It is caught for food by artisanal fishers in Latin America, particularly in Mexico where it is one of the most economically important rays. This is assessed as Vulnerable by the International Union for Conservation of Nature (IUCN). Though innocuous towards humans, the diamond stingray's long, venomous tail spine is potentially dangerous.
They are dangerous to the environment because they eat almost everything, destroying many habitats. The lack of natural predators led to overpopulation, which had a huge impact on the Galápagos tortoise, driving the tortoises near to extinction. [4] Fixing invasive species problems is difficult and expensive. [5]
Spotted eagle rays, in common with many other rays, often fall victim to sharks such as the tiger shark, the lemon shark, the bull shark, the silver tip shark, and the great hammerhead shark. [ 28 ] [ 29 ] A great hammerhead shark has been observed attacking a spotted eagle ray in open water by taking a large bite out of one of its pectoral ...
Most particularly, the continuing decline of threatened rays and sharks is the consequence of unregulated fishing, [10] as illustrated by a recent international survey which listed only 38 species of skates and rays still subsisting in the highly impacted Mediterranean Sea. [11] Sawfish are a family of rays which have a long rostrum resembling ...
Feral goats are dangerous to the environment because they eat everything in sight, destroying many habitats. These goats did not have natural predators, thus their population continued to grow, which led to a decrease in native organisms they prey on. The goats had a huge impact on a specific species on the island, the Galapagos tortoise. The ...

[55] Historically, mantas were feared for their size and power. Sailors believed that they were dangerous to humans and could pull ships out to sea by the anchor.
In addition, while traditional phylogenies often find electric rays to be the basalmost batoids, followed by the Rhinopristiformes, this analysis finds a polytomy between skates, electric rays, and thornbacks at the base of Batoidea, with weak support for skates being the actual most basal lineage, followed by a clade uniting the electric rays ...
