After decades of searching, six dinosaur-era creatures, similar to eels, were found by tour guide Sean Blocksidge in Margaret River, Australia. 

The creatures are equipped with powerful rows of teeth to latch on to and obtain blood from their victims.

The monstrous creatures, also known as “vampire fish,” have existed for millions of years. They exhibit elongated, gelatinous, cylindrical, scaleless, and very slippery bodies, according to The Sun Oct. 27. 

Lacking jaws, they use their specialized suction cup-shaped mouths to feed, sucking the blood of their prey to their heart’s content. They are actually lampreys—similar in appearance to eels, for which they are often mistaken.

“It was a kind of surreal moment. I had heard so many stories from the old-timers about how the lampreys used to migrate in their thousands up the waterfalls,” Blocksidge said.

He added: “I’m out on the river every day on tour with the canoes and always hoping to spot one, but this was my lucky day. Yeah, I got a bit excited – and also excited to know they are still here.”

Blocksidge, 49, told of the find that occurred at Yalgardup Falls, while guiding a tour group as he usually does.

“I looked down into the water and it looked like a long blue tube sitting in the shallows. I thought it looked a little strange, as there is really no trash in the river,” Blocksidge continued. 

He added, “I went down for a closer look only to discover another half dozen of the ‘tubes’ trying to make their way up the waterfall—It turned out it was the elusive pouched lamprey that I had been trying to find for the past 20 years!”

The tourists with Blocksidge were impressed once the significance of the find was explained to them. 

These slippery pouched lampreys live for their first few years in freshwater, then migrate to the sea, where they feed on other fish during their adult life. They then return to the rivers to reproduce and spawn before dying.

Senior researcher Stephen Beatty from Perth’s Murdoch University welcomed the discovery of the fish, commenting, “It’s great that knowledge of this unique animal has increased.

He added: “In terms of evolutionary significance, they’re a pretty amazing animal and we’re really lucky to have one of the species come up our rivers in the South West,” according to ABC. 

He also encouraged people to go out and observe them: “We encourage people, parents and kids, to get out and grab a torch on rainy winter evenings—that’s your best chance of seeing them.”

It’s not common to find creatures that have persisted on Earth since the time of the dinosaurs, however, there was another similar find recently in Arizona.

After torrential summer rain in northern Arizona next to Wupatki National Monument, three-eyed creatures called Triops reappeared. 

They were the size of a tadpole and began to thrive, swimming around a makeshift lake at the monument’s ceremonial ball field, initially a creation of the Wupatki Indian people.

“We knew that there was water in the ball court, but we weren’t expecting anything living in it,” Lauren Carter, Wupatki National Monument’s chief interpretive ranger, told Live Science.

“Then a visitor came up and said, ‘Hey, you have tadpoles in your ball field.'” So, “I just scooped it up with my hand and looked at it and was like ‘What is that?’ I had no idea,'” Carter said. And when he looked it up, he learned that the pond had become home to the extraordinary Triops.
