"Jaguara" is an Indian word, meaning, he who kills with one leap".
Jaguars are the biggest cats in the Americas and they spend about half their time hunting. They are very fast, short-distance runners and are most active during early evening and night.
Jaguars are also excellent swimmers and can even cross rivers that are several kilometers wide. They are very shy and have home territories that can reach up to 40 square kilometers (15,5 square miles).
Jaguars live in the Amazon forest, which is the largest remaining tropical forest in the world - as large as Western Europe or the USA.
Most of the Amazon rainforest is in Brazil, but parts of it are also in neighboring Guyana, Venezuela, Colombia, Suriname, French Guiana, Ecuador, Peru and Bolivia.
Along with Jaguars, the forest is also home to about 60,000 plant, 1,000 bird and over 300 other animal species. Over 2,000 different species of fish and animals such as the pink freshwater dolphin and the giant otter swim in its river.
Millions of people also live there - in the Brazilian Amazon alone around 20 million people live in the rainforest.
However, the forest is under threat due to human developments and illegal logging, which could lead to the damage or loss of much of Brazil's remaining Amazon forest.
