One sea turtle species, the Kemp’s ridley sea turtle (Lepidochelys kempii) has experienced a massive decline in population since the 1940s and efforts are now underway to preserve critical nesting habitat before extinction occurs. Conservation canines have joined these efforts to save the most endangered sea turtle on the planet.
One of the most iconic ground-dwelling birds of the West is the greater sage grouse (Centrocercus urophasianus). Once common across most of the western prairies, sage grouse populations have been steadily decreasing for decades due to habitat loss. Much research has...
Before the European settlement of North America, river otters inhabited every waterway on the continent. The traditional abundance of this mesopredator and the subsequent drastic reduction in population caused by humans makes them an iconic North American species. ...
Built to survive in some of the harshest conditions on Earth, Arctic foxes play an important mesocarnivore role in ecosystems of the far North. Living in lands that remain below freezing for most of the year is a huge challenge for such a small mammal, but these highly adapted and cunning foxes find a way to flourish on the dark, frozen landscape. Their bright white fur may provide their most recognizable trait, but the density and layering of the fur, not the color, is their primary adaptation to battle the brutal cold.
Typically portrayed in popular culture as being ugly, opossums have several physical traits that make them unlike any other North American mammal. First, they are the only marsupial inhabiting the United States and Canada. Their indicative coloration of white heads with pink noses and gray bodies makes them easily identified, however, their most remarkable anatomy is their long, naked, prehensile tail. Although their unusual tail sometimes gets them misidentified as huge rats, opossums are not related to rodents and use their muscular tail to grip branches when climbing trees.
The fisher is one of the most reclusive and therefore misunderstood mammals in North America. Sometimes known as a fisher cat, this large weasel is neither a cat nor does it eat fish, hence both titles are misnomers. The name is believed to have originated by European settlers who called the animal “fitch,” a common name for the European polecat.
