Description
This programme follows the evolution of fishes from the primitive forms of the early Devonian through to modern forms living today. In particular, the swimming and feeding mechanisms of the Teleost...s and the Chondrichthyans are compared.

| Footage description: | Underwater shots of fish shoals and of individual fish including sharks, tuny, pike, wolf fish, carp and salmon. Commentary points out the vast diversity of fish species found in the world today. Shots of a lung fish and then of a catfish walking on land are shown as examples of specialised adaptation. Shots of a fossil Heterostracan from the lower Devonian and of a model of one of these, Drepanapsis, a jawless armoured fish. Commentary points out the features of this animal which were common among the early fishes. Shots of a fossil Osteostracan, another jawless armoured fish, which appeared later during the mid-Silurian. A model of one of these, Cephalapsis, is used to point out the major distinguishing features of this group. Shots of hagfish and lampreys, the only jawless species to survive beyond the Devonian right up to the present.
