Amphioxus

Synopsis: This film has been made mainly from a series of photomicrographs, many of which are unique, of the living amphioxus, in combination with diagram animation. Demonstrates the role of the notochord in undulatory swimming and contrasts the ciliary feeding of the adult living in sand with the macrophagy of the planktonic larva. Development of larval specialisations and their replacement by adult adaptations are shown. At metamorphosis a transitory unspecialised form exists suggesting the kind of animal that might once have been ancestral to the vertebrates.
