The green anaconda is the largest snake in the world, when both weight and length are considered. It can reach a length of 30 feet (9 meters) and weigh up to 550 pounds (227 kilograms). To picture how big that is, if about five ten-year-olds lie down head to foot, they’d be about the length of this huge snake. The green anaconda is a member of a family of snakes called constrictors. Constrictors are not venomous snakes. They don’t kill prey by delivering venom through a bite. Instead, constrictors wrap their bodies around their prey and squeeze until it stops breathing. The giant snake opens its mouth wide enough to swallow its victim—sometimes fish or caiman (relatives of crocodiles) and even jaguars and small deer. Anaconda jaws are held together with stretchy ligaments so they can open wide enough to swallow prey whole. And it’d take about 11 kids to weigh as much as one anaconda.

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.

Harp seals spend most of their time diving and swimming in the icy waters of the North Atlantic and Arctic Oceans. These sleek swimmers often hunt for fish and crustaceans at 300 feet (90 meters) and may dive to nearly 1,000 feet (300 meters). They are able to remain submerged for up to 15 minutes. During mating season, females form large colonies on floating ice and give birth to young. Older seals return annually to pack ice to molt. They lose their pelts and top layers of skin and grow a new fur coat every year. Harp seals are sometimes called saddleback seals because of the dark, saddlelike marking on the back and sides of their light yellow or gray bodies of the adults. Baby seals are born on pack ice floating in the North Atlantic and Arctic Oceans. Harp seal mothers are able to identify their babies by their smell. The pups don’t have any blubber at birth, but quickly gain weight nursing on high-fat mother’s milk. When the pups reach about 80 pounds (36 kilograms), their mothers stop nursing them. The pups go without food for about six weeks and can lose about half their body weight until they dive in and begin to hunt for themselves. The young seals are famous for their snowy white coats.
