Chaetognatha
Chaetognatha, que significa garras de cerdas, e vulgarmente conhecido como worms de seta, são um filo de vermes marinhos predatórios que são um dos principais componentes do plâncton em todo o mundo. Cerca de 20% das espécies conhecidas são bentônicas e podem juntar-se a algas e rochas. Eles são encontrados em todas as águas marinhas, desde águas tropicais de superfície e piscinas de maré rasas até o mar profundo e as regiões polares. A maioria dos chaetognaths são transparentes e têm forma de torpedo, mas algumas espécies de profundidade são laranja. Eles variam em tamanho de 2 a 120 milímetros. Existem mais de 120 espécies modernas atribuídas a mais de 20 gêneros. Apesar da limitada diversidade de espécies, o número de indivíduos é grande.
