In a shocking and unprecedented event, a tiger shark was observed vomiting up a dead echidna off the coast of Orpheus Island in Australia's North Queensland region in May 2022. The incident was witnessed by a team of researchers from James Cook University, who were conducting a marine life tagging expedition.
The echidna, a spiky, egg-laying mammal that is native to Australia and New Guinea, was found to be whole and intact when it was regurgitated by the three-meter-long tiger shark. The shark, which was not harmed in the encounter, was released back into the water after being fitted with an acoustic tracker.
This unusual event is believed to be the first recorded instance of a tiger shark consuming and regurgitating an echidna. Tiger sharks are known for their voracious appetites and have been documented eating a wide variety of prey, including turtles, birds, sea snakes, and even small vehicles. However, echidnas are not typically found in the ocean and are not a common food source for tiger sharks.
The researchers suggest that the echidna may have been swimming in the shallows or between islands, where it was caught by the tiger shark. The shark's regurgitation of the echidna may have been due to the spines on the echidna's body, which could have caused discomfort or pain in the shark's digestive system.
This unusual discovery provides valuable insights into the feeding habits and behavior of tiger sharks and highlights the importance of continued research into the marine ecosystem.
