A small frog the length of a quarter leaps from one plant leaf to another, flaunting its little belly as it soars. The skin on the frog’s underside is see-through. So as the amphibian jumps you can view some of its internal organs, including its beating heart. This is a reticulated glass frog, a creature that has a lot of supercool secrets to reveal. DADDY DAY CARE Reticulated glass frogs can be found in the rain forests of Costa Rica, Panama, Colombia, and Ecuador. These animals, which are active at night, inhabit vegetation along streams. Males can get pretty territorial, making squeaking noises to warn trespassing frogs to stay away from their leafy hangout spots. If an intruder doesn’t leave, the frog will wrestle it to show who’s boss. Males are also very protective of their mates’ eggs. Females lay a mass of eggs (called a clutch) on the underside of leaves, sticking them in place with a jelly-like substance. Afterward, the females leave and the males go on guard duty. They watch the eggs 24/7 until they hatch, protecting them from enemies such as wasps. The frog has even been known to kick away wasps that get too close to the egg cluster! TRICK EGGS Scientists still aren’t sure why these frogs have see-through skin on their undersides. But they think the spotted pattern on the backs of the amphibians is meant to resemble a mass of eggs. This camouflage pattern helps the males protect their offspring by confusing predators trying to get at the clutch. Sounds like these eggs are in good webbed hands! Text by Andrea Silen, NGS Staff

A rainbow-colored crustacean skitters along the ocean floor, adding a splash of brightness to the murky setting. The animal’s narrow, hard-shelled body sports orange, green, red, and blue hues. Known as the peacock mantis shrimp, this beautiful, seven-inch-long critter looks harmless. But the marine animal packs a punch—literally. SHRIMP SMACKDOWN Peacock mantis shrimp mostly live in shallow parts of the Indian and Pacific Oceans. The crustacean spends much of its time looking for crabs and mollusks to eat. When it finds a delicious-looking snack, the animal goes into full-on boxer mode. Springing out one of its club-like front claws, the animal delivers a swift punch to its prey. The punch is 50 times faster than the blink of an eye and strong enough to break glass! These shrimp also rely on their sparing moves to keep enemies away from burrows in the ocean floor that they use as shelters. Hovering at the opening of its burrow, a peacock mantis shrimp will strike at intruders that come too close. EYES ON THE PRIZE The crustacean has another eye-popping feature in addition to its strong punch. Its eyes—which protrude from its head and move independently—can see in two different directions at once. They can also detect colors that humans are unable to see. It’s easy to be floored by this animal’s cool traits! Watch a video of the peacock mantis shrimp. Text by Andrea Silen, NGS Staff
