“…Unlike snakes (Khvatov et al, 2019), ferrets chose suitable holes from the very first trials of the second test, which indicates that they developed this component of body-awareness in themselves early in ontogeny. It is also curious that when solving similar problems, ferrets, like rats (Khvatov et al, 2016), made fewer mistakes than children (Brownell et al, 2017).…”

"The study of the ability of self-awareness (self-awareness, the ability to perceive one's own body and mental properties separately from objects of the external world) in animals contributes to the study of the specifics of human consciousness. One of the aspects of self-awareness is body-awareness, which is expressed in the ability of an animal to take into account the physical parameters of its body when regulating behavior. We studied the ability of ferrets (Mustela putorius furo) to be aware of the limits of their own bodies. To solve the experimental problem, the animals had to choose holes suitable in size for penetration in the partition that divided the sections of the experimental setup. The shapes and sizes of the holes varied. We have used both small area holes that are suitable for penetration and large areas that are not suitable for penetration. It was found that all 6 animals participating in the experiment were able to choose a hole suitable for penetration from the first trial, despite the fact that it was smaller than the unsuitable one in area. In 18 test trials, ferrets made 105 successful penetrations and 3 unsuccessful attempts. This distribution differs from the uniform one (?2 = 97.25; df = 2; p <0.01). None of the individuals showed a significant reduction or increase in unsuccessful attempts to penetrate the holes This data may indicate that ferrets have knowledge of the boundaries of their bodies and the ability to compare them with the parameters of the penetration hole."

“…On average, children of different ages made 2.5 mistakes while solving these problems. Since 2004 we have been studying body-awareness in various animal speciesincluding rats (Khvatov et al, 2016) and snakes (Khvatov et al, 2019).…”

“…The results of a similar experiment on brown rats (Long-Evans) [58] suggest that these rodents do not need to learn to take into account the natural limits of their bodies: Even naive individuals practically did not make unsuccessful attempts to penetrate into holes of S-type. They formed the skill of taking into account the limits of the body much easier than reptiles, during only 3–4 trials in one series.…”

Snakes Elaphe Radiata May Acquire Awareness of Their Body Limits When Trying to Hide in a Shelter

Body awareness was studied experimentally in the rat snakes Elaphe radiata. The experimental design required that the snakes take into account the limits of their bodies when choosing a suitable hole for penetration into the shelter. The experimental setup consisted of two compartments, a launch chamber and a shelter, separated by a partition with openings of different diameters. The diameters of the holes and/or their position in the partition were changeable. The subjects were 20 snakes divided into two groups, for one of which only the locations of the holes varied; for another, both the location of the holes and the limits of the body varied. The body was increased by feeding the snakes. In the course of the first three experimental series the snakes formed the skill of taking into account the body limits, which manifested in the reduced number of unsuccessful attempts to select holes too small for their bodies. During the fourth series, with the locations of holes randomized for each trial, the snakes demonstrated behavioral flexibility, significantly more often penetrating into the shelter from the first attempt irrespectively of the location of the suitable hole. We argue that these results demonstrate the body-awareness in snakes.
