A beachgoer in the Hawaiian town of Kailua was baffled when a breathtakingly-bizarre sea creature washed ashore.
The remarkable animal was later identified by a local biologist to be an argonaut, which is a type of octopus that lives in the open ocean.
Also called a 'paper nautilus,' the unique creature is rarely seen by swimmers and seems to avoid venturing too close to the shore, making this particular appearance on Lanikai Beach rather noteworthy.
