RESUMO:

Coloring is responsible in organisms for mediating the relationship between the individual and the environment in which they are inserted in important ways, including social signaling, anti-predation defense, parasitism, thermoregulation, protection against sunlight at wavelengths light in the range of ultraviolet, microbes and abrasion. To this end, several factors are associated with the production of colors in animals and, in addition, many factors are also associated with the perception of coloration expressed in the body of animals. Many factors can influence the way colors are expressed, either individually, such as parasitism, or evolutionarily, as pre-dation pressures. Thus, this paper aims to physically describe the coloration expressed on the coat of Artibeus planirostris and to know if parasite infection and predation pressure visually influence how this coloration is expressed. For this, the Artibeus planirostris stains were meas-ured in six body parts of different individuals, aiming to use the color obtained to visually model the way individuals at different times in the life history of the species see each other and com-pare how they were seen by the predator and the conspecific. In addition, the influence of par-asite infestation was tested to determine if there was a change in the expression of coat color. Our results showed that the Artibeus planirostris coat was visually perceived better by the owl than by the conspecific and that different aspects of the species biology are distinguished by the conspecific. We also show that parasite infestation influences the coloration expressed on the animals' coat, and is also distinguished by other individuals between parasitized and non-para-sitized animals. Our work is pioneering in information about the coloration of bats and espe-cially about how these animals see themselves and what are the relationships between this pa-rameter and interactions with predators, as well as the influence of parasitosis on coloration expressed in the coat of animals. This shows us how vast this area can be for studying the group's behavior and sensory ecology, opening up a huge range of opportunities for other re-searchers.
