River Lamprey
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.
