Bizarre sea creature a rare sight on Hawaiian beach; video

A month after a massive invasion of box jellyfish, a Kailua beach was the site of another unusual sighting, this one a bizarre sea creature that had many people scratching their heads in bewilderment, according to KHON.

Tiphareth Aquarian spotted the sea creature along the shoreline of Lanikai Beach on Oahu, Hawaii, and snapped a photo of it and took some intriguing video of it pulsating while sitting in the sand. KHON has the story:

In an attempt to identify the sea creature, KHON contacted Megan Porter, an assistant professor of biology at the University of Hawaii at Manoa. She had no difficulty in ascertaining what Aquarian had discovered.

It was an argonaut, a type of pelagic octopus typically found in the open ocean. It's also known as a paper nautilus.

"What the picture shows is a shell that the females in this particular group of octopus makes themselves as a protection for their eggs," Porter told KHON. "So it's an egg case that they carry around with them to protect their eggs while they're developing.

"I don't think that they come in close to shore very often, or they're out at times when people aren't out in the water, so to have one wash up on shore where people can actually see it, it's actually quite rare.”

Perhaps it was drawn in by the lights or got caught in a wave, Porter surmised.

It was said to have returned to the ocean soon after Aquarian spotted it.
