Branchiostoma lanceolatum
Branchiostoma lanceolatum, the European lancelet or Mediterranean amphioxus, is a lancelet in the subphylum Cephalochordata. In short, TLRS in amphioxus propose a paraphyletic relationship with the vertebrate TLR lineage.

Isolation and developmental expression of the amphioxus Pax-6 gene ...
Pax-6 genes have been identified from a broad range of invertebrate and vertebrate animals and shown to be always involved in early eye development. Therefore, it has been proposed that the various types of eyes evolved from a single eye prototype, by a Pax-6-dependent mechanism. Here we describe the characterization of a cephalochordate Pax-6 gene.

Branchiostoma belcheri
Amphioxus or lancelets (Branchiostoma) are members of the Chordata phylum of which all members have a notochord at some point while they are alive. Later observations concluded that amphioxus in waters other than the Ariake Sea and the Amakusa belonged to B. belcheri var. tsingtauense, while those
