Mermaids do exist – in California.

A woman with webbed toes identified herself as a mermaid named Joanna after she was found mostly naked and walking along a dark road in the middle of the night in Fresno County.

The young brunette was wearing only a black sports bra and had wet hair when cops found her near Millterton Road and Brighton Crest Drive in Friant around 3:15 a.m. Tuesday, the Fresno Bee reported.

She told cops she was a mermaid who’d just been in the water. But she answered “I don’t know” to most of their questions.

“She was wet. She said she had been in the lake, said she needed help and needed to be taken to the hospital,” Fresno Police Lt. Mark Hudson told YourCentralValley.com. “We did go through records after fingerprinting her and we still did not come up with her identity.”

The mystery woman is 5-foot-4 and weighs 150 pounds. She has webbed toes on both feet. Officials said she could be between 16 and 30 years old and either white or Hispanic.

“There are some strange things that happen up here,” said neighbor Karon Renwick. “We’re in the mountains.”
