Ocean eddies are coherent, rotating features which are ubiquitous at mid-latitudes and rotate clockwise In the Northern Hemisphere.
As these anticyclonic eddies move throughout the open ocean, a recent study suggests that the predators are also moving with them, foraging on the high deep-ocean biomass which tends to accumulate within.
Although manta rays are readily capable of long-distance movements of hundreds if not thousands of kilometres, most populations appear to be philopatric (tending to return to or remain near a particular site or area—ed.) with few examples of long-distance dispersal.
Oceanic manta rays, the largest ray species, were listed as threatened under the U.S. Endangered Species Act in 2018. In 2019, their threat category increased from vulnerable to endangered on the International Union for the Conservation of Nature’s Red List.
Up to 12 passengers can experience electric hydrofoiling in the Candela P-8. It has one electric pod motor, which allows the P-8 to cruise in almost complete silence, so it does not disturb marine wildlife or contribute sound pollution.
