wolf : any of several large predatory canids (genus Canis) that are active mostly at night, live and hunt in packs, and resemble the related dogs — Webster
gray wolf : a large, broad-headed, wide-muzzled wolf (Canis lupus) that has a dense, heavy coat of usually light brown or brownish gray interspersed with black above and yellowish white below and that was formerly widely distributed throughout North America and Eurasia but is now greatly restricted to the more northerly parts of its range — Webster
Wolf (Canis lupus), also known as the gray wolf, timber wolf, western wolf, and its other subspecies is a canine native to the wilderness and remote areas of Eurasia and North America. It is the largest extant member of its family, with males averaging 43–45 kg (95–99 lb) and females 36–38.5 kg (79–85 lb). Like the red wolf, it is distinguished from other Canis species by its larger size and less pointed features, particularly on the ears and muzzle. Its winter fur is long and bushy and predominantly a mottled gray in color, although nearly pure white, red, and brown to black also occur. — Wikipedia

Spiders have an unfortunate media presence. No number of studies emphasising their ecological value or the potential of their silks to inspire wonder materials can overcome the negative press. The more emotive and sensational the coverage, the more likely it is to travel.
Do raccoons fear coyotes?

A new study in North Carolina caught raccoons on camera foraging with other animals including deer, foxes and flying squirrels and even coyotes. The raccoons' lack of worry about the threat of predation supported researchers' conclusion that raccoons are unlikely prey for coyotes.

Last month, on the centennial of the 19th amendment granting American women the vote, US President Donald Trump announced he would issue a posthumous pardon for Susan B. Anthony. A suffragette, Anthony was convicted of voting illegally as a woman in 1872. The response was mixed. Some applauded the president, others accused him of virtue signaling.

The villain in this drama has a pretty name: Aurora—Latin for dawn. In the world of biochemistry, however, Aurora (more precisely: Aurora-A kinase) stands for a protein that causes extensive damage. It has been known for a long time that Aurora often causes cancer. It triggers the development of leukemias and many pediatric cancers, such as neuroblastomas.
Wolves have been caring for the pack for at least...

Wolves today live and hunt in packs, which helps them take down large prey. But when did this group behavior evolve? An international research team has reported specimens of an ancestral wolf, Canis chihliensis, from the Ice Age of north China (~1.3 million years ago), with debilitating injuries to the jaws and leg. The wolf survived these injuries long enough to heal, supporting the likelihood of food-sharing and family care in this early canine.
