It even looks like a tiny tadpole, and has a nerve cord down its back, similar to the nerve cord found inside the vertebrae of all vertebrates.

Andrew Williams / Shutterstock.com Asexual reproduction takes place in tunicates and in some vertebrates (females of some fish and lizards Because they do not have the braincase, or cranium, of a vertebrate, lancelets are Tunicates also have an atrium, but its evolution is probably Tunicates and not cephalochordates are the closest living relatives of vertebrates. Nature. 439, (7079), 965-968 (2006).

Based on molecular analysis, vertebrates appear to be more closely related to lancelets (cephalochordates) than to tunicates (urochordates) among the invertebrate chordates. This evidence suggests that the cephalochordates diverged from Urochordata and the vertebrates subsequently diverged from the cephalochordates.

Adult tunicates may be either solitary or colonial forms, and some species may reproduce by budding. Most tunicates live a sessile existence on the ocean floor and are suspension feeders . However, chains of thaliacean tunicates called salps (Figure 3) can swim actively while feeding, propelling themselves as they move water through the pharyngeal slits.

Animals in the phylum Chordata share four key features that appear at some stage of their development: a notochord, a dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail (Figure 15.5.3).
