Predator and prey relationships in rivers include bears and salmon in Alaska; mayflies and trout in Britain; and kingfishers and minnows in Europe. Also: piranhas in Venezuela.
Desert environments are examined. Included: a spider that rolls down dunes to evade predators; hyenas that take advantage of seals on a beach. Also: rats, hawks and vipers.
Life and death dramas take place in the seas of the world. Off the coast of West Africa, sardines are herded by dolphins and engage with gannets from the air, while schools of jacks use the Great Barrier Reef to trap their prey.
The sky is a vast battlefield where both predator and prey endure the constraints of gravity. The aerial conflicts of falcons and their pigeon prey are examined, along with the hunt for bats by hawks outside of Texas caves.
Wetlands create a landscape in constant flux, merging wildlife combatants.
Grasslands are the classic wildlife battleground providing a vast, open field of combat where grazers can attract a host of hungry carnivores. The savannas of Africa host contests of speed between gazelles and cheetahs.
