Contribuição ao estudo anatômico da dura-máter do Bradypus torquatus (Linnaeus, 1758) e Bradypus variegatus (Schinz, 1825)

open access: yesBrazilian Journal of Veterinary Research and Animal Science, 2005
Pesquisas em neurociências têm contribuído para elucidar a história dos animais na terra, contudo diversos animais silvestres da América do sul ainda não foram estudados. O bicho preguiça, ameaçado de extinção, por sua alta especificidade e especialização alimentar pode nos fornecer informações sobre a história evolutiva animal.
