The mimic octopus is a truly amazing sea creature! It's famous for its incredible ability to copy the look and actions of other animals. This special skill helps it survive in the ocean.
This octopus is not very big. It grows to about 60 centimeters (2 feet) long, including its arms. That's roughly the length of a school ruler. It has small "horns" that stick out above each eye.
Its natural color is light brown or beige. But when it wants to scare off danger, it changes! It often turns a striking white and brown striped pattern. This helps it pretend to be poisonous or mean sea creatures. Its amazing ability to change shape is why it's called the "mimic" octopus.

Where the Mimic Octopus Lives
The mimic octopus lives in the Indo-Pacific region. This area stretches from the Red Sea in the west to New Caledonia in the east. It goes from the Gulf of Thailand and the Philippines in the north to the Great Barrier Reef in the south. Most of the times it has been seen are in Indonesia.
It mostly lives in sandy or silty areas. It prefers depths of less than 15 meters (49 feet). It likes murky and muddy seafloors. This helps it blend in with its natural brown-beige color.
Unlike many other octopuses, the mimic octopus likes to live in river mouths and estuaries. These are places where rivers meet the sea. Other octopuses often prefer reefs for shelter. But because the mimic octopus can pretend to be dangerous animals, it's safer in open areas.
What the Mimic Octopus Eats
The mimic octopus can be called both a hunter and a forager. It's a hunter because scientists have seen it stalk and catch small fish. But more often, it forages for food.
It uses a jet of water from its siphon to glide over the sand. It also uses its long, thin arms to reach into cracks in coral and holes in the sand. Then, it uses its suction cups to grab small crustaceans and eat them.
Since the mimic octopus prefers shallow, murky waters, its diet mostly includes small fish and crustaceans. These are the most common animals it can find and eat in those conditions. Mimic octopuses are carnivores, meaning they eat meat. They are not known to eat any plants.
The mimic octopus is different from another famous octopus called the Wunderpus photogenicus. The Wunderpus has white markings that don't change.
Behavior
The mimic octopus moves by shooting water through a special tube called a funnel. This helps it glide over the sand. It's usually looking for food like small fish, crabs, and worms.
This octopus is very clever. It uses its mimicking skills to hunt too! For example, it might pretend to be a crab. When another crab comes looking for a mate, the octopus quickly catches it for dinner.
Mimicry is a common way for animals to survive. Some flies, for instance, have yellow and black stripes like bees. This makes predators think twice before attacking. But the mimic octopus is special. It's the first known animal that can copy more than one other species. It's also the first octopus known to have this amazing ability.
Scientists have seen the mimic octopus copy up to 18 different marine animals. The octopus can choose which animal to mimic based on the danger it faces:
- Lionfish: These fish are venomous and have brown and white stripes. They also have long, spiny fins. The octopus changes its color and shapes its eight arms to look like these spines. This makes predators think it's a dangerous lionfish to avoid.
- Sea Snake: The octopus can wave two of its arms in opposite directions. It also shows yellow and black markings. This makes it look just like a venomous sea snake.
- Flatfish: To mimic a flatfish, the octopus pulls its arms together on one side. Then it flattens its body and moves along the ocean floor. This makes it look like a harmless flatfish swimming by.
- Jellyfish: Sometimes, the mimic octopus will puff up its head and siphon. It lets its arms trail behind it. Then, it swims to the surface and slowly sinks, spreading its arms out. Many animals that hunt octopuses avoid jellyfish, so this trick works well!
Adaptations
The mimic octopus faces the constant threat of predators in the ocean. But it's not helpless! It uses a combination of amazing strategies to protect itself:
- Master of Mimicry: Its most famous trick to scare or confuse predators.
- Expert Camouflage: Blending in perfectly with its muddy, sandy habitat.
- Intelligent Choices: Using its big brain to decide which disguise is best for each situation.
- Habitat Preference: Choosing murky waters where it's naturally harder to spot.
The mimic octopus is a true marvel of evolution, showing us just how clever and adaptable life in the ocean can be!
Interesting Facts about the Mimic Octopus
- Scientists first found this octopus in 1998 near Sulawesi, Indonesia.
- These creatures have about 300 million neurons in their main brain, and each of their eight arms even has its own mini-brain with about 50 million neurons! This gives them amazing control, a great sense of touch, and excellent decision-making abilities.
- The mimic octopus has incredible control over its skin. They don't just change color; they can also change the texture of their skin to become bumpy or smooth, helping them blend in even better.
- While its natural color is light brown/beige, it often changes to a more noticeable pattern of striped white and brown. This bold pattern is often used when it's mimicking poisonous species, sending a clear warning to potential predators.
