The curse of being serpentiform: Perceptions of snakelike animals in São Paulo, Brazil
Ethnobiology and Conservation, 2020
Serpentiform body is a morphological adaptation present in several groups of animals. This body shape is often associated with snakes, which can result in the indiscriminate killing of animals. Despite their great socioeconomic and ecological importance, snakes are commonly associated with feelings of aversion, fear, and disgust, that may lead to the inhibition of conservation measures. The present work was conducted in the vicinity of the M'Boi Mirim Park, in São Paulo (Brazil) to record popular knowledge and to discuss public feelings and attitudes towards snakes and other elongated legless animals. We conducted semistructured interviews with 70 participants. The largest percentage of the participants identified snakes by the forked tongue and cylindrical body shape, obvious characteristics to human eyes. In an encounter with a serpentiform animal that may be a venomous snake, this behavior is advantageous as it is better to deal with a false positive than with a false negative. However, this result demonstrated a lack of adequate knowledge about the morphological traits exclusive to snakes. Many participants are afraid of snakes, which, along with misidentification, can cause disastrous encounters and lead to the killing of any snakelike animal. Furthermore, we found that even in a large city, legends and myths about snakes and snakelike animals are passed on through generations. Additionally, people are unaware that some snake populations or even species are under risk of extinction. Our results point to the need for an educational program that changes public attitudes towards snakes and snakelike animals at Municipal parks.
Cross-Cultural Comparison of Student Attitudes toward Snakes
Society & Animals, 2009
Th ere is an increasing amount of research focusing on the origin of the human fear of animals. However, other dimensions of human views of frightening animals have been largely neglected. Th is study investigated attitudes toward snakes. Th e Snake Attitude Questionnaire (SAQ), which consisted of 58 Likert-type items (Cronbach's α = 0.91), was administered in a sample of students from two countries (Turkey and Slovakia). Students showed negative attitudes toward snakes, especially within the Negativistic and Naturalistic dimensions. Turkish students showed more positive Scientistic and Naturalistic attitudes than Slovakian students, and females showed more negative attitudes toward snakes than males. Although biology majors had more positive attitudes, compared with nonbiology majors, knowledge of snakes and beliefs about untrue myths were similar between these two subgroups. Our research indicates that fear of snakes negatively infl uences other attitudinal dimensions (especially naturalistic and scientifi c attitudes) although no students had been injured by a snake. Keeping various pets at home was associated with less fear of snakes. Nature protection actions should combine direct contact with these controversial animals with interventions against belief in untrue myths about snakes.

ABSTRACT. Introduction: Snakes suffer persecution by humans for misperception, misinformation, and fear. In addition, snakes are threatened by habitat decline, which leads them to seek new territories, favoring human-snake encounters. In Costa Rica these threats also exist in the inhabitants of the city, even in those with a high academic level. To favor the conservation of snakes, it is necessary to implement environmental education strategies aimed at a specific target audience. One possible tool is the creation and dissemination of educational videos, which increase knowledge and improve decision-making for their conservation. Objective: Evaluate the effectiveness of an educational video as a tool to change the perception and knowledge about snakes in adults of high educational level in Costa Rica. Methods: We worked with 340 officials from the UNED headquarters, to whom we had applied an initial diagnosis in 2019. We separated the same participants into two groups: 240 officials received an educational video on snakes from the Greater Metropolitan Area (GAM) that we generated for them and 100 officials received a journalistic video as a control group. Finally, we evaluate their responses in a comparative way with respect to the previous diagnosis. Results: After observing the respective video, 75% of the officials maintain their perception of snakes and 68% would act in the same way in case of an encounter. However, 51,5% showed improvement in their general knowledge about snakes, showing dependence on the video observed. Conclusions: The educational video improved the general knowledge about snakes, but the environmental education effort has to face a high percentage of disinterest on the part of the population, which is a challenge for the conservation of snakes.
Schoolchildren and One of the Most Unpopular Animals: Are They Ready to Protect Snakes?
2013
For cultural reasons and due to the narrow vision of environmental policy makers, most conservation efforts focus on a few charismatic species and consequently neglect the majority of others under threat; many unpopular species are even killed in large numbers with little concern. Redressing this bias through educational programs is therefore important. Snakes are unpopular animals; they suffer from human harassment in most places and many populations have declined worldwide. Consequently, they provide suitable substrate to better improve conservation education in schoolchildren. Responses to a questionnaire administered to 2,570 schoolchildren (7-14 years old) from 10 countries showed that many children liked snakes and that most of the students wanted to see snakes protected. Such counterintuitive results were supported by the explanations given by the children, notably the reasons they liked or disliked snakes. Previous physical contact with snakes was often associated with snake likeability. We also found strong and expected differences between countries: for instance, where venomous snakes represented a health risk, most children declared to be afraid of snakes. Overall, our results negate the simplistic, and previously unverified, adult view that snakes are necessarily perceived as frightening animals, thereby justifying their persecution. This study provides an encouraging message, suggesting that it is not compulsory to focus on charismatic animals to convince children to protect wildlife.
A review on human attitudes towards reptiles in Brazil
For many millennia humans and reptiles have interacted, but the attitude of humans towards these animals has depended on culture, environment, and personal experience. At least 719 reptile species are known to occur in Brazil and about 11% of this fauna has been exploited for many different purposes, including bushmeat, leather, ornamental and magic/ religious uses, and as folk medicines. Brazil can therefore serve as an interesting case study for better understanding reptile use by human societies, and the present paper catalogues some of the reptile species being used in Brazil and discusses implications for their conservation. A literature review indicated that 81 reptile species are culturally important in this country, with 47 (58%) species having multiple uses, 54 being used for medicinal purposes, 38 as food, 28 for ornamental or decorative purposes, 20 used in magic/religious practices, 18 as pets, and 40 are commonly killed when they come into contact with humans. Regarding their conservation status, 30 (37.5%) are included on State's Red List, Brazilian Red List or the IUCN Red List. There are many forms of interaction between reptiles and humans in Brazilalthough most of them are quite negative in terms of Environ Monit Assess wildlife conservation-which reinforces the importance of understanding such uses and interactions in the context of protecting reptiles in Brazil. A better understanding of the cultural, social, and traditional roles of these reptiles is fundamental to establishing management plans for their sustainable use.

This paper records the meaning of the term 'offense' and the folk knowledge related to local beliefs and practices of folk medicine that prevent and treat snake bites, as well as the implications for the conservation of snakes in the county of Pedra Branca, Bahia State, Brazil. The data was recorded from September to November 2006 by means of open-ended interviews performed with 74 individuals of both genders, whose ages ranged from 4 to 89 years old. The results show that the local terms biting, stinging and pricking are synonymous and used as equivalent to offending. All these terms mean to attack. A total of 23 types of 'snakes' were recorded, based on their local names. Four of them are Viperidae, which were considered the most dangerous to humans, besides causing more aversion and fear in the population. In general, local people have strong negative behavior towards snakes, killing them whenever possible. Until the antivenom was present and available, the locals used only charms, prayers and homemade remedies to treat or protect themselves and others from snake bites. Nowadays, people do not pay attention to these things because, basically, the antivenom is now easily obtained at regional hospitals. It is understood that the ethnozoological knowledge, customs and popular practices of the Pedra Branca inhabitants result in a valuable cultural resource which should be considered in every discussion regarding public health, sanitation and practices of traditional medicine, as well as in faunistic studies and conservation strategies for local biological diversity.

Background: Venomous snakebite and its effects are a source of fear for people living in southern Nepal. As a result, people have developed a negative attitude towards snakes, which can lead to human-snake conflicts that result in killing of snakes. Attempting to kill snakes increases the risk of snakebite, and actual killing of snakes contributes to loss of biodiversity. Currently, snake populations in southern Nepal are thought to be declining, but more research is needed to evaluate the conservation status of snakes. Therefore, we assessed attitudes, knowledge, and awareness of snakes and snakebite by Chitwan National Park's (CNP) buffer zone (BZ) inhabitants in an effort to better understand challenges to snake conservation and snakebite management. The results of this study have the potential to promote biodiversity conservation and increase human health in southern Nepal and beyond. Methods: We carried out face-to-face interviews of 150 randomly selected CNP BZ inhabitants, adopting a crosssectional mixed research design and structured and semi-structured questionnaires from January-February 2013. Results: Results indicated that 43 % of respondents disliked snakes, 49 % would exterminate all venomous snakes, and 86 % feared snakes. Farmers were the most negative and teachers were the most ambivalent towards snakes. Respondents were generally unable to identify different snake species, and were almost completely unaware of the need of conserve snakes and how to prevent snakebites. Belief in a snake god, and the ability of snakes to absorb poisonous gases from the atmosphere were among many superstitions that appeared to predispose negativity towards snakes of BZ residents. Conclusion: People with predisposed negativity towards snakes were not proponents of snake conservation. Fear, negativity, ambivalence towards, and ignorance about, snakes and the need for snake conservation were strong indicators of the propensity to harm or kill snakes. It seems that if wanton killing of snakes continues, local snake populations will decline, and rare and endangered snake species may even become locally extirpated. Moreover, inappropriate perception and knowledge about snakes and snakebites may put BZ people at increased risk of venomous snakebite. Therefore, intensive, pragmatic educational efforts focused on natural history and ecology of snakes and prevention of snakebite should be undertaken in communities and at schools and universities.
Wild vertebrates and their representation by urban/rural students in a region of northeast Brazil
Journal of Ethnobiology and Ethnomedicine
Background: Recognition of the diversity of living beings, including the classification and naming of species, is a fundamental condition for biological literacy with the aim of developing critical awareness of human relationships with nature, and for which formal education plays an important role. The present study aimed to analyze the representation that urban/rural students have for wild vertebrates and their main sources of knowledge. Methods: Data collection took place in three public schools, one urban and two rural, in the municipality of Campina Grande, Paraíba, Brazil. Questionnaires were given to 990 students (528 urban and 462 rural), distributed among all the grades that comprise middle school (Ensino Fundamental II, grades 6-9) and high school (Ensino Médio, grades 10-12) education. Results: A total of 5877 citations were mentioned by the students, which corresponded to 224 distinct animals with 166 (72.0%) being wild vertebrates, 24 (25.7%) being domestic vertebrates, and 34 (2.3%) being invertebrates. Mammals and reptiles had the greatest observed richness of citations, while mammals (H′ = 3.37), birds (H′ = 2.84), and invertebrates (H′ = 2.94) had the greatest diversity. Positive correlations were found between citations of wild vertebrates and family income (rt = 0.06; P < 0.05) and curricular development (rs = 0.08; P < 0.01); negative correlations were found between curricular development and citations of domestic animals (rs = − 0.22; rs = − 0.11 P < 0. 01) and between age group and citations of invertebrates (r = − 0.14; rs = − 0.11 P < 0.01). As for the sources of knowledge regarding the animals indicated by the students, "media," "daily experiences," "tradition" (here understood as knowledge resulting from interactions with parents and experienced community members), and "formal education" stood out. Conclusions: Comprehension of vertebrate diversity is a fundamental condition for the development of attitudes compatible with its conservation, which emphasizes the importance of biological literacy in achieving this purpose.
Students’ perceptions on snake in Northwestern Bangladesh
2020
Abstract. Jaman MF, Rabbe MF, Alam MM, Shome AR, Hossain MA, Sarker MAR. 2020. Students’ perceptions on snake in Northwestern Bangladesh. Asian J Ethnobiol 21: 62-69. Human-snake interaction has an ancestral history with different outcomes at different times. This study was done to assess the student's perceptions of snakes and current superstitions practiced in some areas of northwestern Bangladesh. We interviewed 348 students from 7 educational institutions under 3 districts from January 2019 to April 2019. We asked dichotomous (yes-no) question to know perceptions about snakes and variation among superstitions of the students. We found significant variation in responses with respect to the demographic status of the respondents. Religion and education were the most influencing factors affecting the results of students’ perceptions. Among the total respondents, 329 (94.5%) had seen snakes, 182 (52.3%) considered snake as a notorious animal, 224 (64.4%) considered snakes as an e...
