Poster for Marine Mammal Symposium

Main findings: 

  • Feeding episodes occur during flooding and ebbing tide periods.
  • Preference for shallow waters (mud flats) or river channels.
  • Terminal buzzes are related to prey capture like in other odontocetes.
  • Buzzes are longer and emitted more often than other odontocetes.
  • Inter-click interval can be used to identify feeding events.
  • Body rotation might facilitate prey capture in shallow water.
