The presence of magnetic material in tissues of lateral line and ocellar spot of tomtates Haemulon aurolineatum is shown using the ferromagnetic resonance technique. For the first time magnetic material is reported in the ocellar spot. The magnetic material detected in these structures of H. aurolineatum suggests that this species could use magnetic orientation during its nocturnal foraging, and the relevance and role of this material with respect to schooling movements is discussed.
