Octopus Facts: 14 facts about Octopus

like other cephalopods octopus have four

pairs of arms and two eyes and a

bilaterally symmetric Everhard beak I

had a mouth about its center they do not

have a skeleton this allows them to

squeeze into very small and tight

locations they have found in many

diverse oceans in places such as coral

reefs pelagic waters and around the

ocean floor octopus defend themselves

and predators in a number of ways this

includes expulsion of ink using

camouflage dye mattock displays moving

quickly through water and hiding they

can move by crawling or swimming and

when they swim they trail their eight

arms behind them as they do so they are

venomous organisms only one type of

octopus is really deadly to humans now

is the blue-ringed octopus there are

around 300 species of octopus they do

not have a long life expectancy liver is

Lil's 6 months however the larger

species can live up to five years in

specific circumstances the reason they

have such a short life span is that they

die in the reproduction process males

can only live a few months after mating

and females would lie sorely after the

eggs hatch whilst taking care of the

unhatched eggs they do not eat and

eventually die of starvation

octopus have free hearts two of which

pump blood around the gills boss a third

heart is a systemic heart that pumps

blood around the body their blood

contains a copper rich protein that

enables the blood to transport oxygen

we're not supposed to eject ink to give

it a thick black ink in a large cloud

that helps them to escape the coloring

agent that they have is melanin which is

the same chemical that humans have for

their hair and skin color their

camouflage is helped by certain specific

skin cells that change the color opacity

and reflectivity of the epidermis they

can also use their color-changing

ability to communicate and warn other

octopus other species such as the mimic

octopus can also mimic more dangerous

sea snakes eels and lionfish as another

defense mechanism of theirs they

reproduce by using a specialized arm to

transfer packets of sperm from the

terminal organ of the reproductive tract

into the female's mantle cavity in some

species the female octopus can keep the

sperm alive inside her for weeks until

her eggs are mature after they've been

fertilized the female lays up to 200,000

eggs

species of octopus that live on the

ocean floor mainly feed on crabs worms

and other mollusks such as wells and

clams

those species are swimming the open

ocean eat mainly prawns fish another

cephalopods octopus kill their prey by

using a paralyzing saliva before

dismembering it into small pieces with

their beaks

they feed on shelled Mars either by

using force or by drilling a hole in the

shell injecting a secretion into the

hole and then extracting the soft body

of the mollusk large octopuses have also

been known to catch and kill some

species of shark the largest species of

octopus is a Giant Pacific octopus which

weighs in around 15 kilograms and has an

arm span laughter 4.3 meters the largest

specimen of the Giant Pacific octopus

weighed in at 71 kilograms
