Hypertrophy of sebaceous glands on the snout as a secondary male sexual character in the Capybara, Hydrochoerus hydrochoeris.

Authors


Summary.

A relatively bare, raised area appears on the dorsum of the snout, of the male Capybara as maturity approaches. It consists of greatly hypertrophied sebaceous glands, the largest of which open directly onto the surface. Possibly it serves as a scent organ to attract the female.
