Description
This programme illustrates the plant and animal life of the oceans and examines some part of the adaptations that allow creatures to live in particular environments. You will see film shot deep in ...the Pacific Ocean where fish scavenge on the corpses of other fish, extracts from the round-the-world voyage of Galathea in the 1950s, and in British waters, the animal and plant life of the Firth of Clyde.

| Footage description: | Film of animals on the ocean floor at a depth of several kilometers scavenging the corpse of a fish. Commentary by Peggy Varley introduces the programme. The above film continues for a few seconds then shots of Peggy Varley on the shore of the Firth of Clyde. She points out the importance to the food chain, of primary producers which trap the sun's energy at or near the surface. Film of life in the euphotic zone showing a rich variety of plants and animals including winkles, limpets, sea urchins, starfish, crustaceans, worms and fish, Also film, under magnification, of the microscopic life found in this zone, both plant and animal. Many of these microscopic animals are larval stages of the animals shown above. Film of a beam trawl being hauled aboard ship and the contents being examined. The animals were gathered in the Firth of Clyde from a depth of about 120 metres. Commentary by Peggy Varley describes the animals. Shots of a scampi, hermit crab, brittle star, sea urchin and whelk. Film of a grab, an apparatus which takes a sample of sea bottom mud, being hauled aboard and of the contents being examined. Shots of bi-valve molluscs and annelid worms. Commentary by Peggy Varley. Peggy Varley examines some specimen from a different area of the Firth of Clyde taken from a depth of about 60 metres; Shots of spidercrabs, hermit crab, anemone, spring starfish, red star (and other echinoderms), sea urchins and scallops. Underwater film of animals in deeper waters at the edge of the continental shelf and then of fish from deeper waters still. Also shots of specimen brought to the surface in trawls - ling fish, rat fish, spider crab and other crustaceans. Film shots of an oceanographic research vessel (very brief) and of life at various depths of the ocean. Commentary by Peggy Varley points out the various species as they appear. She points out, particularly, the unique system of finding a mate adopted by the sea angler fish. Shots of a deep sea trawl being opened and the contents being examined. Commentary by Peggy Varley continues. More film shots (as at beginning of the programme) of abyssal animals scavenging the corpse of a dead fish. |
