Tourists visiting Australia got a rare look at the stunning power of sharks feasting on a massive whale carcass. Posted at the Facebook page of the Eco Abrolhos tour company in western Australia, a video taken by an overhead drone offers a view of packs of hungry tiger sharks feeding on a hapless whale. Sharks can been seen circling and swimming around the huge body of the whale that they were reducing, bite by bite, to unrecognizable flotsam and jetsam.
The beautiful turquoise waters of an Australian reef were marred by streams of blood and gore from the dead whale as two tour boats filled with passengers were nearby. Striking aerial shots of the carnage showed the nearly transparent water teeming with hungry sharks.
The Eco Abrolhos tour company wrote that the video was recorded near Dirk Hartog Island during a 14-day cruise. Dirk Hartog Island is a constituent part of the Shark Bay World Heritage Site. The area is home, not only to sharks, but also other sea life such as sea cows. There are seagrass beds there that are home to breeding populations of fish that are prey to the sharks. Tiger sharks can grow to more than 18 feet long and are considered a threatened species. Overfishing by ships, mostly from China and Taiwan, seeking shark fins have devastated whole regions of the Pacific and Indian oceans.
Tiger sharks, Galeocerdo cuvier, are widely distributed in tropical and sub-tropical waters. They are found close to the coastal areas throughout the world. They are primarily nomadic, and follow warm currents. It stays near the Equator during cold months of the year. While it may stay in deep waters that lie along reefs, they do move into channels and shallows. In Hawaii, for example, they have been found are depths of less than 10 feet. They are common in the Gulf of Mexico, and along the beaches of North and South America. A tiger shark tagged in the Caribbean, for example, has been tracked migrating to Cape Cod, Massachusetts. They are found also in Africa, China, Australia, Indonesia, India, and Hong Kong.
