their nose
Animals such as pigs, anteaters, and tapirs have snouts. They use their snouts to root for food, dig, and sniff out scents in their environment. The snout helps them to locate and gather food efficiently.
The answer to this question is all animals.
A cheetahs food is located everywhere they use their speed to hunt down the prey. They climb trees to locate other animals. Cheetahs chase gazelles for main ways to food.
Obviously they use their highly effective sense of smell to locate their food, but they also can use their memories to locate their food storage area both in their cages and in the wild.
Lobsters use their antennae and chemosensory organs to navigate their environment and locate food.
Condors have very good eyesight and also very a good sense of smell. They use both to locate dead animals to eat.
They use echolocation (a form of ultrasonic ranging) to locate their food.
Animals can get tracking devices implanted in them (microchips) so their owners can locate them if lost.
None ! Some animals such as bats, use ultra-sonic sound to locate prey, and 'see' in the dark.
Caecilian rely on small sensitive tentacles on its head to locate the worms, insects, snails and other small animals it eats. They also locate their food by taste and smell.
many animals ( dolphins, bats, insects, etc.) use sonic (sound) wave to locate positions, food,etc. By studying these animals we can find out how to use and read sonic waves and how they relate to different locations, movements, solids, liquids, gases,etc.
Arboreal animals get their food by foraging in trees for fruits, leaves, insects, and small animals. They may also use specialized adaptations like long limbs or prehensile tails to reach food in high or narrow spaces. Some may also have keen senses, such as sharp eyesight or a strong sense of smell, to locate food in their arboreal environment.
