This relatively new Asian-based trade seems to be impacting the giant manta more than other species of manta ray, with the unsustainable harvesting decimating their populations around the world. The ever-increasing demand for their body parts has fuelled both existing and emerging target fisheries. Giant manta rays are targeted for their gill plates, which they use to filter feed on small zooplankton from the water column. Their current status is a direct result of unsustainable pressure from fishing, which now threatens to destabilise their populations across the globe.” “When we first assessed manta rays in 2003 there simply was not enough information on the species to determine their conservation status and they were listed as ‘Data Deficient’, but on each of the subsequent assessments, their conservation status increased steadily from Near-Threatened, to Vulnerable and now to Endangered. Andrea Marshall, a co-founder of the Marine Megafauna Foundation (MMF) who lead-authored this newest assessment for the IUCN and has been involved in their assessments since 2003. “The giant manta ray is a classic example of a species that is quickly succumbing to human-induced pressures,” said Dr. At this stage, 30% of sharks and rays are now threatened with extinction. The giant manta ray now joins over 16,000 endangered species to be assessed with this serious threat level. This is an identifying feature of this species.The International Union for the Conservation of Nature (IUCN) has announced that the conservation status of the giant manta ray (or oceanic manta ray) has been changed from Vulnerable to Endangered on the Red List of Threatened Species. Tail is whip-like and has a thick round mass at the base, just behind the dorsal fin.The patterns on the shoulders and underside exhibit many arrangements and help researchers recognize individual animals. The underside is mostly white, dotted with black or charcoal blotches. This species of manta may show great variation in pattern, but generally can be described as such:ĭorsal surface is dark in color with lighter shoulder patches.The maximum adult size is about 20 feet (6 m).Sometimes called the “devil ray” because when rolled and projected forward, the cephalic lobes have the appearance of horns.At this time the cephalic lobes will be open and extended. These lobes are usually kept rolled and pointed forward except when the manta is feeding. Has the classic manta ray body shape featuring a broad head with an enormous wide mouth flanked by two broad, flexible, fleshy lobes (cephalic fins).Beginning Environmental Leadership Program. ![]() ![]() Shows & Presentations Shows & Presentations
