After female octopuses have laid their eggs, they sit guard for weeks, months and sometimes as long as a year. At the end of the brooding period, nearly all of the octopus young hatch at once.
When they leave their egg casings, the hatchlings will swim toward the surface and join other small animals in a planktonic stage.
However, baby octopuses are so small, that they can perfectly fit to our finger tip!
Got anything to add?
