Cuttlefish are fascinating creatures, but don’t be fooled by their name—they aren’t fish, and they don’t cuddle! These amazing animals are related to squid and octopus and have some incredible abilities.
One of the coolest things about cuttlefish is their ability to change color. They can do this faster than any other animal, even faster than chameleons! This is because of special cells in their skin called chromatophores. These cells have pigments that can change color when tiny muscles around them contract. This allows cuttlefish to create amazing patterns on their skin for different reasons, like hiding from predators, warning others, or even hypnotizing prey.
In some aquariums, you might see flamboyant cuttlefish. When they’re resting, they blend in with their surroundings, like seagrass or rocks. But when they feel threatened, they flash bright colors to warn others that they might be poisonous.
At first glance, cuttlefish and squid look similar, but there’s a key difference. Cuttlefish have something called a cuttlebone inside their bodies. This is a structure made of calcium carbonate that helps them control their buoyancy. By filling the cuttlebone with water or air, they can sink or float. You might have seen cuttlebones in pet stores, as they are often given to birds like parrots for calcium.
Cuttlefish are excellent swimmers. They use their fins and a special tube called a siphon to move in all directions, making them very agile in the water.
Female cuttlefish lay their eggs on shells or rocks. In some places, people use recycled soda bottles to create safe spaces for these eggs to hatch. This is called a cephalopod recycled bottle nursery. Unlike squids and octopuses, baby cuttlefish, or hatchlings, are born looking like tiny adults. This helps them blend in with their surroundings right from the start, which is important for avoiding predators.
Thanks for learning about cuttlefish with us! Here’s a fun joke to end on: How many tickles does it take to make a cuttlefish laugh? Ten-tickles! If you enjoyed this, keep exploring and stay curious about the amazing world of marine life!
Try creating your own color-changing cuttlefish! Use paper cutouts of cuttlefish and colored pencils or markers. Experiment with different patterns and colors to see how well your cuttlefish can blend into different backgrounds. Discuss why color change is important for cuttlefish.
Imagine you are a flamboyant cuttlefish. Create a short skit with your classmates where you demonstrate how you would react to a predator. Use bright colors and dramatic movements to show how you would warn others of your potential danger.
Create a comparison chart to highlight the differences and similarities between cuttlefish and squid. Include information about their physical features, habitats, and behaviors. Share your chart with the class and discuss what makes each creature unique.
Work in groups to design a recycled bottle nursery for cuttlefish eggs. Use materials like plastic bottles, paper, and tape to create a model. Present your design to the class and explain how it helps protect cuttlefish hatchlings.
Research another marine animal and create a presentation about its unique abilities and adaptations. Compare it to the cuttlefish and share your findings with the class. Discuss how these adaptations help the animal survive in its environment.
Sure! Here’s a sanitized version of the transcript:

[MUSIC][MUSIC] Cuttlefish are not fish at all, and they don’t cuddle like you might expect. However, these tentacled relatives of squid and octopus possess an incredible ability.
I love cuttlefish because of their color-changing skills. Can you tell us more about that? Cuttlefish and other cephalopods have an unmatched ability to change color in the animal kingdom. Unlike chameleons or fish, they can change color almost instantaneously. This is due to tiny cells in their skin called chromatophores, which are responsible for color changes.
Chromatophores are groups of pigment cells controlled by finely tuned muscles. When these muscles contract, darker pigments are revealed, creating amazing patterns for warnings, camouflage, or even to hypnotize their prey.
Over in this tank, we have several flamboyant cuttlefish. When they are resting, they tend to blend in with their surroundings, like seagrass or rocks. However, when stimulated, they can flash bright colors, which is thought to indicate that they are poisonous.
Cuttlefish have one of the most advanced nervous systems among invertebrates.
How can you tell a cuttlefish from a squid? That’s a great question! Cuttlefish and squid look quite similar, but the main difference is that cuttlefish have a cuttlebone, a porous calcium carbonate structure inside their bodies. They use this cuttlebone to control buoyancy, filling it with water to sink or with air to rise. You might have seen cuttlebones at pet stores, as they are often given to parrots for calcium.
Using their fins and siphon, cuttlefish are incredibly maneuverable, allowing them to move in various directions.
It’s great that you’ve decided to clean up some litter from Monterey Bay. What are we looking at with all these bottles? The female cuttlefish lays her eggs on shells or rocks, and we can place them in these incubation chambers made from recycled soda bottles.
Yes, a cephalopod recycled bottle nursery! Unlike squids and octopuses, cuttlefish have no immature developmental stage; they are born as miniature versions of adults, allowing them to camouflage even as tiny hatchlings.
Here we have a tank full of small cuttlefish hatchlings. At this size, they are very vulnerable to predators, so camouflage is crucial for their survival. Let me move some of the rocks around to see how many are in here.
Thanks for showing me around this cuttlefish exhibit! Do you have any final words of wisdom?
How many tickles does it take to make a cuttlefish laugh?
How many?
It takes TEN tickles.
I think we’re done here. If you enjoyed learning about cuttlefish, check out the rest of our playlist from Monterey Bay. We have many more great videos coming your way. Stay curious!

Cuttlefish – A marine animal related to squids and octopuses, known for its ability to change color and texture. – The cuttlefish used its color-changing ability to blend in with the coral reef.
Color – The property of an object that is produced by the way it reflects or emits light, often used by animals for camouflage or communication. – The bright color of the poison dart frog warns predators to stay away.
Change – To make or become different, often used to describe how animals adapt to their environment. – Chameleons can change their skin color to match their surroundings.
Chromatophores – Special cells in the skin of some animals that contain pigments and can expand or contract to change the animal’s color. – The chromatophores in the octopus’s skin allowed it to hide from predators.
Pigments – Natural substances that give color to animal and plant tissues. – The pigments in the butterfly’s wings create beautiful patterns that attract mates.
Flamboyant – Having a strikingly bold or brilliant appearance, often used to describe animals with bright colors. – The peacock’s flamboyant feathers are used to attract a mate.
Cuttlebone – A hard, internal structure found in cuttlefish that helps them control their buoyancy in water. – The cuttlefish adjusts the gas in its cuttlebone to float at different depths.
Buoyancy – The ability of an object to float in water or air. – Fish use their swim bladders to control their buoyancy and stay at the right depth.
Hatchlings – Young animals that have recently emerged from their eggs. – The sea turtle hatchlings made their way to the ocean after emerging from their nests.
Predators – Animals that hunt and eat other animals for food. – Lions are predators that often hunt in groups to catch their prey.
