The suckers we see on the arms of an octopus look like the suction cups we use to attach things to windows, but they are far more complex. The octopus is a very intelligent animal, with many interesting design features.
Everyone knows that an octopus has eight arms. That’s what the name “octopus” means. It may not be as well known that they have no skeleton. The only hard part of its body is a beak similar to the beak of a parrot. The lack of a skeleton allows the octopus to slip through extremely tight places.
Octopuses can squirt ink into the water to avoid predators, and they can get away using jet propulsion by expelling water. They can camouflage themselves or change to bright colors to distract or frighten an enemy. Octopuses have venom which they can use defensively or to capture food.
Octopuses have blue blood because it’s copper-based rather than iron-based like most animals. Octopuses have three hearts—one for pumping blood through the body and two for pumping blood through the gills to supply oxygen. Even though they have brains, their highly complex nervous system is centered mostly in their arms. The arms can do some things on their own without input from the brain. The sucker of an octopus can taste what it’s touching to see if it’s edible. The arms can pass things from one to another without interaction with the brain. The suckers never get stuck together because they can sense octopus skin. Amazingly, some octopuses can even detach an arm to escape a predator. The severed arm will continue to move and distract the predator while the octopus escapes.
Octopuses are capable of learning, and they exhibit short-term and long-term memory. As we discover more about them, we realize they are intelligent animals with very complex bodies that give evidence of a Designer.
