An adult male pygmy sperm whale, Kogia breviceps (De Blainvillei,
1838) (Physeteridae), 2.73 m long was found stranded on Cacimba do Padre
beach, Fernando de Noronha archipelago (3 degrees 51'S; 32 degrees 25'W),
Brazil on 2 May 1987. At necropsy, nematodes were collected from the
stomach, fixed in 70 GL alcohol and cleared in beechwood creosote. Their
identification was based on JT Davey (1971) and D Gibson (1983).
Measurements were made with the use of a calibrated filar micrometer with
the range given in micrometers followed by the mean in parenthesis, and
number of specimens measured. Studied material is deposited in the
Helminthological Collection of the Instituto Oswaldo Cruz (CHIOC), Rio de
Janeiro, Brazil.
