The hamadryas baboon is one of many primate species that has been administered the mirror test.. The mirror test—sometimes called the mark test, mirror self-recognition (MSR) test, red spot technique, or rouge test—is a behavioral technique developed in 1970 by American psychologist Gordon Gallup Jr. to determine whether an animal possesses the ability of visual self-recognition.

Animal reflectors or animal mirrors are important to the survival of many kinds of animal, and, in some cases, have been mimicked by engineers developing photonic crystals. Examples are the scales of silvery fish, and the tapetum lucidum that causes the eyeshine of dogs and cats. All these reflectors work by interference of light in multilayer ...
Common slow worms are semifossorial [2] (burrowing) lizards, spending much of their time hiding underneath objects. The skin of slow worms is smooth with scales that do not overlap one another. Like many other lizards, they autotomize, meaning that they have the ability to shed their tails to escape predators. While the tail regrows, it does ...
Hyraxes are well-furred, rotund animals with short tails. [3] Modern hyraxes are typically between 30 and 70 cm (12 and 28 in) in length and weigh between 2 and 5 kg (4 and 11 lb). They are superficially similar to marmots or over-large pikas but are much more closely related to elephants and sirenians. Hyraxes have a life span of nine to 14 years.
Experts say dogs that regularly run around in circles in pursuit of their own tails could be suffering from OCD. Number 8: Tails were originally used as a balancing aid. Historically, they proved ...
One of the defining features of New Zealand lesser short-tailed bats is their ability to forage both in the air and on the ground. Their ability to forage on the ground is unusual for a bat species. However, New Zealand's early geographic separation around 80 million years ago [19] meant the islands developed free from predators. Without ...
The researchers compared the genomes of six species of apes, including humans, and 15 species of monkeys with tails to pinpoint key differences between the groups. Our ancient animal ancestors had ...
The common dwarf mongoose (Helogale parvula) adopts a tripod stance when being vigilant for predators. [2] In a similar mammal, the thirteen-lined ground squirrel (Spermophilus tridecemlineatus), vigilance behaviour includes four postures: (1) quadrupedal alert (all four feet on the ground with head above the horizontal); (2) semiupright alert (on hind feet with a distinctive slouch); (3 ...
