Despite being found in the wetlands of the Amazon rainforest, jaguars avoid the water like most cats.


Jaguars are actually good swimmers and have been known to cross wide rivers! They are often found living near the water—along lakes, rivers, and in wetlands.

How many muscles does an elephant trunk have?

Up to 10,000 muscles
Up to 25,000 muscles
Up to 40,000 muscles
Up to 75,000 muscles

An elephant trunk has up to 40,000 muscles. By comparison, a human's whole body has around 600 muscles. Elephants use their trunks to suck up water for drinking, greet each other, feed, snorkel when swimming, lift heavy objects, trumpet warnings, and much more.

Which of these statements is true?

Koalas are bears
Koalas have opposable thumbs
Newborn koalas weigh only three ounces
Koalas can be found throughout Australia

Opposable thumbs help koalas climb eucalyptus trees, which are their homes and sole food source. Koalas are marsupials (not bears), found in southeastern and eastern Australia. Weighing less than an ounce at birth, a baby koala finds its way into its mother’s protective pouch, where it stays for up to seven months. Habitat loss is the koala's greatest threat.

How many eggs can sea turtles lay at one time?

Up to 60 eggs
Up to 180 eggs
Up to 240 eggs
Up to 300 eggs

Female sea turtles travel great distances across the ocean and onto shore where they dig a hole in the sand and lay their eggs. They then lay "clutches" of up to 180 eggs at a time. They return about two weeks later to deposit another clutch of eggs, and may return a few more times before the nesting season is over.

Next question >
