The octopus isn’t just weird-looking — its biology is so bizarre that some scientists have joked it’s not even from Earth.
When researchers sequenced the octopus genome, they found it contains 33,000 protein-coding genes — more than humans — and many of those genes were completely unique, with no known relatives in other animals.
The octopus can:
Change color and texture instantly
Regrow limbs
Solve puzzles
Squeeze through holes the size of a coin
Some researchers even suggested — half-seriously — that octopuses could have come from frozen alien eggs brought to Earth by comets.
It’s not proven, but one thing is clear: the octopus is unlike anything else on the planet.
