Jellyfish have drifted along on ocean currents for millions of years, even before dinosaurs lived on the Earth. The jellylike creatures pulse along on ocean currents and are abundant in cold and warm ocean water, in deep water, and along coastlines. But despite their name, jellyfish aren’t actually fish—they’re invertebrates, or animals with no backbones. Jellyfish have tiny stinging cells in their tentacles to stun or paralyze their prey before they eat them. Inside their bell-shaped body is an opening that is its mouth. They eat and discard waste from this opening. As jellyfish squirt water from their mouths they are propelled forward. Tentacles hang down from the smooth baglike body and sting their prey. Jellyfish stings can be painful to humans and sometimes very dangerous. But jellyfish don’t purposely attack humans. Most stings occur when people accidentally touch a jellyfish, but if the sting is from a dangerous species, it can be deadly. Jellyfish digest their food very quickly. They wouldn’t be able to float if they had to carry a large, undigested meal around. They dine on fish, shrimp, crabs and tiny plants. Sea turtles relish the taste of jellyfish. Some jellyfish are clear, but others are in vibrant colors such as pink, yellow, blue, and purple, and often are luminescent. The Chinese have fished jellyfish for 1,700 years. They are considered a delicacy and are used in Chinese medicine.

Crossing a beach to get to the sea, a two-foot-tall Humboldt penguin waddles over what appears to be a cluster of large boulders. Suddenly one of the rock-like objects rises up and barks! The penguin is stepping on sea lions lounging on the shore. Sea lions prey on Humboldt penguins in water but are too slow to catch them on land. The bird continues to ruffle feathers as it climbs over more annoyed sea lions. But it finally makes it to the ocean and dives in for a swim. A GOOD SPORT Humboldt penguins live along the shores of Peru and Chile, two countries in South America. Named for a chilly water current that flows through their coastal range, these birds are excellent swimmers. Their torpedo-shaped bodies can shoot through the water at speeds of 30 miles an hour. And they can dive up to 500 feet underwater in search of snacks such as fish, shrimp, and squid. When the birds need a break from swimming, they come ashore. Getting around on land isn’t always easy. Parts of their habitat feature rocky seaside cliffs. Luckily the animals have some built-in climbing gear: They use sharp claws on their webbed feet to grip onto rocks as they move across the rugged landscape. The animals also put their climbing skills to use when they have to scramble over sunbathing sea lions blocking their path to the ocean. THINK PINK During the hottest months of the year, temperatures in the Humboldt penguin’s home can reach triple digits. The animal has ways to beat the heat though. It sports patches of bare, pink skin around its eyes and at the base of its bill. The bird expels body heat through these featherless spots. This little guy’s athletic abilities and its pink patches make it one colorful penguin! Check out the book Penguins vs. Puffins for more about these amazing birds!
