blue whale

O maior animal que já viveu na Terra, as baleias-azuis podem atingir 33 metros e 200 toneladas — seus corações sozinhos pesam tanto quanto um carro pequeno. Encontradas em todos os oceanos, migram entre áreas de alimentação polares e áreas de reprodução tropicais. Filtradores que consomem até 4 toneladas de krill diariamente. Em perigo, com populações globais estimadas em 10.000–25.000 após a quase extinção causada pela caça baleeira no século XX.

The Cokerite Palm (Attalea maripa), also known as Maripa Palm or Inajá, is a solitary, tall-growing feather palm in the family Arecaceae, distributed across the lowland rainforests, forest edges, and floodplain forests of Amazonian South America, primarily in Brazil and Colombia, with additional records from Venezuela, Guyana, Suriname, French Guiana, Peru, Bolivia, and Ecuador. Trees typically reach 15–25 metres in height, producing large pinnate fronds and impressive clusters of ovoid fruits with an oily, yellow-orange outer mesocarp surrounding a hard-shelled nut. The palm is widely used by indigenous and traditional communities throughout Amazonia: the oil-rich mesocarp of the fruits is eaten fresh and used to produce a nutritious food paste; the apical bud (palm heart) is consumed; the young leaves are used for basket weaving and thatching; and the trunk wood serves in construction. Attalea maripa frequently regenerates vigorously in disturbed forest and pasture margins, indicating tolerance for light disturbance. It plays an important ecological role as a food source for large frugivores including tapirs, peccaries, and macaws that help disperse its large seeds. The species is assessed as Least Concern by the IUCN, with stable populations across its broad Amazonian range.
