Chordates {tunicate}| {sea squirt} (Urochordata) can live in tropical oceans, be sessile or floating, and have translucent cellulose covers, with hole for incurrent siphon and hole for excurrent siphon. They filter-feed to catch phytoplankton. They can bud. Larvae have chordate characteristics, but adults have gill slits. Vertebrates evolved from tunicate larvae.
