“…Nevertheless, the reduction of the species is associated with vehicular accidents, fire, habitat loss, hunting and dog attacks (Medri et al 2006;Hayssen 2011;Miranda 2014). In the present study, except for the collared anteaters that were considered clinically healthy, vehicular strikes and dog bites were the main causes of admission.…”

“…Tamandua tetradactyla, also known as the collared anteater or lesser anteater, is a mammal that belongs to the Xenarthra magnorder, Mymecophagidae family (Naugher 2004;Hayssen 2011), and is considered an arboreal and terrestrial opportunist (Naugher 2004;Medri et al 2006). In South America, the species is distributed over the northern and central regions (Hayssen 2011).…”

“…In South America, the species is distributed over the northern and central regions (Hayssen 2011). The species is found in all types of biomes in Brazil, but in the Pantanal it lives mainly at the edge of the forest (Desbiez & Medri 2010;Miranda 2014).…”

“…The color of the fur is usually pale tan or golden, and may or may not have a black vest or collar (Hayssen 2011;Miranda et al 2014). Color variation and morphological differences may occur according to territorial origin; for example, in Brazil, individuals from the northern portion of the country present a darker color than those from the Atlantic Forest (Miranda 2014).…”

Deforestation and road construction have inflicted negative effects on wildlife populations. To contribute to the comprehension and preservation of wildlife species, this study aimed to evaluate collared anteater presented to a reference center located in São Paulo state, Brazil. Furthermore, the locations where the animals were most frequently found were determined. Data on collared anteaters (Tamandua tetradactyla) examined at the Center for Medicine and Research in Wild Animals (CEMPAS) were evaluated retrospectively for a period of 13 years. A total of 46 collared anteaters was examined, comprised of 14 males, 10 females, and 22 without identifying information. On average, adult males weigh 4.41 kg while adult females weigh 4.95 kg. The most common admission circumstance was vehicular strikes (36.96%), followed by dog bites (21.74%); 23.91% were considered clinically healthy. Animal outcomes were 36.96% (n=17) reintroduced, 34.78% (n=16) fatalities, 15.22% (n=7) transferred to other institutions, and 6.52% (n=3) escaped from the enclosure; and 6.52% (n=3) presented no medical record information. The collared anteaters were found mainly in the municipal areas of Botucatu (21.73%), São Manuel (17.39%), Lençóis Paulista (6.52%), and Bauru (4.34%), with SP-300 being the main highway associated with the occurrences. In conclusion, the main cause of lesion in the collared anteaters evaluated in this study was vehicular strike that that led to death. However, including all collared anteaters at least half of them had a positive outcome. Keywords:Wild animal, highway, clinical evolution, anteater.

“…In this study, similar results were obtained, since the animals classified as level 0 had smaller cranial measurements than those classified as level 1 and 2. It is known that immature individuals of both giant and lesser anteaters have smaller body dimensions than sub-adults and adults (Nowak, 1999;Richard-Hansen et al, 1999;Hayssen, 2011). Then, the age classification by assessing the level of obliteration of the sutures may be a valid technique to estimate an age group for these species.…”

ABSTRACT. This study aimed to examine the relationship between skull size and the level of cranial vault suture closure. A total of 50 Myrmecophaga tridactyla Linnaeus, 1758 and 178 Tamandua tetradactyla Linnaeus, 1758 skulls were analyzed in relation to 18 skull dimensions. The skulls were grouped into three levels of suture closure: no sutures closed (level 0), one or all the fallowing sutures closed: interfrontalis, sagitalis and coronalis (level 1) and all sutures closed (level 2). The results indicated that among the 18 variables measured, 17 showed significant differences (p ≤ 0.01) between level 0 and level 1 skulls of T. tetradactyla; as well as between level 0 and level 1, and level 0 and level 2 skulls of M. tridactyla. M. tridactyla level 1 and level 2 had no significant difference among any of the 18 dimensions. The foramen magnum height in both species showed no significant difference (p > 0.05) among any suture categories. In principle, suture closure level and cranial dimensions are related. The specimens with larger cranial dimensions showed greater number of cranial vault sutures closed for both species of anteaters. Tamandua tetradactyla and M. tridactyla specimens with none of the cranial vault suture closed have a foramen magnum height similar to those with cranial vault suture closed.KEYWORDS. Age, anteater, cranial morphology, xenarthra. RESUMO.Morfometria craniana e suturas da abóboda de Myrmecophaga tridactyla e Tamandua tetradactyla. O presente estudo teve como objetivo examinar a relação das dimensões do crânio e o grau de fechamento das suturas da abóboda craniana. Foram analisados 50 crânios de Myrmecophaga tridactyla Linnaeus, 1758 e 178 de Tamandua tetradactyla Linnaeus, 1758 em relação a 18 dimensões do crânio. Os crânios foram divididos em três grupos quanto ao grau de fechamento da sutura: nenhuma sutura fechada (grau 0), uma ou todas das seguintes suturas fechadas: interfrontalis, sagitalis e coronalis (grau 1) e todas as suturas fechadas (grau 2). Os resultados indicaram que das 18 dimensões 17 apresentaram diferença significativa (p ≤ 0,01) entre grau 0 e grau 1 de T. tetradactyla; entre grau 0 e grau 1, e grau 0 e grau 2 de M. tridactyla. Indivíduos grau 1 e grau 2 de M. tridactyla não apresentaram diferença significativa em nenhuma das 18 dimensões. A altura do forame magno nas duas espécies não apresentou diferença significativa (p > 0,05) entre nenhuma das categorias de sutura (grau 0, grau 1 e grau 2). Em princípio, o nível de fechamento da sutura e as dimensões cranianas estão relacionados. Os espécimes com dimensões cranianas maiores apresentaram maior número de suturas de abóbada craniana fechadas para ambas as espécies de tamanduás. Os espécimes de T. tetradactyla e M. tridactyla sem sutura da abóbada craniana fechada possuem altura do forame magno semelhante àquelas com sutura da abóbada craniana fechada.

Studies on the role of natural predatory instincts in captive‐born mammalian myrmecophagy are rare. Consequently, researchers rely extensively on case reports to learn more about the contexts in which predatory behavior occurs among such animals. In this study, we recorded an uncommon case of a captive‐born southern tamandua ( Tamandua tetradactyla ) that accidentally escaped from a zoo into a nonnative habitat in Asia. The southern tamandua was found alive 3 months later. Two fresh fecal samples were obtained, and the diet composition was examined. Three termite species (one family, three genera), and 14 ant species (four subfamilies, nine genera) were identified in the fecal samples. The studied southern tamandua preyed on terrestrial and arboreal ants and termites, as the wild populations of its species do. Ants of the subfamily Myrmicinae and termites of the subfamily Nasutitermitinae were the most abundant prey items in the samples, which is consistent with related reports on the wild populations. Soldier ants constituted <1% of the prey items in the fecal samples, suggesting that the southern tamandua likely avoided preying on ants of the soldier caste. Fungus‐growing termites Odontotermes (Isoptera: Macrotermitinae), which are not native to neotropical regions, were also ingested by the southern tamandua. This study provides information on how a captive‐born mammalian myrmecophagy applies its natural feeding instincts in nonnative natural settings.
