Writing in the journal Current Biology, researchers report that canine brains, like human ones, are sensitive to the acoustic cues of emotion. The findings suggest that these voice areas evolved at least 100 million years ago, in the last common ancestor of humans and canines.
Although wolves and dogs are closely related, they show some striking differences.
Researchers writing in the journal PLOS Computational Biology say that you can tell a lot about the social order of a dog pack by looking at their paths.
A new study has found that today’s dogs are more closely related to each other than they are to wolves – an indication that dogs were domesticated after they diverged from wolves.
Rats will help a stranger in distress only if they have had prior social experience with the type of the unfamiliar individual
Rather than hunting in areas where animals are most abundant, vultures pick out prey by focusing on areas and conditions where animals are most likely to die.
Researchers tracked the eye movements of canines to investigate whether man’s best friend was able to recognize a familiar face from an image. The team wanted to determine if dogs were able to see faces in images and whether they naturally look at familiar and strange faces differently.
Many shark proteins, involved in a number of different functions, match those of humans more closely than they do those of zebrafish, researchers say.
After capturing the first brain images of two alert, unrestrained dogs last year, researchers at Emory University have confirmed their methods and results by replicating them in an experiment involving 13 dogs.
Shunka Warakin is creature from American folklore resembling a wolf, a hyena, or both. It has been suggested by cryptozoologist Loren Coleman that the creature was unknown to modern sources and its name translates to “carries off dogs.” In 1986, Israel Ammon Hutchins shot an animal on a Montana ranch. Coleman suggests that it was an example of the Shunka Warakin. It was stuffed and put on display at Joseph Sherwood’s general store and museum in Henry’s Lake, Idaho. This is the...
The beast of Gevaudan is a man-eating wolf-like animal that resided in the Margeride Mountains of Gevaudan from 1764 to 1767. It was described as having remarkable teeth and long tail. Its fur was tinted white and emitted an unbearable odor. It was said that its victims were killed by the beast ripping at the throat. An estimated 210 attacks were documented; all were men that resulted in 113 deaths and 49 injuries with 98 of the victims partly eaten. Many of the attacks happened while...
The Spearfish remora, Remora brachyptera, is a remora of the family Echeneidae, found circumglobally in tropical and subtropical seas. Its length is up to (50 cm). The spearfish remora is an elongate round-bodied fish, with a large oval suction disc on top of the head. This disc is actually a highly modified first dorsal fin with a raised flattened edge that acts as a seal, and a series of horizontal septae that can be moved so as to create a vacuum in a sealed chamber. Using this device...
The Gharial, Gavialis gangeticus, is one of two surviving members of the family Gavialidae. The Gharial (also known as gavial) is found in small numbers in India and other small populations in the Kaladan and Ayeyarwady River basins in Myanmar. Most gharials are adapted to calmer areas in deep fast moving rivers. They rarely leave the water and do so only to bask in the sun or nest on sandbanks near the river. The gharial is the second-longest of all living crocodilians. A large male can...
The raccoon dog (Nyctereutes procyonoides) is a member of the canidae family (which includes dogs, wolves, and foxes) and is indigenous to East Asia. It is not a true dog, and is the only species in its genus Nyctereutes. It is named for its superficial resemblance to the non-canidae raccoon. The animal carries historical and cultural significance in Japan. Raccoon dogs are native to Japan, southeastern Siberia, and Manchuria. Between 1929 and 1955 they were introduced to the European part...
