Alequim

O tubarão-branco é o maior peixe predador da Terra, podendo atingir 6 metros de comprimento e 2.000 kg, habitando águas costeiras e oceânicas frias em todos os principais oceanos. São predadores de topo que empregam ataques de emboscada por baixo, direcionados principalmente a mamíferos marinhos, peixes de grande porte e aves marinhas. Apesar de sua terrível reputação, ataques não provocados a humanos são extremamente raros. Classificado como Vulnerável (VU), com populações em declínio devido ao corte de barbatanas, captura acidental e pesca direcionada, apesar das proteções legais vigentes em muitas jurisdições.

common bubble snail

The common bubble snail (<em>Akera bullata</em>) is a marine gastropod mollusc found in the coastal waters of Denmark, Norway, Portugal, and Sweden. This species typically inhabits terrestrial and aquatic environments including forests and freshwater-adjacent marine areas, often occurring in shallow subtidal and intertidal zones of temperate European seas. It is classified as Least Concern on the IUCN Red List. As a member of the family Akeridae, the common bubble snail is characterized by its thin, fragile shell and its ability to swim briefly by flapping its large, wing-like parapodia. The species often forages on algae and detritus in sandy and muddy seafloor habitats, particularly in sheltered bays and estuaries. The common bubble snail typically aggregates in large numbers during the spawning season, producing gelatinous egg masses. Biological traits of this species remain poorly documented in the scientific literature.
