It’s Fossil Friday! Unlike its three-horned cousin Triceratops, Styracosaurus had a singular nasal horn & huge spikes on its frill. It may have used its headgear to defend against predators, attract mates, or compete with rivals.
A photo of Styracosaurus on display in the Museum. It is brown in color, with a parrot-like beak, large nasal horn, and spiky frill.

The Resplendent Quetzal inhabits the cloud forests of Central America at elevations of up to 10,00 ft (3,048 m). Males showcase brilliant iridescent green plumage that contrasts with a vibrant shock of red on their bellies, and their tail feathers can grow ~3 ft (0.9 m) long!

The Grandidier's baobab, also known as the renala, may live to be more than 300 years old! Scientists are unable to confirm these trees' exact age because baobabs don't produce annual growth rings. This species of baobab is found only in Madagascar's dry deciduous forests.

The world’s largest terrestrial invertebrate? That would be the coconut crab. It can span ~3 ft (1 m) long from leg tip to leg tip & weigh ~8 lbs (4 kg)! It inhabits coasts off of the Indo-Pacific Ocean. Scientists have compared its pinching power to a lion’s bite force!🥥🦀

What’s a spiny lumpsucker? No, it’s not a nickname for your ex. This fish's body shape and small fins mean that it isn’t the best swimmer, but a powerful pelvic fin helps it stick to solid surfaces, acting like a suction cup to hold it in place as it hides from predators.
A photo of a spiny lumpsucker directly facing the viewer. It is pale gray in color and round in shape, with a bumpy texture covering its body.

Few things make it feel more like fall than the foliage of the red maple tree. #DYK? It sports something red all year round: in winter, it has red buds; in spring, red flowers begin to bloom; in summer, the leaf stalks turn red; & in autumn, the foliage is a vivid orange-red.🍁
A photo of many red maple leaves arranged artfully on a tree stump. The leaves vary in color from greenish to yellow to deep red.

#DYK? The short beaked echidna is a monotreme, meaning it’s one of the few mammals that lays eggs instead of bearing live young. And? This species is unusually long-lived, with individuals living up to 50 years in captivity. This spiky critter can weigh ~15.4 lbs (7 kg).

This cricket isn’t named Jiminy. Growing ~1.9 in (5 cm) long, the armored bush cricket uses powerful jaws to feed on a diet that includes leaves, other crickets, & even nestling birds. When threatened, it's able to squirt a distasteful liquid called hemolymph at foes.

What’s up? Not the ground pangolin. It spends most of its time on the ground, creating underground burrows to snooze in during daylight. At night, it uses its long tongue to slurp up insects. When threatened, it can roll up into a ball, protecting its soft body from predators.
A photo of a ground pangolin. The animal has a small head and slightly elongated snout. Its body is covered in pinecone-like scales. It has clawed feet.

Who’s this fuzzy noodle? That would be the long-tailed weasel. North America’s largest weasel, this nocturnal critter feeds on small mammals, insects, and birds. It inhabits the burrows of other species, but it’s also a skilled climber that can often be found in the trees.

Meet the gold-mouth sea squirt! This filter-feeder draws in water through an opening known as a siphon to devour phytoplankton and bacteria. It can be found in waters off of Southeast Asia and Australia.

Why does the binturong smell like buttered popcorn The answer is... pee! A chemical compound-2-acetyl-1-pyrroline-in this critter's urine is the same one found in popcorn. It uses its signature scent to mark its territory and attract mates.
A photo of the binturong. It is primarily black in color, with a gray face and long whiskers, and resembles both a cat and a bear. Its mouth is slightly open.

The little pygmy possum is the smallest possum in the world. This marsupial typically weighs only 0.4 oz (10 g)—about the weight of 10 almonds. This omnivore has a taste for the nectar & pollen of flowering plants, and it can consume up to 7% of its body weight in a single day!
A photo of a little pygmy gray possum held in a human hand. The animal is tiny and gray in color, with pink hands and feet. It is about the size of a human thumb.

#OTD in 1914, Martha (the last-known living Passenger Pigeon) died at the Cincinnati Zoo. Her death—at 29 after a lifetime in captivity—marked the disappearance of her once-abundant species from the world & made her name synonymous with species extinction at human hands.

What color is the Australian King Parrot? 👀 If you answered red and green, you’re only partially right! Under UV light, some of its plumage has a distinctly golden hue, which is invisible to the human eye. How can you tell males and females apart? Males have red heads.

Ever heard of the aardwolf? It’s an insectivorous mammal that’s in the same family as the hyena. Unlike its carnivorous relatives, it’s one of a few mammals that feed exclusively on termites. In summertime, it can gobble up ~200,000 termites for its midnight meal!

Meet the giant rain frog! To survive the summer heat, this amphibian burrows underground. At about 1.8 in (4.5cm) long, it’s the largest of all rain frogs. When threatened, it can blow up like a balloon, intimidating foes with sudden roundness.
A photo of a giant rain frog held in a human hand. The frog is bloated and round. It has a pale underbelly and a brown, speckled back.

Have you ever seen a “bleeding” fungus? When the devil’s tooth is moist, it oozes striking droplets of red liquid. But this only happens when the fungus is young—as it grows, it turns brownish & stops secreting fluid. Believe it or not, this “bleeding” mushroom is not toxic!

This critter can spend up to 23 hours a day looking for food! Meet the Eastern mole. This dirt puppy weighs 4.9 oz (140 g)—about the weight of about two C batteries. With poor eyesight, it spends most of its life underground hunting for worms and other insects.

This archival image, snapped sometime before 1960, depicts duck-billed dinosaurs on display at the Museum. Also known as hadrosaurs, these massive herbivores were the dominant plant-eaters during the Late Cretaceous ~85 million years ago.
