"Beached hoodwinker sunfish, which is two metres long, baffles locals on California beach"
"A giant sunfish has washed up on a beach in California, the first time this particular species of the animal has been sighted in the northern hemisphere in 130 years.
The sunfish measuring 2.05 metres (6ft 8 in) and weighing several hundred kilograms, or more than 600lb, was found on the beach of the Coal Oil Point Reserve in California.
Staff at the reserve posted photographs of the enormous fish on social media, incorrectly but understandably identifying it as an ocean sunfish (Mola mola), which is commonly found in seas off the US.
Instead, it was something more remarkable, a hoodwinker sunfish (Mola tecta), a rare species that was first spotted in 2014 by a Danish PhD student working in New Zealand, and formally identified in 2017."
