A pair of images showing a deep-sea anglerfish small enough to fit in the palm of a hand has captivated social media users, with experts confirming the photos authentically depict the creature’s actual size.<\/p>\n
The images, which began circulating widely in late September 2025, show the same species of anglerfish from two perspectives: one underwater in its natural habitat and another being held in a gloved hand. The viral comparison has garnered tens of thousands of upvotes on Reddit and similar engagement across Instagram and Facebook over recent months.<\/p>\n
Marine biologists have verified that the photos show a black seadevil anglerfish, a rarely-seen deep-sea species encountered during an expedition off the coast of Tenerife in Spain’s Canary Islands. The expedition was conducted by Condrik Tenerife, a Spanish NGO dedicated to shark and ray conservation.<\/p>\n
“These creatures typically live at depths where human encounters are extremely uncommon,” explained Dr. Eliza Cortez, a marine biologist specializing in deep-sea fauna at the Pacific Oceanographic Institute, who was not affiliated with the expedition. “To document one in such detail provides invaluable scientific data and gives the public a glimpse into a world few ever see.”<\/p>\n
The underwater photograph was first shared by expedition member Marc Mart\u00edn on Instagram in February 2025. The complementary image showing the anglerfish in a human hand appeared in a February 11 social media post by Dr. Carlos Cuadrado G\u00f3mez-Serranillos. Additional footage from expedition participant “jara.natura” on TikTok provided further documentation of the same specimen from different angles.<\/p>\n
According to experts at Woods Hole Oceanographic Institution, the black seadevil anglerfish typically grows to approximately six inches in length for females, while males of the species remain remarkably tiny, usually under one inch. The Monterey Bay Aquarium notes that some specimens can reach up to eight inches, though this is still considerably smaller than many people imagine these iconic deep-sea predators to be.<\/p>\n
The diminutive size of the specimen has surprised many viewers who are more familiar with the creature’s outsized reputation in popular culture. Anglerfish have become emblematic of deep-sea mystery, partly due to their distinctive bioluminescent lure\u2014an adapted dorsal spine that dangles in front of their mouths to attract prey in the lightless depths.<\/p>\n
“The specimen in these photos is almost certainly female,” noted marine biologist Dr. Javier Santos from the University of Barcelona’s Department of Marine Ecology. “The presence of the bioluminescent lure is a key identifying feature for female anglerfish. Males lack this adaptation as their sole purpose is reproduction, not hunting.”<\/p>\n
The anglerfish’s unusual reproductive strategy contributes to the significant size disparity between sexes. In many anglerfish species, including the black seadevil, males are essentially parasitic mates that physically attach to females, eventually fusing their tissues and bloodstream with the much larger female. This extreme sexual dimorphism is one of the most pronounced in the animal kingdom.<\/p>\n
While the black seadevil remains small, the Smithsonian Institution points out that the anglerfish family includes over 200 species, with some growing up to four feet long. This diversity highlights the remarkable adaptability of these creatures to the extreme conditions of the deep ocean.<\/p>\n
The viral images have reignited public fascination with deep-sea ecosystems, which remain among the least explored environments on Earth. Marine biologists note that such documentation is increasingly important as these fragile habitats face mounting pressures from climate change, deep-sea mining interests, and other human activities.<\/p>\n
“Each new observation adds to our understanding of these ecosystems,” Dr. Santos added. “These photos not only confirm what we know about anglerfish size but also remind us how much remains to be discovered in the ocean’s depths.”<\/p>\n","protected":false},"excerpt":{"rendered":"
