CORDADOSCaracterísticas embrionárias → notocorda →fendas branquiais faringeanas → tubo nervoso dorsal → cauda pós anal

CLASSIFICAÇÃO DOS CORDADOS

• PROTOCORDADOS→ notocorda regride ou permanece na fase adulta

→ exclusivamente marinhos

→ exemplos : ascídia, anfioxo

CRANIADOS OU VERTEBRADOS→ a notocorda se transforma em crânio e vértebras

→ marinhos, dulcícolas e terrestres

→ exemplos : garoupa, jacaré, leão

PROTOCORDADOS Ascídia Anfioxo

Balanoglossus

CRANIADOS OU VERTEBRADOS

→ AGNATOSORGANISMOS SEM MANDÍBULA

exemplos : peixe-bruxa , feiticeira

→ GNATOSTOMADOSORGANISMOS COM MANDÍBULA

* PEIXES → condríctes e osteíctes

* TETRÁPODAS → anfíbios, répteis,

aves e mamíferos

AGNATOSlampréia peixe-bruxa

RÉPTEIS* primeiro grupo de vertebrados a ocupar efetivamente

o ambiente terrestre

→ pele impermeável

→ fecundação interna

→ ovos com casca calcária

→ surgiram a cerca de 300 milhões de anos

→ répteis primitivos originaram os dinossauros, os mamíferos,

as aves e os répteis atuais

→ durante um período de aproximadamente 150 milhões de anos

(período Jurássico) os dinossauros dominaram o planeta,

ocupando todos os habitats
