| So that in this respect the ascidian larva is nearer to the original type than the tadpole or any other existing animal. |
| When retracted it has the aspect of an ascidian, and for a time was supposed to belong to that group. |
| Chabry had published in 1887 some interesting results on the ascidian egg, which strongly supported the Roux-Weismann theory. |
| Castle77 observed and studied the phenomenon of self-sterility in an ascidian, Ciona intestinalis, which is hermaphroditic. |
| The ascidian has only one eye inside its useless brain, while the tadpole and all other vertebrates have two from the very first. |
| The ascidian when born is a tiny, free-swimming, tadpole-like creature with a slender finned tail. |
