Octopus Eggs Hatching: Like A Sci-Fi Movie

Octopus egg clusters look strange. The mother collects floating eggs and string them together.Octopus eggs form unique looking clusters.The octopus mother builds this structure over a month as she makes individual eggs.

Once the eggs form, the mother begins work on keeping them healthy.Octopus eggs need constant maintenance to stay healthy.The female octopus faces a huge job alone. She defends the eggs against predators and stops parasites from infecting the sacs. She wipes them down with tentacles and blows oxygenated water across the eggs. This keeps the eggs supplied with oxygen; stagnant water causes suffocation.

Octopuses have a depressing reproduction cycle that always ends badly. Octopus mothers refuse to eat.Octopus mothers refuse to eat.They skip easy meals during the weeks and months they watch their brood. Scientists found this while trying to feed a brooding octopus.Octopus mothers try to feed.One octopus is a brooding octopus.

Mothers spend all their energy caring for eggs, often dying just after hatching. Her last act is blowing them into the open water for new lives.

If they can reproduce, watching their eggs is the female octopus's final act. They dedicate themselves to this duty. The process starts with picking a brooding den.a brooding den, a special place where she can lay eggs without threats.

Some octopuses pile rocks at the den entrance to keep out crabs. The den sits in a hidden alcove or cave. The mother octopus usually stays in the den with her eggs for the rest of her life.

Octopus mothers give up more for their young than most other mothers. One species shows motherly devotion to a new level. A research team made a discovery after documenting a single octopus of the speciesGraneledone boreopacifica.They saw theOne octopus has the longest brooding.or gestation period of any animal. Researchers watched the octopus stay in the same spot, caring for her eggs, for four years. She kept the eggs for 53 months until they hatched, but scientists did not see the hatching.

Cold temperatures help mothers survive without food while protecting eggs.Graneledone boreopacifica, such a long brooding period seems nearly impossible. How can any creature survive 53 months without eating even a stray shrimp?

Scientists think her low-energy life kept her strong and extended her survival long enough for her babies to be born. Water temperature also matters. This octopus nested in near-freezing deep-sea water; cold temperatures help keep tissue and extend life.

Octopuses make a huge number of babies. They must. Out of thousands of eggs laid, only about two reach adulthood. This keeps the species healthy, but less than one percent of total eggs hatch. The giant Pacific octopus lays between50,000and100,000octopuses lay eggs in their lifetime.

After the babies hatch, the mother gets a break. While the mother slowly dies, the young octopuses move toward the water's surface. Their new area holdsplanktonand other tiny life forms the octopuses eat until they mature. Lucky octopuses grow big and then go back deep for the rest of their lives.

Octopus gestation and embryonic development involve many hard parts. A successful group sticks together.. Surprisingly, octopus eggs hatch all at once. Perhaps the first few eggs to hatch start the rest. The den fills with thousands of baby octopuses clawing for the surface.. Amazingly, octopus eggs all hatch simultaneously. The first few eggs that hatch might start the rest. The den fills with thousands of baby octopuses clawing toward the surface.

Life is hard for a baby octopus, especially when it is barely bigger than a fingernail. Most baby octopuses are born only a fewbaby octopuses measure millimeters and possess defenses.long, small enough to end up on almost everyone's plate. But they are not helpless.
