Many amphibians — possibly all of them — are biofluorescent, according to a new survey.
Amphibians are half-landlubbers, half water-babies. They breathe through skin that is moist, warty, crested and in some cases, poisonous or hallucinogenic. Some wear dull, leaflike-camo patterns. Others sport Guy Fieri flames.
And as cute, gross, pretty, ugly, magical and witchy-named as these slip-sliding creatures may be, they’ve been hiding something in a secret, fluorescent world invisible to humans. Many amphibians, whether salamanders, frogs or their distant cousins — possibly all of them — glow, according to a survey published Thursday in Scientific Reports.
“There is still a lot out there that we don’t know,” said Jennifer Lamb, a biologist who conducted the research with Matt Davis, both at St. Cloud State University in Minnesota. “This opens up this whole window into the possibility that organisms that can see fluorescence — their world may look a lot different from ours.”
The study paves the way for new research into how or why amphibians possess this special adaptation, which has potential applications in medical technology and conservation. Continue reading
