Typically, female octopi lay hundreds, even a great number of, eggs attached to rocks or coral. These spawn hatch into miniature, planktonic juveniles, drifting within the marine environment currents. Beginning, they resemble miniature mature individuals, but undergo several transformations of maturity. Throughout this period, they feed on tiny microscopic creatures. As they grow, they descend to deeper regions and begin to resemble their original form, eventually developing into adult octopuses, ready to repeat the cycle. Regrettably, most octopi perish shortly after birthing, completing a fleeting but remarkable life.
