Ballena jorobada

Entre las ballenas grandes más acrobáticas, las ballenas jorobadas son célebres por sus complejos y estremecedores cantos entonados por los machos durante la temporada reproductiva, que pueden durar horas y evolucionar con el tiempo. Alcanzando 16 metros y 30 toneladas, realizan las migraciones más largas de cualquier mamífero. Se encuentran en todos los océanos y se alimentan de krill y peces pequeños mediante la técnica cooperativa de pesca con red de burbujas.
