Urochordata

( uros: tail; chorde: cord)

Habitat: marine

Notochord present only in tail region of tadpole larvae

Adult lack tail and organ for locomotion

Sex: Hermaphrodite

Fertilization: Cross and external

Development: indirect

Examples: Hermania, Salpa, Doliolum

These are barrel-shaped, non-segmented filter-feeding marine animals.

The larval stage usually has a tail and is free-swimming, but it eventually attaches to a hard substrate and loses the tail as it transforms into the adult form.

By the time these organisms are adults, they only display one characteristic of chordates, and that is pharyngeal gill slits.
