Octopus Biology Explained

Описание: October 8 is World Octopus Day. 🐙 Octopuses have three hearts, blue blood, nine brains, and sixty percent of their neurons in their arms rather than their central brain — meaning each arm can act independently. They solve puzzles, open jars, navigate mazes, and recognize individual human faces, all within a lifespan of one to two years. The octopus has no skeleton, fits through any opening its beak can pass, and changes color through chromatophores in under a second.
