Over break I went to Dallas to visit my girlfriend’s family and we started talking about octopuses because her nephew has a recent fascination with them. And as we started talking about octopus I also got curious about them too. I had also just watched Saving Dory on the airplane which had a super cool octopus, a mimic octopus to be exact, as one of the main characters… so I guess octopuses were just on my brain.
I then started doing some research, and yea Octopuses are SUPER WEIRD and so here’s 27 super weird octopus facts.
1) first off, plural of octopus is not octopi, but rather octopuses.
2) when octopuses get bored they eat their arms. The technical term of this behavior is called “autophagy”, and is observed when octopuses are in environments that are not very stimulating.
3) All octopuses are venomous.
4) An octopus can change the color of its entire body in just three-tenths of second.
5) They have no internal or external skeleton, which allows them to squeeze into and out of very tight places about the size of their eyes.
20) The only hard part of their bodies is a sharp parrot like beak located where the arms converge.
6) All octopuses have really short life spans.
7) They can withstand terrible break ups because they have three hearts.
22) When an octopus is swimming the heart that provides the blood to the organs stops beating.
10) Octopuses have 8 arms not tentacles.
8) Due to a copper rich protein called hemocyanin that is used to transport oxygen in octopuses, they have blue blood.
21) The male uses a specialized third right arm, called a hectocotylus as its reproductive organ.
9) Octopus parents die pretty quickly after mating.
11) Each suction cup is equipped with chemoreceptors so the octopus can taste what it’s touching.
12) Each arm usually has up to 240 suction cups with one suction cup being able to hold a weight or force up to 35 lbs
13) 2/3 of the octopuses neurons are in its tentacles. So like basically brain-arms
14) Octopuses are super old! The oldest know fossil of an octopus is 296 millions years ago, which is older than dinosaurs by millions of years.
15) Octopus ink is not just to hide from predators. This defensive chemical is so potent that if the octopus doesn’t escape it’s own ink cloud it can die!
16) Most octopuses for human consumption comes from north and west Africa
17) the country that eats the most octopus is Korea
18) According to the UN food and Agriculture Organization about 270,000 tons or 540,000,000 pounds of octopus are imported by different countries around the world.
19) the word octopus comes from the Greek “oktÓpus” which means “eight foot”
23) the typical octopus is 12-36 inches long and weighs 6-22 pounds. However, the giant pacific octopus typically grows 16 feet and weighs 110 pounds.
24) the largest giant pacific octopus was recorded to be 30 feet long and weigh more than 600 lbs
25) the smallest octopus is the Octopus wolfi. Its smaller than an inch and weighs less than a gram.
26) Octopus are classified as carnivores and eat clams, shrimp, lobster, fish, sharks and even birds!
27) Octopuses are considered to be about as smart as the household cat.
28) After the first-ever full genome sequence of an octopus, biologist claimed octopuses could not be compared to any other animal on the planet. Their genome yields an unprecedented level of complexity with 33,000 protein coding genes more than humans. Their DNA also seems to be highly re-arranged with genetic information leaping around the genome. This actually lead people to believe octopuses are alien however other scientists like Charles Mudese said this
“no matter how crazy an animal's DNA might appear, it is probably from this planet if its cells contain the energy-generating organelles called mitochondria,"
29) When the octopus moves around regardless of the bodies position the eyes remain at the same orientation.
