Anteaters are normally diurnal but they can become nocturnal where persecuted. They swim well and will readily go in water. They sleep curled up with the head between the forelegs and the tail covering the body. Their main predators, pumas and jaguars, are very careful to avoid the front claws which can cause serious injuries or death. Anteaters have weak vision, but a good sense of smell. Once a termite or ant nest is opened the anteater will eat until the stings from the insects become too frequent and painful. For this reason they are not territorial but rather nomadic. One anteater can consume 35,000 to 50,000 insects per day. As a result of habitat loss and hunting it has disappeared in many parts of its former range. It is hunted mostly for sport. Unlike other anteater species, the giant anteater does not climb trees.
