Manatees don’t have blubber like seals and walruses, so they can’t survive long
These frogs are considered one of Earth’s most toxic, or poisonous, species. For example, the golden poison dart frog has enough poison to kill 20,000 mice. With a range of bright colors—yellows, oranges, reds, greens, blues—they aren’t just big show-offs either. Those colorful designs tell potential predators, „I’m toxic. Don’t eat me.“ Scientists think that poison dart frogs get their toxicity from some of the insects they eat. How do poison dart frogs capture their prey? Slurp! With a long, sticky tongue that darts out and zaps the unsuspecting bug! The frogs eat many kinds of small insects, including fruit flies, ants, termites, young crickets, and tiny beetles, which are the ones scientists think may be responsible for the frogs‘ toxicity. Poison dart frogs live in the rain forests of Central and South America.

Beavers are the largest rodents (gnawing animals) in North America and the second largest in the world, behind the South American capybara. Beavers are powerful swimmers that can swim underwater for up to 15 minutes. As the beaver dips underwater, the nose and ears shut to keep water out. Transparent inner eyelids also close over each eye to help the beaver see.

During the mating season, male blue-footed boobies strut around with exaggerated movements that show off their fabulous blue feet. Females tend to pick the males with the bluest feet as their mates. Parents take care of their chicks feeding and protecting them—until they’re about two months old. At that point, young boobies can survive on their own. Blue-footed boobies sleep at night, generally on land, and feed at sea during the day. Sometimes boobies feed in a group. They often fly far out to sea to look for their prey—small fish such as anchovies. The birds either zip underwater for fish from a floating position on the water’s surface or make awesome dives from as high as 80 feet (24 meters) in the air. Once it spots a school of fish, the bird folds those wings back, becoming a streamlined, torpedo-shaped predator. The booby dives into the water among the school of fish, using its long beak to grab dinner.

A tree stands in a forest under a cloudy sky. Suddenly it appears as if a twig is crawling down the trunk. The object isn’t actually a twig that’s sprung legs—it’s a stick insect. The stick-like trickster uses its appearance to protect itself from enemies so it doesn’t end up in, well, a sticky situation. FOOLED YA Stick insects—also known as walking sticks—live in tropical and temperate (or mild) forests all over the world. Related to grasshoppers, crickets, and mantises, these creepy-crawlies are usually brown, green, or black. They’re also the world’s longest insects. The largest one ever found stretched 22 inches with its legs extended. (Most are only up to 12 inches long.) This bug spends much of its time in trees, munching on leaves. When predators such as birds approach, the insect tries to remain completely still in order to blend with the branches. If a predator isn’t fooled and grabs the bug by the leg, it’s no big deal. The insect can detach the leg and scuttle away. It will later regenerate, or grow back, the lost limb. A GOOD EGG About 3,000 species of stick insects exist. Some are master mimics even before they hatch. The females from these species lay eggs that look like plant seeds. This prevents carnivorous insects from eating the eggs. This crawler really knows how to go undercover. Text by April Capochino Myers
