Beach fans in Oregon have recently been amazed by the dazzling debris of 100 pounds (45 kilograms) of exotic fish after being washed away hundreds of miles from their normal habitat.
A 3.5-foot (1 meter) long lampris guttatus. MoonfishWas found on the shores of Sunset Beach in northern Oregon at 8 am local time on July 14. The colorful creatures had a mixture of silver and bright reddish-orange scales throughout their flat, circular body, with occasional white spots and shimmering golden eyes. ..
After receiving a photo of a beach fish from a passerby, staff at a nearby Seaside Aquarium recovered the remains. Aquarium visitors were later treated to see rare specimens up close and personal.

Tiffany Booth, assistant manager at Seaside Aquarium, said it wasn’t clear what happened to Lampris guttatus, but “it was in good condition and was close to the shore when it died.” Washington post..
Lampris guttatus is a pelagic fish that lives in the open sea, but is common off the coast of California and around Hawaii. National Oceanic and Atmospheric Administration (NOAA).. However, it is very rare to find anything so north. “Usually I don’t think there’s a lampris guttatus of that size off the coast of Oregon,” Heidi Dewar, a NOAA fisheries research biologist who wasn’t involved in the recovery, told Post.
One possible reason is that the rise in seawater temperature is the cause. Climate changeThe lampris guttatus has been forced to leave the overheated water and move to the once cold water. According to NOAA, they are known to travel long distances depending on environmental conditions.
“We see some marine life moving north as seawater temperatures rise,” Dewar said. However, she added that there is not enough data to confirm that the warming sea has driven the fish north.
According to a 2015 NOAA-led study, Lampris guttatus is the only fully warm-blooded fish alive today. Live science previously reported.. Unlike other febrile fish, Lampris guttatus is endothermic and can control body temperature to keep it warm, for example in the deep sea.
Scientists believe that lampris guttatus can exceed 6 feet (1.8 m) and weigh over 600 pounds (272 kg), but little else is known about biology. Seaside aquarium..
Lampris guttatus is not a fisherman’s target, but it is increasingly bycatch in the swordfish fishery, and its abundant meat has become a popular seafood. However, since the population has never been evaluated, there is no way to know if the lampris guttatus population is stable. And, according to NOAA, whether fishing has a serious impact on their numbers. Also, it is unknown how many species of Lampris guttatus actually exist.
The lampris guttatus on the beach in Oregon was frozen by the Seaside Aquarium at the beginning of the next school year when a group of lucky children were given the opportunity to dissect it. After completing this educational exercise, researchers will carry out further analysis of heavy fish.
“Not much is known about these beautiful fish, so whatever we can learn is useful,” Booth said.
