The mammaries from carcasses of two female Amazonian manatees were examined. Trichechus inunguis possesses two axillary mammaries beneath the pectoral fins, one on each side of the body. Each papilla mammae has a small hole on its apex--the ostium papillare. The mammaries are covered by a stratified squamous keratinized epithelium. The epithelium of the mammary ducts became thinner more deeply in the tissue and varied from stratified to simple cuboidal. There was no evidence of glandular activity or secretion into the ducts of the mammary glands.
对两只雌性亚马逊海牛尸体的乳腺进行了检查。亚马逊海牛在胸鳍下方有两个腋下乳腺，身体两侧各一个。每个乳头在其顶端有一个小孔——乳头孔。乳腺由复层鳞状角化上皮覆盖。乳腺导管的上皮在组织中越深处越薄，从复层变为单层立方上皮。没有证据表明乳腺有腺体活动或向乳腺导管分泌。
