Octopus

I've always thought octopi were so fascinating. Octopuses are considered the most intelligent of ever single invertebrate. They can solve problems, such as removing a plug or unscrew a lid to get prey from a container, if they needed to. They are the first invertebrates to actually be seen using tools. Tools like using coconut shells to hide from predators looking for them and using rocks and jets of water in a some way that protects them.



Studies show that octopuses learn very easily, they also learn by observing another octopus.
 The octopus has a wide variety of techniques they use to avoid there attackers. Its first defense mechanism of defense is the ability to hide in plain sight. The use off pigment cells and special muscles in its skin, the common octopus can almost match the colors, patterns, and even textures of its surroundings. Predators like eels, dolphins, and sharks swim by without even noticing it at all.

 

 

Some scientists say octopi have different personalities. Every single octopi is venomous, but only the small blue-ringed octopuses are known to be very deadly to humans. There is about 300 species recognizable to humans. Octopuses have three hearts. Really weird I think. Two pump blood through the two gills they have, while the third pumps blood through the body. When seen, an octopus will give off a cloud of black ink to distract its attacker, giving it time to swim away. The ink even has a substance that dulls a predator's sense of smell,  that way the fleeing octopus is harder to track.

The mimic octopuses can change their body shape to mimic some other animals. Octopi have a beaklike jaw that can be a nasty bite, with venomous saliva, mainly used for subduing prey. If an animals rips of a tentacle in a fight and it loses it, it'll grow back with no damage.
