Aim of this assay is to study the anatomy of the lymphatic system of the capybara (Hydrochoerus hydrochaeris). Number, shape and size of head and neck lymphocenters, as well as their relationships with the neighboring structures, are described in this work. Ten capybara cadavers were dissected and findings were documented photographically. Mandibular and parotid lymph nodes were found in the head, and cervical lymph nodes (superficial, deep cranial, deep half and deep flow) were found in the neck. Disposition of these lymph nodes is similar to that of the swine, although retropharyngeal nodes were not observed. It is expected that lymph nodes localization will be useful to value the aptitude of H. hydrochaeris meat for human consumption.
