![]() Credit: Courtesy of the Natural History Museum of L.A. Green biofluorescence emitted from the Pacific footballfish specimen when exposed to blue fluorescent light. Ludt and Clardy reason that the bioluminescent lure provides the necessary light source for the crystal structures to fluoresce. Upon closer examination, they found small, biofluorescent crystalline structures on the illicium, or the stalk that holds the lure-where there isn’t any bioluminescent bacteria. To their surprise, blue wavelengths of light revealed a green glow on the fish’s lure. But Clardy pumped the brakes-why not examine her in fluorescent light first? The team received the footballfish frozen and thawed her, with plans to inject the precious sample with formalin for preservation. It’s a rare find, with only around 30 other anglerfish specimens in collections worldwide, says Ludt. Only females grow to this size, as most males of anglerfish species are small, and often even latch on to females parasitically. Nicknamed “Spiny Babycakes” on Twitter, the specimen was about a foot long and probably lived between 1,000 and 4,000 feet deep. The new insights stem from Ludt and Clardy’s examination of a female Pacific footballfish that washed up to shore in Newport Beach, California and went viral on social media in May 2021. RARE FIND! Deep sea anglerfish washed up in Newport Beach on Friday morning! On Crystal Cove beach staff were alerted by beach visitor Ben Eslef and were able to retrieve this intact specimen. “Biofluorescence is pretty widespread actually in shallow water marine environments, but the fact that we’re seeing this in the deep sea where there is no ambient light makes this really fascinating,” he adds. “You could think of it as a manipulation-the light comes in one color and then gets emitted in a different color,” says Ludt. While the two qualities can be often confused, bioluminescent organisms produce light, while organisms with biofluorescence are able to change light. County (NHM)īut as the new study demonstrates, the Pacific footballfish ( Himantolophus sagamius) uses an additional trick to create its light shows: Biofluorescence. These anglerfish are naturally this dark color, says Ludt-allowing them to blend into the inky blackness of the deep, dark sea. Living, glowing bacteria called photobacterium light up the anglerfish’s lure to attract unwitting fish. ![]() “Their teeth, like pointed shards of glass, are transparent and their large mouth is capable of sucking up and swallowing prey the size of their own body.The Pacific footballfish specimen. “Only females possess a long stalk on the head with bioluminescent tips used as a lure to entice prey in the darkness of waters as deep as 3,000 feet!” the park wrote. T^he largest females may exceed lengths of 60 centimeters (24 inches) and are globose in shape, whereas males do not exceed 4 centemeters (1.25 inches) as adults and are comparatively fusiform. The Pacific Coast football fish are in the family Himantolophidae, and are globose, deep-sea anglerfishes found in tropical and subtropical waters of the Atlantic, Indian, and the Pacific Ocean. There are 22 species, all in the single genus Himantolophus.Īs it is with most deep-sea anglerfish, sexual dimorphism goes to the extreme. It would have lived at depths of 650 to 2,600 feeta zone where sunlight barely penetrates and food is scarce. Post from Crystal Cove State Park Facebook page Pacific Footballfish are one of the largest species of anglerfishthis specimen is female and about 15.5 inches long and weighs 5.5 pounds. “To see an actual angler fish intact is very rare and it is unknown how or why the fish ended up on the shore,” reads the Facebook post, according to CBS News. The near-black fish with a gaping mouth and razor-sharp teeth lay on the sand on the shore of Crystal Cove State Park’s Marine Protected Area in Laguna Beach last Friday. The park shared images of the fish on social media and identified it as being most likely the Pacific Football Fish. Crystal Cove State Park in California shared tis photo of a Pacific Football fish, a creature from the deep sea that usually is never seen.Ī beachgoer was shocked to discover a rarely-spotted fish, with a monstrous-looking body shaped like a football, washed up at a California beach last week.
