Wait, that can't happen!
Staff at a marine centre have been left stunned after an octopus thought to be male gave birth.
The lesser octopus, named Roland, has caused a mini sensation at the UK's Hunstanton Sealife Sanctuary.
But staff members are now facing a battle to save Roland's offspring while the mother herself is facing imminent death because she is so devoted.
Apparently the creatures become so focused on looking after their little ones they starve themselves to death.
"Sadly nobody has yet managed to successfully rear octopus fry to maturity," told an aquarium staffer. "But we're going to do our level best and see if we can be the first."
