![]() Read more about platypus biofluorescence here. a small scorpion glowing green under uv light. Another possibility is that biofluorescence plays no role in the survival of the species, and instead may be a residual trait that is remnant from earlier in the platypus’ evolutionary history. What do platypus, dragonfish and scorpions have in common Theyre all animals that can glow in the dark. While scientists are unsure of its purpose, one suggested purpose of biofluorescence is that it could play a role in camouflage for the small mammals. Platypuses’ dense, waterproof fur absorbs ultraviolet light and emits a blue-green glow, mammalogist Paula Spaeth Anich and colleagues discovered somewhat serendipitously. Although the reasons for biofluorescence are largely unknown, scientists have discovered that sea turtle shells, fungi, and flying squirrels are also sometimes biofluorescent. Initially thought to be unique and rare in the biosphere, discoveries like this one indicate that biofluorescence is relatively common in the animal kingdom. The new discovery expands scientists’ knowledge of biofluorescence, or the phenomenon where organisms absorb and re-emit light. Image: Mammalia 2020 With its venom-laced spurs, idiosyncratic duck bill, and mammalian egg-laying abilities, the platypus was already world. Now, a new study has found that these strange mammals glow blue-green when illuminated by UV-light, adding to their list of odd traits. Platypus under visible (left) and UV (right) light. UV absorption is indicated by dark areas in the far right panel. Cyan to green biofluorescence of 500 nm is seen in the middle panels. These animals have duck-like bills and beaver-like tails and they can only be found in Australia. A male platypus ( Ornithorhynchus anatinus) museum specimen collected from Tasmania, Australia, photographed under visible light and 385-395 nm UV light without and with a yellow camera lens filter. So for your next socially distanced cocktail party, you need to tell your. They are also one of very few mammals that are venomous, as the males have venomous spines on their rear legs. Platypus fur appears brown in visible light, but as the new research shows, their fur glows green or cyan under UV light. Platypuses are one of the planet’s only living members of the monotreme family: the mammalian group of animals which lays eggs. The fur of the platypus absorbs UV (wavelengths of 200-400 nanometers) and re-emits visible light (of 500-600 nanometers), making it fluoresce. Scientists Discover that Platypuses Glow Under a Blacklight But under UV light they appeared green or cyan. ![]()
