Bagwhale

A baleia-bolsa (Berardius minimus) é uma baleia-bicuda de porte médio do Pacífico Norte, reconhecida recentemente como espécie distinta por meio de estudos genéticos e morfológicos. Seu estado de conservação é de dados insuficientes (DD), e seus hábitos em águas profundas tornam muito difícil a realização de censos sistemáticos da população.
