In his day Amphioxus (now _Branchiostoma_) was often cited as proving the theory of recapitulation, and Garstang was the first scientist to try to repudiate that theory. One of his last communications was to the effect that Amphioxus most nearly represented a paedomorphic neotenous larva of a Cyclostome. As in gene expression studies, the neural wiring diagram of a late larva indicated that amphioxus lacks a telencephalon, but does have a diencephalon, a small midbrain, and hindbrain.

The writers of Digestive System Of Amphioxus Diagram have made all reasonable attempts to offer latest and The amphioxus CNS lacks ventral roots; the paraxial muscles send muscle tails to synapse directly with motor neurons at the periphery of the CNS (Flood 1968). However, the amphioxus CNS does have dorsal roots, which probably receive sensory input and are serially arranged like the dorsal roots of vertebrates (Wicht and Lacalli 2005). In this article we will discuss about the external morphology of branchiostoma with the help of suitable diagrams. Shape, Size and Colour: Branchiostoma is about 3.5 to 6.0 cm in length.
