Resumen
Frilled sharks are rarely observed and limited information is available regarding their
life history. The global number of records for these sharks does not exceed 40, with
most sightings reported in the Western Pacific Ocean. In 1976, one specimen was
recorded for the first time in the South East Pacific Ocean; however, this study
provides new evidence for the presence of Chlamydoselachus anguineus in Chilean
waters, extending its distribution range 850 km south of the previous record. The
morphological features of all specimens from Chile are discussed, supplementing
previous observations and adding to the existing knowledge on this species in the
Pacific Ocean.
