Blue-and-yellow Macaw

One of the most striking and widely kept macaw species, blue-and-yellow macaws display brilliant cobalt blue upper parts contrasting with vivid yellow underparts and green forehead. They inhabit forest, woodland, and savanna from eastern Panama through Venezuela, Brazil, and Bolivia to Peru and Ecuador. Highly intelligent, they live in pairs or small flocks, feeding on palm nuts, seeds, and fruit. Popular in aviculture for over 400 years, they can live 80+ years in captivity.

common hydra

<em>Hydra vulgaris</em>, commonly known as the common hydra, is a small freshwater cnidarian in the family Hydridae. Its conservation status has not been formally evaluated by the IUCN. The species is recorded from Denmark, Norway, and Sweden, with its native range understood to encompass Europe broadly. It typically inhabits slow-moving or still freshwater bodies such as ponds, lakes, and streams, where it attaches to aquatic vegetation or submerged substrates. The common hydra is notable for its remarkable regenerative capabilities and has been the subject of substantial biological research. Diet information for this species is not available in current records. Biological traits of this species remain poorly documented in the scientific literature.
