So that's two hoodwinker sunfish discovered in the Northern Hemisphere.

All of the features in the photos matched up with the hoodwinker.

|
The pair looked for physical markers that are common in the hoodwinker sunfish.

She flew down to see it herself, where she spotted her first Hoodwinker Sunfish.

The discovery of the hoodwinker sunfish ( Mola tecta) was announced in 2017 to much fanfare.
|
|
When Nyegaard saw the photos, she knew she had a hoodwinker case on her hands.
|
|
One enjoys tropical waters, another likes the subtropics and the hoodwinker prefers temperate water, Nyegaard told CNN.
|
|
A specimen was collected in 1889 in the Dutch islands but wasn't identified as a hoodwinker sunfish until 203.
|
|
For instance, climate change can see animals deviating from their previous territory - although that doesn't explain the 1889 hoodwinker.

|
Scientists reassessed the fish after the discovery of M. tecta was revealed, and found that it too was a hoodwinker sunfish.
|
|
"Because it had evaded recognition and was misidentified for so long it was named the 'Hoodwinker Sunfish' by its discoverer," he added.

It was Foster who first said this may be a hoodwinker sunfish and not an ocean sunfish in the comments on iNaturalist.
|
|
Where a fish normally has a tail, the hoodwinker only has a clavus -- a structure that looks like a rudder, Nyegaard said.

A large hoodwinker sunfish washed ashore at the Coal Oil Point Reserve in Santa Barbara, California, and scientists were shocked by the discovery.

|
|
Nyegaard said she wants to compare a genetic sample of the hoodwinker found in California with her samples of the fish from Australia and her region.
|
|
Since the two finds are separated by 130 years, it's not outside the realm of possibility that a hoodwinker sunfish just goes astray from time to time.
|
|
It was first spotted by a Coal Oil Point Reserve intern, who thought it might be an ocean sunfish ( Mola mola), which is closely related to the hoodwinker.

Mola tecta compared to Mola alexandrini Mola tecta,, the hoodwinker sunfish, belongs to the family Molidae and genus Mola. It is closely related to the more widely known ocean sunfish (Mola mola). The Latin word "tecta" means hidden. The word "hidden" was adopted for the name because the fish has blended in among other species of sunfish for a long time and has only been discovered recently.

The hoodwinker sunfish is a congener of (in the same genus as) the more widely known ocean sunfish, Mola mola. Mola tecta, like other Mola species, has a flat, almost symmetrical oval shape. It has a smooth body shape, no bump and has a maximum length of 242cm (about 7.9 feet). It does not have spines in its fins nor real caudal fin (tail fin).

In Swedish, Danish and Norwegian it is known as klumpfisk, in Dutch klompvis, in Finnish möhkäkala, all of which meaning "lump fish". The Chinese translation of its academic name is fān chē yú 翻車魚, meaning "toppled wheel fish". The ocean sunfish has various superseded binomial synonyms, and was originally classified in the pufferfish genus, as Tetraodon mola. It is now placed in its own genus, Mola, with three species: Mola mola, Mola tecta (hoodwinker sunfish) and Mola alexandrini.

Full text and maps online It had been commonly assumed that the local Chumash Native Americans used COP seep oil washed up on the beaches to seal their plank canoes and baskets. However, archaeologists assert that the mainland Chumash in fact used asphalt from nearby onshore seeps in beach cliffs. These seeps must be sourced from a similar subsurface reservoir system, but exposure to oxidation is required to make the material hard and useful. In February 2019, a rare hoodwinker sunfish (Mola tecta) washed ashore on Sands Beach in the Coal Oil Point Reserve.

Discovered on a beach near Christchurch, New Zealand, in 2014, the hoodwinker sunfish was the first new species of sunfish to be identified in 130 years. It is thought to live primarily in the Southern Hemisphere and has been found in waters off New Zealand, Australia, South Africa, and Chile. There are, however, two recorded cases of it being found in the Northern Hemisphere: one (previously thought to be a Mola mola) in Ameland in the Netherlands in 1889 and a 7-foot (2.1m) specimen that washed up near Santa Barbara, California in 2019. Mola alexandrini, another Mola species has been found in the Southern Pacific.
