Rare sea creature makes ripples in California
SANTA BARBARA — A 7-foot (215-centimetre) 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 Jessica Nielsen, a conservation specialist at Coal Oil Point 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 who 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.
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.
Nyegaard sent specific instructions to California about what to photograph and tissue samples that should be taken. Turner and Nielsen were glad to help, but first they had to find the fish, which had been moved by the tide.
They found it several hundred yards from its original position. Nyegaard said she ended up with a large number of extremely clear photos “and there was just no doubt of the ID.” Sunfish are somewhat oval with fins that resemble little wings. The fish was just over 215 centimetres long and slightly wider (227cm) from fin tip to fin tip. Its dorsal fin was just under 2½ feet (75cm) long. He did not measure the weight. —
