How Many Babies Do Octopus Have Octpi Variatoin
E'er wonder how baby octopuses come up into this world? Who takes care of them? How many eggs does a mama octopus lay? Why does she die after her young hatch? You lot're nigh to observe out every bit we dive into how octopuses give birth and treat their precious eggs!
There are many different species of octopus, and how they give nativity varies depending on the species. Some lay eggs in a den nether rocks or coral reefs where they'll be safe from predators like sharks and stingrays until their young hatch (virtually vi months later). Near cephalopods volition not eat 1 another as adults, but the younger ones are vulnerable to predators.
In order to protect their young, mama octopuses scour their surroundings for a safe space to start her ultimate sacrifice: laying her eggs!
Finding A Home For Her Baby Eggs
Allow's starting time post-mating when a female octopus begins to look for her ideal den.
Once called, the mother octopus will frequently elevate rocks to fortify her den to be sure her babies will be protected from predators.
Afterward when her space is set up, she volition plow upside downwardly and cling to the roof of her den to brainstorm laying her eggs in a protected spot.
How Many Eggs Does An Octopus Lay?
Some octopuses lay hundreds of thousands of eggs at a time, while others will just produce ane egg sheathing at a time. They tin comprise up to 100 embryos!
Each egg is created in the ovary and and then coated with a nutrient-rich yolk for it to develop in – the translucent, rubbery white sac that is visible to u.s.!
Mama octopus will expel each egg, one by i out of her funnel (or siphon). So, using suckers near her neb, she painstakingly braids the eggs together into long chains of eggs called festoons (is it just me, or is that a fun word to say out loud?).
When they reach a certain length (effectually 175 eggs), she volition produce an adhesive-like secretion sticking the end of the chain to the top of her den. She volition then begin another strand correct abroad or descend to residual and protect her brood, depositing 70,000+ fertilized eggs and braiding around 400 strands (festoons) of eggs.
This takes effectually 30-40 days!
Once all eggs are hanging similar a '70s beaded concatenation curtain, mothers meticulously make clean and waft currents of water over their eggs so they get a constant supply of fresh, oxygenated water.
How Long Does It Take For An Octopus Egg To Hatch?
This is a not bad question! How long it takes for eggs to hatch is highly dependent on octopus species and h2o temperature.
For instance, the incubation flow for the Behemothic Pacific Octopus (Enteroctopus dofleini) living in common cold water is around 6-7 months compared to the Common Octopus (Octopus vulgaris) living in warm h2o whose immature octopuses hatch out subsequently a brusk 50 days.
🐙 Fun Fact 🐙
Unfortunately, once the babies pop out and first their tiny lives in an ocean filled with big and hungry creatures, the chances of an octopus making information technology all the manner to machismo are just effectually ane%.
Acquire How Dissimilar Female Octopus Species Care For Their Eggs!
The whole egg-laying and caring process can become really wacky when nosotros have a expect at some of our abyssal octopus friends!
Abyssal Octopus
The dedicated Abyssal Octopus (Graneledone boreopacifica) cares for her eggs for 53 MONTHS!
Yep, you did the math right…that's over Four YEARS! Way to put all the other octo moms to shame Graneledone boreopacifica.
She tin practise this considering temperatures are near freezing 37०F (3०C), i,400 meters (four,600 feet) below the surface where she broods her eggs. This keeps her metabolism extremely slow while assuasive her to protect her eggs for such an extended amount of time. She doesn't eat the entire fourth dimension and hardly moves.
I don't know about you lot, but I can barely become from breakfast to tiffin without a mid-morning snack!
Putting in this kind of time to intendance for her eggs does take some benefits. It allows her young to grow bigger, which gives them a greater risk of survival once they hatch.
Deep-sea Octopuses
Shallow-water octopus species ordinarily follow the typical pattern of the female person laying her eggs in her den, watching over them until they hatch. They then succumb to starvation and death. This is where deep-sea octopuses differ- they are all about breaking that octopus maternity mold.
The Dumbo Octopus (Grimpoteuthis sp.) and Vampire Squid (Vampyroteuthis infernalis) can go pregnant WHILE being significant. Since finding mates in the deep blue sea isn't always easy, these two female person octopuses hold onto sperm in their mantle and only use it to fertilize their eggs when they come across an acceptable piece of coral or stone that they can attach them to.
The Female person Coating Octopus (Tremoctopus violaceus) makes a calcium carbonate stick to behave her babies on while she drifts through the open seas. Some other deep-sea out-of-stater is the Glass Octopus who broods all the eggs inside of her mantle (torso) where they hatch direct from her!
A New Beginning For Infant Octopus Means The Finish For Mama Octopus
Octopus are semelparous, which ways they only reproduce once. This comes at the terminate of their relatively short lifespan that on average lasts 3-5 years but can be as short as six months.
Once a female octopus settles down to treat her eggs, she stops eating. Having exhausted all her energy making sure her babies are well cared for until they hatch, the octopus mother dies. This procedure is called senescence.
Simply, Why Do They Stop Eating When They Take Babies?
This puzzled scientists until they uncovered that an octopus's optic gland, which is located betwixt their eyes, is part of the senescence process. The optic gland is similar to our pituitary gland; A small-scale bean-shaped organ at the base of our encephalon that tells other glands, which hormones to release and helps regulate growth, blood force per unit area, and reproduction.
Basically, all of our man urges, along with octopuses, are controlled past a pea-sized organ. A chemical secretion from the female octopus's optic gland stops her want to consume during the reproductive procedure leading to her ultimate demise.
Octopus are substantially pre-programmed to dice.
While this may seem sorry when viewed through our human lens, an octopus has completed the job which it was meant for: having offspring and passing along their genes. Mission achieved!
Why stick around afterwards the most important function of their life has been accomplished?
🐙 Fun Fact 🐙
Female octopuses too have cannibalistic tendencies, which scientists have hypothesized could result in them eating their ain hatchlings if their hunger wasn't existence suppressed.
And then, Where's Octo Dad?
If you lot're thinking octopus dads fare any better, they don't. Later mating, if a male person octopus isn't quick enough, they are eaten past their mate!
Once the female person has what she needs, the male simply becomes a big juicy steak in her eyes. To be off-white, the female octopus could probably utilize a poly peptide heave to help fuel her egg-laying and brooding futurity. Even if the male person does manage to escape, they also die shortly after, thanks to their optic gland.
Mama Octopus Giving Birth: The Ultimate Sacrifice
And so… how do octopus give birth? It's quite simple- They completely sacrifice themselves.
And, while an octopus mom will never be able to see her babies grow up, she gives up everything, including her life, to make certain they are well cared for until they hatch. For these devoted moms, the miracle of life sure is bittersweet.
