🐾Bowhead whale
As baleias-da-groenlândia (Balaena mysticetus) também são conhecidas como baleia-da-gronelândia, baleia-franca-do-ártico, baleia-franca-da-gronelândia ou grande-polar. Em inglês são chamadas de bowheads, que ao se traduzido significa cabeças de lombada. São os únicos membros da família Balaenidae (subordem Mysticeti, ordem Cetacea). E vivem a maior parte do tempo nos oceanos com latitudes setentrionais. As baleias-da-groenlândia nunca foram vistas no Hemisfério Sul. É uma baleia de cor escura, desprovida de barbatana dorsal e que pode crescer de 14 a 18 metros de comprimento. Possuí um corpo pesado de 75 a 100 toneladas e a maior boca de qualquer animal. A baleia-da-groenlândia foi um grande alvo da caça a baleia e as populações foram severamente reduzidas devido a isso. Das cinco sub-populações de baleias-da-groenlândia pelo menos três estão listadas como Em Perigo, uma como Vulnerável e uma como Pouco Preocupante de acordo com dados da UICN.
