Harris, a doctoral prospect at the University of Plymouth, is working to understand ecological hints that trigger the fish to migrate, often hundreds of miles, in search of food. She states government officials, conservationists and scuba outfitters who lead reef manta ray-watching trips could all use such details to benefit the animals.

Those plates, made of cartilage, are lately a source of problem: Poachers are killing reef manta rays to supply quacks who peddle the product in a phony solution. That practice, plus deliberate killing of the fish for food, unintentional capture in internet, boat strikes and other dangers have reduced world populations. In the Sea of Cortez, aggressive overfishing cleaned out local populations of two reef manta ray cousins, the oceanic manta ray and the devil ray, in just 20 years.
Conservation groups are spurring research study into the slow-growing giant, which can extend 12 feet wingtip to wingtip, weigh 1,500 pounds and live 40 years. “Its a types that doesnt have any way of adjusting to endure human pressures,” says Joanna Harris, a researcher at Manta Trust, a U.K.-based nonprofit. “The only method to stop the decline is to do something about it.”
Climate Change.
Protections appear to be efficient in the Maldives, where capturing reef manta rays is forbidden and rangers restrict access to specific lagoons when the animals aggregate to feed. The island chain plays host to the worlds largest population of the majestic fish, with more than 5,000 individuals counted. The dark area pattern on the underside of each one is unique and acts as an ID. The reef manta ray in this photograph, according to a Manta Trust database, is a juvenile male. His name is Naba..

For a reef manta ray like this one swooping in the Indian Ocean near the Maldives, motion is life. Those plates, made of cartilage, are lately a source of problem: Poachers are killing reef manta rays to supply quacks who peddle the product in a bogus solution. In the Sea of Cortez, aggressive overfishing wiped out regional populations of two reef manta ray cousins, the oceanic manta ray and the devil ray, in simply 20 years.
For a reef manta ray like this one diving in the Indian Ocean near the Maldives, motion is life. Like lots of shark types, a manta ray need to constantly move to avoid sinking and to keep oxygen-rich water streaming across its gills.
