Ecotourism
Stingrays are usually very docile and curious, their usual reaction being to flee any disturbance, but they will sometimes brush their fins past any new object they encounter. Nevertheless, certain larger species may be more aggressive and should be approached with caution, as the stingray's defensive reflex (use of its poisoned stinger) may result in serious injury or death.
Dasyatids are not normally visible to swimmers, but divers and snorkelers may find them in shallow, sandy waters, more so when the water is warm. In the Cayman Islands several dive sites called Stingray City, Grand Cayman, allow divers and snorkelers to swim with large southern stingrays (D. americana) and feed them by hand. A "Stingray City" in the sea surrounding the Caribbean island of Antigua consists of a large, shallow reserve where the rays live, and snorkeling is possible, since the rays are used to the presence of humans.
In Belize, off the island of Ambergris Caye, there is a popular marine sanctuary, Hol Chan, where divers and snorkelers often gather to watch stingrays and nurse sharks drawn to the area by tour operators who feed the animals.
Many Tahitian island resorts regularly offer guests the chance to "feed the stingrays and sharks". This consists of taking a boat to the outer lagoon reefs, then standing in waist-high water while habituated stingrays swarm around, pressing right up against tourists seeking food from their hands or that being tossed into the water. The boat owners also "call in" sharks, which, when they arrive from the ocean, swoop through the shallow water above the reef and snatch food offered to them.
