Hace 1 día · Arthropods ( / ˈɑːrθrəpɒd / ARTH-rə-pod) [20] are invertebrates in the phylum Arthropoda. They possess an exoskeleton with a cuticle made of chitin, often mineralised with calcium carbonate, a body with differentiated ( metameric) segments, and paired jointed appendages. In order to keep growing, they must go through stages of moulting ...

Hace 3 días · Bilateria. O clado Bilateria inclui todos os metazoários que apresentam corpos organizados em um eixo antero-posterior (ou sagital) fazendo com que possam, em sua grande maioria, serem divididos em duas metades simétricas. Os animais bilaterais, também chamados triploblásticos (Triploblastica) apresentam três camadas embrionárias - a ...
