A 2.15m sea creature that washed ashore in Southern California has been identified as a hoodwinker sunfish, a recently identified rare species thought to live in the Southern Hemisphere.
The University of California, Santa Barbara, said an intern spotted the stranded fish last week at Sands Beach in the university’s Coal Oil Point Natural Reserve.
The intern alerted a conservation specialist at Coal Oil Point, Jessica Nielsen, who initially thought it was a type of local sunfish and posted photos to the reserve’s Facebook page.
That drew the attention of Thomas Turner, an associate professor in UCSB’s ecology, evolution and marine biology department. He examined the fish and posted photos to the iNaturalist online community.
That caught the eye of Marianne Nyegaard of Murdoch University in Australia, who identified the species in 2017 and formally named it Mola tecta but gave it the hoodwinker moniker because it had somehow escaped scientific recognition.
Ms Nyegaard told UCSB in an email that she discussed the images with ichthyologist Ralph Foster of the South Australian Museum but was reluctant to identify the fish as a hoodwinker because the photos didn’t clearly show distinctive features and because it had turned up so far out of its known range.
Ms Nyegaard sent specific instructions to California about what to photograph and tissue samples that should be taken.
Mr Turner and Ms Nielsen were glad to help, but first, they had to find the fish, which had been moved by the tide, according to UCSB.
They walked from opposite ends of the beach and found it several hundred yards from its original position.
Ms Nyegaard said she ended up with a large number of extremely clear photos “and there was just no doubt” about the species.
Sunfish are odd-looking, flat and somewhat oval with fins that resemble little wings.
According to Mr Turner, the fish was just over seven feet long and slightly wider – 2.27m – from fin tip to fin tip. Its dorsal fin was just under 0.75m long. He did not measure the weight.
