The Amur leopard is solitary. Nimble-footed and strong, it carries and hides unfinished kills so that they are not taken by other predators. It has been reported that some males stay with females after mating, and may even help with rearing the young. Several males sometimes follow and fight over a female. They live for 10-15 years, and in captivity up to 20 years.

-The blue whale is the largest animal on the planet, weighing as much as 200 tons (approximately 33 elephants). The blue whale has a heart the size of a Volkswagen Beetle. Its stomach can hold one ton of krill and it needs to eat about four tons of krill each day. They are the loudest animals on Earth and are even louder than a jet engine. Their calls reach 188 decibels, while a jet reaches 140 decibels. Their low frequency whistle can be heard for hundreds of miles and is probably used to attract other blue whales.
