It may sound dangerous to try as stingrays will occasionally bite, but this woman isn't even nervous as she holds her hand out to a wild stingray's mouth over and over again.

And the stingray keeps coming back for more fish. You can just feel Indy the dog getting jealous as he runs up to try and sniff the stingray. He probably didn't get that many snacks in a row.

Though stingray tours have become a more common vacation experience, there isn't a clear verdict on whether they are completely safe. Australian naturalist Steve Irwin, known as the 'crocodile hunter,' was killed by a stingray while taping an underwater documentary.

Yet, many experts claim that stingrays are gentle creatures that only attack out of self-defense. But, they don't like being stepped on, literally, and will bite ankles and lower legs when people accidentally step on them while underwater.

Would you be up for trying to hand-feed wild stingrays or more daringly have a go at feeding wild cougars?

Maybe a stingray photobomb is more your idea of a fun vacation takeaway.

    FILE - In this undated file photo released by Conservation International, a healthy coral reef is seen off the Caribbean island of Bonaire. The International Union for Conservation of Nature says the Caribbean's reefs are in sharp decline, with live coral coverage down to an average of just 8 percent, in a report released Sept. 7, 2012. That's down from 50 percent in the 1970s. (AP Photo/Andy Bruckner, NOAA Fisheries, File)

Scientists using cutting-edge technology to explore waters off Indonesia were wowed by colorful and diverse images of marine life on the ocean floor _ including plate-sized sea spiders and flower-like sponges that appear to be carnivorous. They predicted Thursday Aug. 26, 2010 that as many as 40 new plant and animal species may have been discovered during the three-week expedition that ended Aug. 14.

A study by The National Oceanic and Atmospheric Administration (NOAA) says Americans value coral reefs around the main Hawaiian Islands at the amount of $33.57 billion. Researchers arrived at the figure by surveying 3,200 Americans across the nation and asking them how much of their income taxes they would want devoted to hypothetical initiatives to improve the health of Hawaii's coral reefs.

    TO GO WITH AFP STORY BY PIERRE PRATABUY A scientist diver discovers the flora and fauna located on artificial reefs, by 30 meters deep (98.42 ft) on July 8, 2012 off shore of southern city of Marseille. The immersion in 2008 of nearly 30,000m3 (1.059.439 ft3) of artificial reefs in the bay of Marseilles rose to a return of the species. The presence of such some 200 hectars (494 acres) of artificial habitat for flora and fauna, located between the islands of Friuli and the Prado Bay, is 'the largest artificial reef made ??up in Europe,' said Didier Reault, French right wing party Union for a Popular Movement (UMP) City delegate to boating, beaches and national park of the Calanques. A Big Blue in a 'good ecological status' in 2020 ? This is the aim of the Water Agency and of the Interregional Sea Directorates (DIRM), a French Minister of Ecology Department, providing a financing project of 600 million euros (737 millions dollars) over six years including 6 millions (7.37 millions dollars) to raise awareness.

  • Environmental Groups Challenge Navy's Use Of Sonar In West Coast Training Exercises

    ABOARD THE MANUTEA, CA - JANUARY 30: Bottlenose dolphins swim ahead of the bow of a boat off the southern California coast on January 30, 2012 near Dana Point, California. A coalition that includes Native American tribes, Earthjustice and the Natural Resources Defense Council is on the National Marine Fisheries Service for more protection for dolphins, whales, and other migrating marine animals from the use of sonar in training by the US Navy on the West Coast. Environmental groups argue that mid-frequency sonar alters the behavior of sound-sensitive marine life and, in some cases, causes fatal results. Some whales are believed to communicate across hundreds of miles of ocean through sound. (Photo by David McNew/Getty Images)
