Heat-sensing drone cameras spy threats to sea turtle nests
Sea turtles lumber from ocean to shore to lay their eggs in the sand. In some places, this effort is protected by humans who patrol beaches on foot, warding off poachers, predators and naïve tourists. But might there be a more effective way? Researchers used thermal infrared sensors mounted on drones to monitor sea turtle […]
The mystery of narwhal behavior, solved by chaos theory
Narwhals are chaotic. At least, that’s what researchers thought until they developed a new math-based method to detect patterns in their seemingly irregular movements. Narwhals (Monodon monoceros) are known as the unicorns of the sea due to their distinctive single tusk, which is actually a feeling, enlarged tooth with up to 10 million nerve endings. […]
In Japanese waters, a newly described anemone lives on the back of a hermit crab

Spectacular new fish species is first to be named by Maldivian scientist
Out in the azure waters and colorful corals of the Maldives, a resplendent, rainbow-hued fish has become the first to be named and described by a Maldivian researcher. New to science, the rose-veiled fairy wrasse (Cirrhilabrus finifenmaa) is named in the local Dhivehi language. Finifenmaa means “rose” and is a tribute to the islands’ pink-hued […]
Afro-Colombian community safeguards pristine oceans with new protected area
An Afro-Colombian community on the southwest coast of Colombia has helped establish a new marine protected area that will create more sustainable fishing and hunting practices while ensuring that one of the country’s most undisturbed ecosystems withstands outside threats of deforestation and pollution long into the future. The Isla Ají marine protected area, which covers […]
Top 15 species discoveries from 2021 (Photos)
With humans sending probes to explore Mars and the sun, one might think we’ve already explored the full extent of our own planet. But scientists say we’ve only begun to find and describe the riches here on Earth. “I think most people believe that we know most species on Earth … but in the best-case […]
