Jaguars vs. Crocs

Veteran wildlife photographer Steve Winter and cameraman Bertie Gregory capture the remarkable lives of Jaguars in the Pantanal of Brazil. A mother jaguar teaches her cub survival while a determined male jaguar named Scarface dives headfirst into the river to tackle the deadliest of opponents - 6-foot long caiman. Clever capybaras and playful giant otters stick with their family members to avoid being jaguar dinner. (National Geographic)
