Marcas de mordida indicavam que a maior parte de sua barbatana dorsal também havia sido mastigada Elianne Dipp/Pexels

As orcas – referidas no estudo como “baleias assassinas” – atacaram sua presa por 20 minutos, que tentou usar a cauda como mecanismo de defesa

No mesmo ano, um outro grupo de orcas matou um filhote de baleia azul Jose Vargues/Pexels

As assassinas de fêmeas adultas podem ser mais propensas a iniciar ataques porque têm filhotes para alimentar e, portanto, exigem sustento com mais frequência do que os machos adultos
