The octopus is a mesmerizing and incredibly intelligent animal, so it’s no surprise these creatures have captivated the imagination of humans for centuries.
These remarkable creatures are related to squids, cuttlefishes, and nautiluses. Almost alien-like in their incredible intelligence and unique appearance, read on to uncover unique features, intriguing behaviors, and more fun facts about the octopus!
1. Intelligent Beyond Expectations!
These incredible animals boast the largest and most developed brains and nervous systems among all invertebrates (animals without a backbone). They are well known for their intelligence, including their ability to use tools!
For example, researchers have observed wild octopuses using shells and other objects as shelters to hide from predators. They will even carry these shelters along with them! Octopuses in aquariums also readily open jars and manipulate other objects to get to food inside.
2. No Birds Here, But You’ll Still Find A Beak!
Did you know that octopuses (and all cephalopods) have beaks? These beaks, which look quite similar to a parrot’s beak, serve as the primary tool for octopuses when consuming crunchy prey such as crabs and clams.
The beak is made of a hard substance known as chitin, which makes it indigestible. This means that researchers can find and identify beaks in a predator’s stomach to research the types of prey that they consume. This is how we know that sperm whales feed on giant squid!
3. A True Master Of Camoflauge.
Octopuses have a remarkable ability to change the color and texture of their skin to blend seamlessly into their surroundings. They use a network of pigment cells called chromatophores in their skin, which change to match the color and pattern of their environment. This camouflage is so effective that even the most astute predators can swim by without noticing their presence.
4. A Brain For Each Arm… And An Extra Heart Or Two!
Octopuses have incredibly unique anatomical features, including three hearts. While one main heart pumps blood throughout their bodies, two smaller hearts are positioned next to their gills to oxygenate their blood.
Additionally, some researchers consider octopuses to have nine brains. Although they possess a central brain for overall control, each of their eight tentacles can act independently, exhibiting its own “mini brain.”
With their unique adaptations and exceptional intelligence, octopuses truly deserve our admiration. From their ability to change color and texture to their remarkable problem-solving skills, these cephalopods continue to amaze and captivate us.
The ocean has so much diversity, each species with their own unique quirks. Stay curious, and learn something new every day. Nature has endless opportunities for that!
