Octopus anatomy is quite alien, including eight arms plus nine brains, three hearts and blue blood

Two branchial hearts pump blood to the octopus's gills, while the third systemic heart pumps blood to the rest of its body

Octopuses have copper-based hemocyanin in their blood, which gives it a blue colour and helps transport oxygen more efficiently in cold, low-oxygen environments

This adaptation enables them to thrive in deep-sea habitats where oxygen levels are limited

Octopuses have a large central brain and eight smaller "mini-brains" called ganglia, which can function independently to control different parts of their body

Additionally, they have eight arms, covered with suckers that taste and feel, helping them crawl, swim, and manipulate objects

They're able to change their color and texture to camouflage themselves in the blink of an eye, thanks to a complex system of specialized pigment sacs called chromatophores

However, octopuses have incredibly short lifespans, and typically live between one to five years in the wild
