There is a broad set of human beliefs, attitudes and behaviours around the issue of magical animals, referring to both mythical animals not recognized by science and extant animals that are recognized by science but have magical properties. This is a broad issue ranging from spiritual beliefs around mythical animals living in Malagasy forests, to cultural heritage associated with the Loch Ness Monster in Scotland. Beliefs and behaviours around magical animals can have positive and negative impacts on biodiversity conservation goals. Yet, so far, the discipline of conservation biology has not adequately considered magical animals, neglecting to account for the broader knowledge from outside the natural sciences on this issue, and taking a narrow, utilitarian approach to how magical animals should be managed, without necessarily considering the broader impacts on conservation goals or ethics. Here we explore how magical animals can influence conservation goals, how conservation biology and practice has thought about magical animals, and some of the limitations of current approaches, particularly the failure to consider magical animals as part of wider systems of belief and culture. We argue that magical animals and their implications for conservation merit wider consideration.Keywords Conservation, ethics, Madagascar, magic, snakes, spirituality, Tanzania Introduction I n a proposed new highway in Iceland was contested in court on the basis that it would cross the habitat of a valued species (The Guardian, ). In , , tourists visited a site in Scotland primarily because it is inhabited by a rare, endemic animal (ASVA, ), supporting a thriving ecotourism industry. Hyaenas Crocuta crocuta in Ethiopia are tolerated because they provide vital provisioning ecosystem services that benefit local communities (Baynes-Rock, ). In Madagascar, in contrast, some snakes are persecuted because they provide ecosystem disservices, harmful to human health (Tingle, ). These are seemingly straightforward conservation stories, where human-animal interactions produce benefits and costs for both biodiversity and people. Yet there is an often-overlooked complexity to these cases, with important implications for conservation outcomes. The species involved are either not recognized by science, or the properties of these species that local people resent or value are not recognized by science. The Icelandic protesters were protecting the habitat of Huldufólk, or elves. Ecotourists in Scotland were seeking the Loch Ness Monster Nessiteras rhombopteryx. The Ethiopian hyaenas provide the ecosystem service of eating evil spirits. The Malagasy snakes harm humans and cattle by transforming into sharp spear-like forms and dropping from trees. We argue that conservationists should take magical animals seriously, because they have important positive and negative implications for many species and habitats. Magical animals have been neglected and oversimplified within conservation, probably because of a lack of tr...
