What evidence of body segmentation do lancelets display?

Lancelets have a somewhat fish-like body. However, the don't have fins or any other limbs. They are not good swimmers, and have a relatively poorly developed tail. Moreover, they do not possess a true form of a skeleton, they just have some gill slits, mouth and that tail I already mentioned.

Hope this helps

Soil? it sounds right when you r3ad it in a sentence

Basalt rock can be rough or maybe smooth
