Was the kraken real?

It was 1873. A fisherman was sailing in his boat. He saw something in the water. 

He sailed over and poked it with a hook. 

Suddenly, the thing rose out of the ocean. Its long arms slapped at the water. A giant tentacle landed across the small boat. 

The fisherman grabbed an ax. He cut off the tentacle! 

The huge monster let go of the boat. Then it slipped back into the water. 

The fisherman was left with the long tentacle. He was also left with a big question.

What was that thing?

Scary Stories

For thousands of years, sailors have told stories of sea monsters. The monsters in their stories were huge. They used giant arms to grab sailors and eat them. They pulled ships down to the bottom of the sea. 

The most famous of these monsters was called the kraken. For a long time, scientists could not prove these stories were true. They thought the stories were just told for fun. 

That all changed on that day in 1873.

Sometimes, dead giant squid wash up on beaches.

The fisherman went back to shore. He showed the giant tentacle to scientists. 

They studied it. 

The tentacle was evidence. It was a clue. It proved that a sea animal like the kraken was real! 

But the scientists did not think it belonged to a monster. They guessed it belonged to a kind of squid. 

Squid are ocean animals. They have eight arms and two tentacles. They have soft bodies. Most squid are not very big. They aren’t hard to find in the ocean. 

But this tentacle was 19 feet long. That could stretch to the top of a two-story building! 

This squid had to be giant.

Over time, scientists learned more about giant squid. They were sure that giant squid were real. How did they know? Sometimes, dead ones would wash up on beaches. 

Scientists studied them. They learned that giant squid have the biggest eyes of any animal. They learned that many giant squid weigh hundreds of pounds. Giant squid can grow as long as a school bus. 

They also learned why giant squid are so hard to find. Giant squid live deep in the ocean. For a long time, people were not able to go that deep under the sea. They did not have the technology to do it. 

No one had ever seen a giant squid alive. No one had seen one swim or eat. Scientists had so many questions. 

Would they ever see a living giant squid? Could they even get a photo of one under the sea?

Squid Squads

Squid Squads

In the 1960s, people invented new submarines that let them go deep into the sea. At last, scientists could go thousands of feet underwater. Teams of scientists started searching for giant squid. They called themselves “squid squads.”

Years went by. The scientists saw amazing animals that no one had seen before. But they could not find a giant squid.

Proof!

Proof!

Proof!

In 2004, a team of scientists had an idea. They knew that some whales eat giant squid. They followed those whales. They hoped this might be a way to see a giant squid.

The scientists sent a camera deep underwater to where the whales lived. Then they watched and waited, hoping a giant squid would be near.

At last, they saw a large animal. It was as long as a school bus. Its eyes were as big as basketballs. And it had eight long arms and two tentacles. It was a giant squid! 

It waved its arms. The camera took more than 500 pictures. Scientists finally had photos of a living giant squid!

Since then, scientists have taken videos and more photos of giant squid. 

They are learning more and more about these incredible animals. But they still have so many questions. How many are there in the oceans? How old can they get? How deep in the ocean can they swim? 

Maybe someday, you’ll be the one to answer them!
