Not to freak you out or anything, but scientists have just revealed that octopuses are so weird they’re basically aliens.

The first full genome sequence shows of that octopuses (NOT octopi) are totally different from all other animals – and their genome shows a striking level of complexity with 33,000 protein-coding genes identified, more than in a human.

There we were thinking it was quite freaky enough when they learned how to open jam jars.

US researcher Dr Clifton Ragsdale, from the University of Chicago, said: ;The octopus appears to be utterly different from all other animals, even other molluscs, with its eight prehensile arms, its large brain and its clever problem-solving abilities.

‘The late British zoologist Martin Wells said the octopus is an alien. In this sense, then, our paper describes the first sequenced genome from an alien.’

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.

How many other non-mammal maritime species had their genome sequenced?
It sounds like this conclusion comes from a lack of overall view.
