摘要

本文通过对阿根廷查科Bermejo省私人野外采集的成年和幼年黑眼鱼标本的分析，确定了黑眼鱼的食性和消化道的组织形态。2015年3月至6月每月进行一次抽样。对29只标本进行了采集、测量、性别鉴定和解剖，以获得消化内容物和其形态学样本。结果表明，其有较高的噬蛹倾向;超过95%的猎物被确认为蚂蚁。在脊椎动物中，胃肠道系统的组织形态主要由四层组织组成:粘膜、粘膜下层、肌肉和浆膜。本研究对蟾科无尾目动物的生物学和自然史的认识有重要的贡献，特别是黑眼蟾属，目前其保护状况受到广泛关注。

Diet and histomorphological study of the gastrointestinal system of melanophryniscus klappenbachi (anura: bufonidae)

The diet and histomorphology of the digestive tract of Melanophryniscus klappenbachi were determined by the analysis of adult and juvenile specimens collected in a private field in Bermejo department, Chaco, Argentina. The sampling was carried out monthly from March to June 2015. 29 specimens were collected, measured, sexed, and dissected for the obtainment of the digestive content and his- tological samples. The results showed a high tendency towards myrmecophagy; more than 95% of the recovered prey items were identified as ants. The histomorphology of the gastrointestinal system consisted of the main four layers of tissue observed in vertebrates: mucosa, submucosa, muscular, and serosa. This study constitutes a contribution to the knowledge of biology and the natural history of anurans of the Bufonidae family, especially the genus Melanophryniscus, which currently receives a great amount of attention regarding its con- servation status.
