When an enormous marine oddity appeared on a beach in northern Oregon, it sparked curiosity and excitement among the local residents, who eagerly gathered to witness the unusual sight of a rarely-seen fish.
Initially, many believed this creature to be the well-known Mola mola, commonly referred to as the ocean sunfish. However, as images of the strange fish began to circulate, they eventually reached the desk of marine biologist of Marianne Nyegaard. Nyegaard, with her keen expertise, quickly identified the fish not as the familiar Mola mola, but as a different, even more enigmatic species.
The fish in question was the hoodwinker sunfish, or Mola tecta, a species that has only recently been recognized as distinct from the M. mola. In fact, the hoodwinker sunfish was formally identified and described by Nyegaard herself in 2017. Since its identification, there have been only a handful of confirmed sightings, making each new encounter with this elusive fish a noteworthy event.
According to the comprehensive resource Britannica, the hoodwinker sunfish can reach lengths of up to 7.9 feet. This size, while impressive, is still smaller compared to other members of the sunfish family, which can grow to exceed 10 feet in length. The hoodwinker sunfish possesses distinctive features that set it apart, including a streamlined, bullet-link shape, robust skin, and a small mouth equipped with beak-like teeth.
“Originally thought to only occupy the temperate waters of the southern hemisphere, that theory would be challenged as a few have recently washed ashore in California and one as far north as Alaska,” said a statement from the Seaside Aquarium in Oregon. This information highlights the intriguing mystery surrounding the hoodwinker sunfish’s range and distribution, which appears to be more extensive than previously believed.
“This fish, hiding in plain sight, has most likely been seen/washed ashore in the Pacific Northwest before but was mistaken for the more common, Mola mola. Marianne Nyegaard reached out to the Seaside Aquarium to see if they would be willing to take samples for genetics. Staff quickly responded, took more photographs, measurements, and tissue samples.”
The collaboration between Nyegaard and the Seaside Aquarium staff underscores the importance of detailed scientific investigation and documentation to further understand this elusive species.

“Through photographs, Marianne confirmed that it was a hoodwinker and that this may be the largest specimen ever sampled. This fish is still on Gearhart Beach and will probably remain for a few more days, maybe weeks as their tough skin makes it hard for scavengers to puncture. It is a remarkable fish and the aquarium encourages people to go see it for themselves,” the aquarium concluded.
The hoodwinker sunfish, with its mysterious nature and relatively recent discovery, continues to captivate both scientists and the general public. The excitement generated by its appearance on an Oregon beach highlights the continuous discoveries being made in marine biology and the ongoing quest to understand the diverse life forms that inhabit our oceans.
Each new sighting of the hoodwinker sunfish adds valuable data to the scientific community, helping to unravel the secrets of this enigmatic species. The collaboration between local institutions like the Seaside Aquarium and experts like Marianne Nyegaard is crucial in this endeavor, as it combines local knowledge with scientific expertise to advance our understanding of marine biodiversity.
As the fish remains on Gearhart Beach, it serves as a tangible reminder of the ocean’s wonders and the mysteries that still lie beneath its surface. The hoodwinker sunfish’s tough skin, which resists scavengers, allows it to remain relatively intact, offering a unique opportunity for observation and study.
This extraordinary event has not only provided a rare glimpse for a seldom-seen species but also sparked a sense of wonder and curiosity among those who have had the chance to see it up close.
