Chordata (chordates o chordatos) es un phylo animal characterisate per le presentia de un chorda neural tubular dorsal o notochorda, sia durante tote le disveloppamento, sia in alicunes del phases de lor vita. Il ha tres subphylos: Cephalochordata, Tunicata e Vertebrata.
Definition
1 = cerebral protuberantia
4 = coda post-anal
14 = apertura buccal
16 = sensor de lumine
Le chordatos forma un phylo — un gruppo de animales con un commun plan del corpore — organismos que ha tote le sequente:
