Understand the Life Cycle of the Octopus

The video explores the life cycle of octopuses, focusing on their reproduction, growth, and survival. Female octopuses lay thousands of eggs, but only 1% survive to adulthood. The mother octopus protects her eggs until she dies from exhaustion. Octopuses go through larva, juvenile, and adult stages. They are part of the ocean's food chain, with many larvae becoming plankton. Octopuses grow rapidly, with some species reaching significant sizes. They are solitary hunters, using stealth and regeneration to survive. The video concludes with a review and quiz on the octopus life cycle.
