Because of their strength, jaguars have no predators other than humans. They mark their territory with scent. They are very efficient hunters, creeping close to their prey before pouncing. Although they stay mainly on land, they can swim well. They will wade into water to catch fish.
They also climb trees, and sometimes pounce on their prey from a hiding place up a tree. They hunt at different times of the day, depending on the where their territory is, so they can’t be easily classified as diurnal (daytime hunter), nocturnal (night time hunter) or crepuscular (hunting at dawn and dusk). Jaguars rarely attack humans.
