Lagarto, Iguana iguana, Glândula femoral, Morfologia, Pantanal, BrasilResumo
Glândulas femorais são especializações da epiderme presentes em alguns lagartos, e muito utilizadas para taxonomia e sistemática do grupo. Este trabalho apresenta detalhes complementares sobre essas glândulas, especialmente quanto à sua descrição morfológica. Indivíduos machos adultos de Iguana iguana foram coletados na região do Pantanal, Brasil, no período de novembro de 1998 a julho de 1999. As glândulas foram retiradas e analisadas em microscopia de luz e microscopia eletrônica de varredura. As glândulas femorais de I. iguana são constituídas por três regiões: basal secretora, canal de secreção e poro. São glândulas do tipo tubular ramificada holócrina. Parecem não apresentar variações na sua morfologia durante o ano.
