Baleia jubarte

Entre as baleias grandes mais acrobáticas, as baleias-jubarte são famosas por seus cantos complexos e evocativos entoados pelos machos durante a temporada reprodutiva, podendo durar horas e evoluir ao longo do tempo. Atingindo 16 metros e 30 toneladas, realizam as migrações mais longas de qualquer mamífero. Encontradas em todos os oceanos, alimentam-se de krill e peixes pequenos usando a técnica cooperativa de rede de bolhas.
