A simulation of biological water quality monitoring of an inland water system on the Seven-Trent. Students interactively sample the macro invertebrate populations, use a key to identify the samples and then...
Photographed from an oscilloscope screen. Deals with simulation by analogue computer of the invertebrate shell morphology and the visualisation of mathematical analysis. The development of typical univalve,...
A compilation of sequences in the lobster’s life cycle showing feeding, moulting, copulation, egg-bearing and the production of planktonic larvae. The soundtrack guides the view through these events,...
Sea urchins and snails, worms and whales, crabs and crayfish - the ocean seethes with a wealth of animal forms. Can we tease any underlying patterns from this immense diversity? This programme looks at a...
Part 2: Explains reproduction using three species as examples to include both oviparous and viviparous rotifers. Most rotifers are female and most of the time reproduce asexually. One group can only...
Looks at the evolution, phylum characteristics, major classes, larval development and natural history of flatworms. Observes structure, behaviour and life cycles of planarians and other free-living...
Species specific reaggregation in dissociated sponge cells is shown in two species of sponges, ‘Haliclona occulata’ and ‘Microciona prolifera’. The dissociated cells appear to move randomly by the...
Looks at the evolution, phylum characteristics, major classes, larval development and natural history of annelids. The phylum ‘Annelida’ is made up of segmented worms in three classes: Oligochaetes...
Looks at the evolution, phylum characteristics, major classes, larval development and natural history of the phylum ‘Mollusca’, which is made up of four major classes: ‘Polyplacophora’ (includes...
Shows how nematodes, rotifers, bryozoans, and some minor phyla, including a number of human parasites, reproduce, carry out their physiological processes, capture prey and exploit their ecological resources....
