Happy Caturday! Meet the rusty-spotted cat. Known as the “hummingbird of cats,” it's one of the world’s smallest felines, weighing in at ~3.5 lbs (1.6 kg). Primarily nocturnal, this cat uses its large eyes to hunt under the cover of darkness.

The world’s most dangerous bird? It just might be the Cassowary. 😬 With dagger-like claws, it can leap 7ft (2m) to deliver a fatal kick. Weighing 130+ lbs (59 kg) and standing 6ft (1.8m) tall, this powerful bird is shy & can be found in Australia & New Guinea's rainforests.

It's time for Trilobite Tuesday! The Middle Cambrian trilobite Asaphiscus is among the most common of all North American species. Fossilized specimens, like this well-preserved 3-in- (7.6-cm) long example, can be found in tones ranging from red, to black, to brown, to purple.

Meet the Pinocchio anole. Thought extinct until a sighting in 2005, it inhabits parts of Ecuador. Growing ~3.3 in (8.4 cm) long, only males of this species sport long proboscises. Scientists think these fleshy appendages help them to attract mates.

👂Psst. Ever heard of the long-eared hedgehog? Inhabiting parts of Central Asia, this omnivore feeds on fruit, insects, & vertebrates like lizards. It has been observed rubbing its spines against toads, suggesting it might be using their toxins for its own self-defense.

Few compare to the Virginia opossum when it comes to “playing dead.” When threatened, it'll fall on its side, curl its body, & may supplement the act with open-mouth drooling & an excretion of feces in hopes of deterring hungry predators.

The Common Potoo is a master of disguise. You might think its huge yellow eyes would draw the attention of predators, but the bird has a workaround: It can close its peepers while staying aware of its surroundings, thanks to slits in its eyelids.

Ever seen a giant worm? 👀🪱 Members of the genus Martiodrilus can grow up to 4.9 ft (1.5 m) in length & weigh up to 1.1 lbs (0.5 kg)! Inhabiting parts of South America, these worms are rarely seen above ground—but can sometimes be heard as they move through the soil.

While it’s commonly called a “civet cat,” the Malay civet is actually more closely related to mongooses! This nocturnal critter hunts for small mammals, birds, and snakes—it also occasionally snacks on fruits and eggs.

What makes the swift fox so swift? It’s able to reach speeds of more than 30 mph, which comes in handy when hunting—or being hunted. The fox’s agility helps it snatch up prairie dogs and evade the jaws of hungry coyotes. It inhabits North America’s Great Plains.🦊

Have you ever seen the beautiful rainbow eucalyptus? When strips of its bark peel off, they change in color: Bark starts out in shades of green, then transitions into purple, red, & orange as time goes on. Continuous peeling helps the tree keep its trunk clear of other plants.🌈

You won’t spot the Pink-necked Green Pigeon on the streets of NYC! This colorful bird can be found throughout forests in Southeast Asia, where it forages mainly for fruit. Females of this species lack pink necks and are mostly olive-green in color.

No, you can’t pet that dog. Meet the bush dog! With partially webbed feet, this rare canid is a skilled swimmer and spends much of its time around water. It hunts for a variety of rodents including agoutis, pacas, and capybaras.
