Tag archives for freshwater species of the week
Posted by Dr. Solomon David, research associate at Shedd Aquarium. Gars and bowfin have been around since the dinosaurs; in fact, they’ve outlasted them. More recently, however, a modern creature has threatened these ancient fishes: humans. Misunderstood and much-maligned, these fishes were targets of eradication efforts for more than a century (1). Now, perceptions of these…
Recent decades have not been kind to amphibian populations throughout the world. As amphibian declines and extinctions keep escalating at an unprecedented rate, it comes as a breath of fresh air when something is discovered that was feared to be lost forever.
By Giulio Boccaletti, Global Managing Director for Water at The Nature Conservancy and Maria Damanaki, Global Managing Director for Oceans at The Nature Conservancy One day in 2014 a female eel set off from Nova Scotia on a long and hazardous journey to her spawning grounds. This was no ordinary eel. Scientists had released her with…
I’ve found my way to the end of the world, or more precisely Ushuaia on the southern tip of Tierra del Fuego. I’m most interested in seeing some of its most recent immigrants, the Canadian beavers (Castor canadensis).
Since the 17th century, 80% of the Dalmatian Pelican’s breeding sites have disappeared, but efforts in Montenegro’s Lake Skadar aim to protect and stabilize its population.
Barbecues and clambakes. Ice cream and berry pies. Summer is the season of food, food and more food. Is there a way to binge and still stay healthy? For answers, look far underground, say scientists, to the denizens of darkness: blind cavefish. Biologists studied blind cavefish, Astyanax mexicanus, living in freshwater pools in deep caves…
A poison dart frog from Peru that mimics its neighbors in incredible detail is evolving into a new species, scientists believe.
A new species of bright-orange, fingernail-size frog found in a Panama rain forest is unlike any of its relatives, scientists say.
Archerfish, which use water jets to take down prey, are much more skilled and sophisticated target shooters than thought, a new study says.
Seventeen Critically Endangered juvenile Siamese crocodiles have been released into into a protected wetland in Laos, the Wildlife Conservation Society (WCS) announced today. The Siamese crocodile is named Freshwater Species of the Week for its critical role in the fragile Xe Champhone and other wetlands in Southeast Asia. Saving the species from the brink of extinction in the wild and restoring its habitat will help ensure a healthy environment and create socio-economic opportunities for the people who depend on the wetlands.
How long can alligators live out of the water? Are there more animals out there that can re-grow body parts? Read this week’s Ask Your Weird Animal Questions.
Freshwater Species of the Week: Fishing Spider
When the Wisconsin Department of Natural Resources posted on its Facebook page that giant fishing spiders had been spotted around the state the news was shared more than 10,000 times. More than 2,000 comments were received, including from people posting their own images of the arachnids. Many posters expressed concern and abhorrence. But these are amazing animals with super powers, able to walk or sail with the wind on water, and they can haul up aquatic animals five times their weight.
Electricity is a way of life for many animals, turning hornets into little generators and the enlarged chins on fish into navigation tools.
A surprising study reveals ants can walk on water—find out what other animals can also accomplish this incredible feat.
As an Indiana Hoosier, I was thrilled to learn of this new species: the Hoosier cavefish (Amblyopsis hoosieri). Described this week, the Hoosier is the first species of cavefish to be named in the U.S. in 40 years, making its entry into the pantheon of known creatures even sweeter. The small, blind fish can grow…
