Uma curiosidade interessante sobre os tucanos é que, apesar de seu bico ser muito grande e parecer pesado, ele é surpreendentemente leve. O bico dos tucanos é composto principalmente por queratina, a mesma substância que forma as unhas e o cabelo dos humanos, e é preenchido por uma estrutura semelhante a uma esponja, com câmaras de ar. Essa estrutura permite que o bico seja grande e imponente, mas sem adicionar muito peso, o que facilita o voo e a alimentação do tucano. #animais #viraliza
