Researchers from James Cook University were tagging marine life on the northeast coast when the 3m tiger shark they caught vomited up a dead echidna.
Nicolas Lubitz, a PhD candidate who studies marine predators, said he could only assume the shark gobbled up the echidna while it was swimming in the shallows off the island, or travelling between islands, which the animals are known to do.
I am impressed the shark got it out again and didn’t end up with a permanent internal echidna spine collection.
