Crab Facts: Claws, Shells & Secret Behaviors
Crabs are crustaceans found on every continent with over 7,000 species. Discover why crabs walk sideways, trade shells, and grow claws stronger than jaws.

Raccoons are intelligent, adaptable mammals known for their distinctive facial masks and dexterous paws. They thrive in diverse habitats including cities.
Raccoons are highly intelligent and adaptable mammals famous for their distinctive black facial masks and ringed tails. These clever animals possess remarkable problem solving abilities and dexterous paws that function almost like human hands.
Their bushy tails display 4 to 10 alternating black and light colored rings. Raccoons possess highly sensitive front paws with five toes that manipulate objects with surprising precision. Raccoons can rotate their hind feet 180 degrees, allowing them to climb down trees headfirst.
Raccoons demonstrate intelligence comparable to primates in many tests. Research shows raccoons can remember solutions to problems for at least three years. One study found raccoons could pick locks in fewer than 10 attempts.
Raccoons eat almost anything edible, making them true omnivores. Their natural diet includes fruits, nuts, berries, insects, frogs, crayfish, eggs, and small mammals. They excel at catching fish and crayfish from streams using their sensitive paws to feel under rocks and in crevices.
Raccoons are primarily nocturnal, conducting most activities at night. Their excellent night vision and sensitive whiskers help navigate darkness. A typical night involves traveling 1 to 2 miles searching for food.
Raccoons were once thought to be solitary, but research reveals more complex social structures. Related females often share territories and sometimes den together. Raccoons communicate through over 200 different sounds including purring, chittering, growling, hissing, and screaming.
Raccoon breeding season occurs from January to June depending on latitude. After a 63 day gestation period, females give birth to litters of 3 to 5 kits. Kits remain in the den for 8 to 10 weeks before venturing outside.
Native Americans used raccoon fur for clothing and featured raccoons in folklore as clever trickster figures.
European colonizers named them from the Algonquian word arahkun meaning he scratches with his hands.
Raccoon fur became valuable in the 1700s and 1800s, driving extensive trapping throughout North America.
The coonskin cap became an American cultural symbol, popularized by Davy Crockett and frontier mythology.
Raccoons expanded their range dramatically in the 1900s, adapting to human environments and spreading into new territories.
Studies revealed raccoons can pick complex locks in fewer than 10 attempts, demonstrating advanced problem solving.
Research showed urban raccoons are measurably smarter than rural ones, having adapted to human challenges.
Scientists discovered raccoons have five times more touch receptors in their paws than most mammals.
Studies documented over 200 distinct vocalizations used for communication between raccoons.
Research proved raccoons can rotate their hind feet 180 degrees to climb down trees headfirst.
Raccoons became icons of urban wildlife, representing adaptation to human environments worldwide.
Trash panda became an affectionate internet nickname, spawning countless memes and viral content.
Raccoons in Japanese culture inspired the tanuki folklore figure and anime characters.
Wildlife control industries grew around managing raccoon human conflicts in cities.
Conservation discussions now include raccoons as examples of successful urban wildlife adaptation.
Before widespread urbanization, raccoons lived primarily in forests near water sources, eating natural foods like crayfish, frogs, and berries. Their populations were limited by available habitat and controlled by natural predators. Raccoons rarely encountered humans except in rural farming areas.
After cities expanded, raccoons adapted brilliantly to urban environments. They learned to open garbage cans, raid pet food, and den in attics and chimneys. Urban raccoon populations now exceed forest densities in many areas. Their intelligence, which once helped them survive in wilderness, now makes them successful urban wildlife that challenges human attempts to exclude them.

They do not actually wash food. Dousing enhances touch sensitivity in their remarkably sensitive paws.
Urban raccoons are smarter. City raccoons show more advanced problem solving than rural ones.
Their scientific name means washer. Procyon lotor translates to before dog washer in Latin.
They cannot be good pets. Despite intelligence, raccoons become aggressive at maturity and remain wild.
Raccoons have hands, not paws. Five dexterous fingers manipulate objects almost like human hands.
They remember for years. Solutions to problems stay in raccoon memory for at least three years.
Raccoons are highly intelligent animals with problem solving abilities comparable to primates. They can remember solutions to problems for at least three years, learn to open complex latches, pick locks in fewer than 10 attempts, and solve multi step puzzles. Urban raccoons show even more advanced intelligence than rural ones, demonstrating their learning capabilities.
