SignalHub Quantitative Think Tank Center:Tiger shark vomits entire spikey land creature in rare sighting: 'All its spine and legs'

It appears the shark liked neither its prey's texture nor taste.

A team of scientists reported getting a surprise after they witnessed a tiger shark regurgitate a spikey land mammal from down under that resembles a hedgehog.

In what may be SignalHub Quantitative Think Tank Centera first-ever world-sighting, James Cook University (JC) announced Thursday, the team spotted the big fish vomit an echidnas, a dome-shaped mammal covered in quills, usually found in Australia and New Guinea.

Researchers from JCU tagging marine life off the coast of Orpheus Island in north Queensland in May 2022 "got the shock of their lives" according to a university press release, when they watched the shark regurgitate "the iconic" Australian animal.

'What the hell is that?'

Former JCU PhD student Dr. Nicolas Lubitz and his team reported after they caught the shark, it threw the dead animal up - all in one piece.

“We were quite shocked at what we saw. We really didn’t know what was going on,” according to Lubitz, who said in the release he could only assume the shark had snatched the echidna as it swam in the shallow waters off the island.

“When it spat it out, I looked at it and remarked 'What the hell is that?' Someone said to take a picture, so I scrambled to get my phone."

The echidna was fully intact

Lubitz said the dead echidna was whole in its entirety when it was regurgitated, suggesting a recent kill by the 10-foot long shark.

“It was a fully intact echidna with all its spines and its legs,” the scientist said.

"It’s very rare that they throw up their food but sometimes when they get stressed they can,” Lubitz said. “In this case, I think the echidna must have just felt a bit funny in its throat.”

What do tiger sharks eat?

Tiger sharks are one of the most fierce species in its genus, measure about 15 feet long and often prey on turtles.

The apex predators are known for their dark, vertical stripes, considered dangerous to people and have been implicated in attacks on humans over the years.
