Turns out aliens aren’t so sci-fi after all!
“Octopuses: What even ARE they?
They inhabit every ocean at almost all depths and possess a range of features that call to mind sci-fi aliens.
These include prehensile sucker-lined tentacles, highly mobile, camera-like eyes sensitive to polarised light, sophisticated camouflage systems that alter skin colour and patterns, jet-propulsion, three hearts, and the ability to regenerate severed limbs.
The scientists estimate that the two-spot octopus genome contains 2.7 billion base pairs – the chemical units of DNA – with long stretches of repeated sequences.”
