Documentary about the wildlife in the coral reefs of the Red Sea. This is an intriguing account of the Red Sea’s underwater “cities”, delving under their seemingly calm exterior to reveal a world rife with trickery and corruption. Specially modified cameras record dawn and dusk in a land where all life seems to either attack, or cunningly avoid, other species. Lionfish patiently wait to ambush their prey, cleaner wrasses warily attend to groupers and a cornetfish attack sparks pandemonium in a silverside shoal. The latest underwater photography provides a spectacular view of the battles that rage beneath the surface. Narrated by David Attenborough he brings to life this extraordinary world of strange intelligence, trickery and ruthless predation. This is the version shown on UKTV.
