- Jaguars once roamed from southern Brazil all the way to the United States, as far north as the Grand Canyon. Today the northernmost population lives less than 150 miles south of the US-Mexico border.
- The jaws of a jaguar are so powerful that jaguars in captivity have been known to leave dents in bowling balls and can penetrate the shell of a turtle (one of their favorite meals in the wild).
- Jaguars have an extremely varied diet in the wild, and are known to dine on deer, birds, capybara, tapir, fish, caiman and even monkeys and squirrels that venture too far down from the trees of the jungle.
- Despite being a relatively small country, Costa Rica's rainforest is home to 5% of the Earth's plant and animal species.

- Wolves generally avoid contact with humans, but in the past decade have been responsible for two human deaths, killing a teacher jogging in Alaska in 2010 and a student in northern Saskatchewan in 2005.
- Wolves hunt in packs both for protection and to be able to bring down larger species of prey. The pack is led by an alpha male and his mate, who are often the only pair in the pack allowed to mate. Others in the pack structure include a beta wolf (who can be either male or female) and an omega wolf, an outsider who tends to be the scapegoat and instigator of play in the group.
- Recent surveys have indicated that both the moose population and the wolf population in Minnesota are growing. In 2013 there were an estimated 4,350 moose (up from 2,760 in 2012) and an estimated 2,641 wolves (up from 1,652 in 2012).
