In others, the key attraction is adventure travel in a remote area, with wildlife as am added bonus, e.g. narwhal from a sea kayak in the High Arctic, condor from horseback in Patagonia, caiman at night from a dugout canoe on the Amazon. The animals are visited only occasionally, are not habituated, may by hunted by local residents (or other tourists), and must often be stalked to be seen.
Ln others again, the key attraction is an adventure activity, with wildlife as a primary target, e.g. watching polar bear or sperm whale from a helicopter, hippo from a canoe, whales from a speedboat. The tourist activity itself may potentially create significant impacts on the wildlife concerned, considered either at the level of individual animal welfare, or conservation of species populations.
