Fish, Life, BBC Documentary Series. Episode 4
Fish, the most diverse group of vertebrate animals, thrive in the world s rivers, lakes and oceans. Slowmotion footage reveals the behaviour of some of the fastest fish in the sea, sailfish and flying fish. The latter gather in large numbers to lay their eggs on a floating palm frond, which sinks under the weight. The eggs of weedy sea dragons, found in the shallow waters off southern Australia, are carried by the male. In the fertile seas of the western Pacific, competition is fierce.
