It was a chilly fall day in 1873. A fisherman was happily sailing near Canada. The water was still and calm. Then he saw something floating near his boat. What could it be?

He sailed toward the object and poked it with a hook. The thing moved. Suddenly, a giant creature rose out of the ocean. It looked like a monster from a scary movie. It waved its tentacles wildly. One of them landed on the boat. 

The fisherman was terrified. But he acted fast. He grabbed an ax and chopped off the tentacle. The beast let go of the boat. Then it disappeared underwater. The sea was quiet once again. 

The fisherman was left with a 19-foot tentacle and a big question: What was that mysterious sea monster?

Scary Stories

For thousands of years, sailors have told stories of sea monsters. Some were huge beasts. They grabbed sailors with their giant arms and ate them. They pulled ships down to the bottom of the sea. 

The most famous was a squid-like monster called the kraken. Some said it was larger than a whale. Some said it was stronger than an elephant.

For years, scientists didn’t believe these stories. They thought they were just tall tales—stories that are exaggerated to make them more interesting. This all changed in 1873. 

Sailors have told stories of sea monsters for years. The most famous was a squid-like beast. It was called the kraken. Scientists didn’t believe the stories. This changed in 1873.

The fisherman’s tentacle was a piece of evidence. It proved that the kraken, or something like it, was real! Scientists guessed the tentacle was from a kind of squid. 

Squid are sea animals. They each have eight arms and two tentacles. Most aren’t very big.

But the fisherman’s tentacle was 19 feet long. This new creature had to be huge. Scientists had a question. Why hadn’t more people found these giant squid?

It Was Real


The fisherman showed the tentacle to scientists. The experts studied it carefully. The tentacle was a clear piece of evidence. It proved that the kraken—or something like the kraken—was real! Part of the mystery was solved. Experts guessed that the tentacle belonged to a type of squid.

Squid are sea animals with soft bodies. They each have eight arms and two tentacles. Most squid are found all over the ocean, and they aren’t very big.

The fisherman’s tentacle was enormous, though. It was long enough to stretch to the top of a two-story building. This new creature had to be huge. Scientists were puzzled. They wondered: Why hadn’t more people found these giant animals?

Over time, scientists learned more about the creature we now call the giant squid. Experts learned that giant squid truly are giant. They have the biggest eyes of any animal. They can weigh 1,000 pounds and be almost 60 feet long. That’s longer than a school bus!

Experts also learned why giant squid are so hard to find. The creatures live thousands of feet below the surface of the ocean. For a long time, people weren’t able to go that deep under the sea. 

This changed in the 1960s. Oceanographers finally had the tools to go thousands of feet underwater. They saw wonders no one had ever seen before. There were eyeless fish and human-sized worms!

Teams of scientists formed “squid squads” to look for giant squid. But no one saw the elusive animal.

Meet a Giant Squid 

 

Its EYES are as big as basketballs. It has 8 ARMS. It has 2 TENTACLES. The arms and tentacles are covered with SUCKERS. The suckers have sharp edges like teeth.

Another Attack

Another Attack


Years passed. Every so often, more clues to the mystery would appear. Dead creatures with long arms would wash up on beaches. Giant tentacles would get caught in fishing nets. But still, no one found a live giant squid.

Then, on a dark night in 2003, a giant squid was seen again. This time, it attacked a ship full of sailors. The boat rattled and shook. The sailors ran up and down the deck, shining flashlights into the water.

Then they saw it: An enormous, slimy arm wrapped itself around the ship. The sailors thought the boat would snap into pieces. But then the creature was gone.

A BIG Surprise 

In 2018, the body of a giant squid washed up on a beach in New Zealand. It was 13 feet long. Some giant squid are nearly five times this size!

Pictures at Last


A year later, a team of scientists had an idea. They learned that some whales eat giant squid. They followed a group of these whales, hoping the whales might lead them to a giant squid.

The scientists sent a camera deep underwater. Then they waited, hoping a giant squid was nearby.

Finally, they saw something. It was longer than a school bus. Its eyes were as big as basketballs. It had eight long arms and two tentacles. It was a giant squid! 

The creature waved its tentacles wildly. The camera snapped more than 500 pictures. Scientists finally had photos of a live giant squid!

The Mystery Continues

Since then, more people have seen giant squid. We now have videos of the creatures too. Scientists continue to learn more about these incredible animals. But they still have so many questions. How many giant squid are there? How old do they get? How deep in the ocean can they go? 

There is so much more to learn about giant squid—and the ocean. The ocean is a giant underwater world. Most of it still hasn’t been explored. Experts say there are more mysterious creatures just waiting to be discovered. Maybe you’ll be the one to find them!

Scientists learned that some whales eat giant squid. This gave them an idea. In 2004, they followed the whales. They hoped the whales would lead them to a giant squid.

The idea worked! Scientists sent a camera underwater. It found something longer than a school bus. It was a giant squid! The camera took more than 500 pictures.

Since then, other people have seen giant squid. We’ve learned more about the animal. But we still have questions. How many giant squid are there? How deep in the ocean can they go? We have a lot to learn about the ocean too. Experts say more mysterious creatures are out there. Maybe you’ll be the one to find them!

Here at Storyworks 3, we’re fascinated by stories of mysterious creatures. Some of us are certain that Bigfoot exists, so we wrote “The Search For Bigfoot” to outline the evidence that’s been collected so far. And while the famous lake in Scotland has been searched thoroughly, we’re not ruling out the existence of the Loch Ness Monster. Have your students weigh in after reading “The Legend of the Lake Monster.” Ask: How are these creatures different from, and similar to, the giant squid?

 

What about mysterious creatures from another planet, you might ask! We’ve got you and your students covered there, too. Share “Are Those Aliens?” from our March/April 2022 issue and discuss whether these UFOs could actually be from out of this world.

Step-by-Step Lesson Plan

Table of Contents

Preview Text Features/Set a Purpose for Reading

  • Help students prepare to read the article by showing the Background Builder Slideshow. 
  • Ask students to predict what this article will be about based on the headline, subhead, and images on pages 4-5. Review the predictions after reading.
  • Call on volunteers to read aloud the Think and Read box on page 4 and the Think and Write box on page 9. 

Introduce Vocabulary

  • Inform students that squid is both the singular and plural form of the word. The word squid is used whether talking about one, or more than one, of these sea creatures.
  • Show or assign the Vocabulary Slideshow to preview challenging words. Then assign the Vocabulary Skill Builder before or after reading.

2. Close Reading

Reading and Unpacking the Text

  • We offer several reading experiences for this article: the Video Read-Aloud, an audio Read-Aloud, and the printed article in the magazine or digitally at storyworks3.scholastic.com.
  • Read the story as a class. Use the Pause and Think questions at the end of each section for a quick comprehension check. 
  • Project or assign the Close-Reading and Critical-Thinking Question. (Alternatively, assign all or part of the Learning Journey Slide Deck.) 

Close-Reading Questions

  • In the first section, the authors describe the creature that attacked the fisherman’s boat as a “mysterious sea monster.” What details support this description? (text evidence) Details that support this description include: a giant sea creature suddenly came up from the ocean; it looked like a movie monster; “it waved its tentacles wildly;” “the fisherman was terrified.” 
  • Read “Scary Stories.” What is the kraken? (key details) The kraken is a creature that sailors told stories about. It’s huge and squid-like. The kraken is said to be larger than a whale and stronger than an elephant.
  • Read “It Was Real.” Why is this a good title for this section? (interpreting text, text features) “It Was Real” is a good title because this section describes how the tentacle was a piece of evidence that proved that a giant squid-like creature really exists. 
  • Read “Hard to Find.” What are some details that explain how giant squid got their name? (text evidence) Giant squid have the largest eyes of any animal and can weigh almost 1,000 pounds. They can grow to be about 60 feet long.
  • Read “Another Attack.” What is this section mainly about? (main idea) This section is mainly about what happens when a giant squid attacks a ship in 2003.
  • Read “Pictures at Last.” How did scientists solve the problem of where to find giant squid? (problem and solution) Scientists solved the problem of where to find giant squid by following a group of whales. They had learned that these whales eat giant squid. The scientists thought that following the whales would lead them to a giant squid. And the plan worked!
  • Read “The Mystery Continues.” Why do scientists want to keep studying the ocean? (key idea, key details) Scientists want to keep studying the ocean because most of it hasn’t been explored. It’s a huge underwater world. Scientists believe there are more mysterious creatures to discover there. Plus, they have questions about the giant squid that they don’t yet know the answers to.

Critical-Thinking Question

  • When you grow up, would you want to become a scientist who studies the ocean and the mysterious creatures that live there? Explain your answer using details from the article and the text features. (connecting to the text, text features) Answers may vary. 

3. Skill Building and Writing

  • Distribute our Text Evidence Skill Builder and have students complete it in class or for homework.

  • Discuss the writing assignment in the Think and Write box on page 9. 

Differentiate and Customize
For Striving Readers

Work together with students in a small group. As you read the article, prompt students to use one color to highlight text evidence that shows why some people have believed that a giant monster exists in the ocean. Then prompt students to use a different color to highlight text evidence that shows how scientists proved the monster was real. Tip: When students read the articles online in Presentation View, they can use the highlighter tool to mark the text.

For Multilingual Learners

The kraken, Bigfoot, and the Loch Ness Monster may be unfamiliar to your multilingual learners. Have them read or listen to the lower-Lexile version of the article. After reading, work with the class to make a list of words that describe the creatures. Encourage students to refer to the illustrations and images as well as the article text when coming up with descriptive words. Ask students to share the names and descriptions of similarly mysterious creatures with which they’re familiar.

For Advanced Readers

Direct students to our October/November 2021 Big Read feature, “The Search for Bigfoot,” for another story about a fantastic creature. Then ask them to compose a short essay comparing the evidence that people found about Bigfoot with the evidence people found about giant squid. What was the same, or different, about these pieces of evidence?
