Background: The black-tufted ear marmoset, Callithrix penicillata, is an endemic primate from Brazil, distributed among Cerrado and Atlantic Forest vegetation. Most of the congenital malformations from the spinal cord arises from failures in the neural tube closure. Those failures result in an opened dorsal arch of one or more vertebrae are referred as spina bifida. In the occulta form, the condition is asymptomatic because spinal cord and meninges remain in the normal position. When the meninges become distended with fluid (myelomeningocele), the phenomenon is called spina bifida cystica. In these cases, the spinal cord protrudes into the subarachnoid space and the nerve roots may become displaced, causing neurological deficits. When this defect allows leakage of cerebrospinal fluid through the skin, it is characterized as the open form. This article reports the findings of the first case of spina bifida occulta in an adult male of Callithrix penicillata collected dead in a brazilian highway.Case: A cadaver of a young-adult, male, black-tufted ear marmoset (Callithrix penicillata) was founded at km 103 of BR-116 highway in the city of Guapimirim, Rio de Janeiro State, Brazil. The cadaver was necropsied at the Laboratory of Animal Anatomy from Universidade Castelo Branco, in the city of Rio de Janeiro, Brazil. During macroscopic evaluation it was possible to identify a normal b
