How octopuses reproduce:

The breeding time of octopuses in the ocean is generally concentrated in spring and autumn, and the sea water temperature in spring and autumn is about 16. Octopuses like to spawn in snail shells, so they can be used to sink to the bottom of the sea with ropes through red snail shells, and extract and catch them on time. In autumn and winter, they often burrow in the mud and sand of the deep sea.

Octopuses are dioecious. The male has a specialized wrist, called the stem carpus or handover carpus, which is used to place the sperm bag directly into the mantle cavity of the female. During the breeding season, female octopuses lay eggs, about centimeters long, with a total of more than 100,000, under rocks or in holes.

During incubation, the female guards the eggs, cleans them with a suction cup, and agitates the eggs with water.

Female octopuses need their larvae to hatch after 4 to 8 weeks after a single spawning. Juvenile octopuses are small and adult-like, and after hatching, they drift with plankton for several weeks before sinking to the bottom to hide.
