that they live so long and reproduce so little. Their size make them particularly susceptible to entanglement in fishing nets even when they are not voluntarily fished out. Their gills is still in high demand mostly by the traditional chinese medecine market. The Manta Trust and Marine Megafauna foundations are both working globally to research and protect the mobulae family and their habitats. The International Union for Conservation of Nature (IUCN) declared manta rays as ’vulnerable’ in 2011. All of this combined make their reproduction quite slow! The mother will usually have two years elapse between pregnancies. Manta-mums usually carry only one pup, but 2 pups have already been recorded. They are born independent after a 12-13 months gestation period. Manta rays can live as long as 50 years and are ovoviviparous, which means that they start development in an egg and hatch within the mother's body.
