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.

Zebras are striped equines with 3 species in Africa. Discover why zebras have stripes, their social behaviors, habitats, and their important roles in grassland ecosystems.
Zebras are African equines famous for their distinctive black and white striped coats. Three species exist: plains zebras, mountain zebras, and Grevy's zebras.
Every zebra has a completely unique stripe pattern. No two zebras share identical stripes. Foals recognize their mothers by memorizing stripe patterns, scent, and voice. Scientists use stripe patterns to identify individual zebras in field studies.
Zebras have stocky bodies with relatively short legs compared to horses. Their powerful neck muscles support large heads. Zebras have excellent senses. They can run up to 40 mph and maintain steady speeds for long distances when escaping predators.
Zebra social structures vary by species. Plains zebras form stable family groups led by a dominant stallion with several mares and their offspring. These harems contain 5 to 20 individuals. Family groups remain together for years.
Zebras are herbivores that primarily eat grasses. They are less selective grazers than other herbivores and consume coarser, tougher grasses that many animals avoid. They may travel over 10 miles to water sources during dry seasons. They spend 60 to 80 percent of their time feeding, especially during dry seasons when grass quality decreases.
Zebras breed year round, though most births occur during rainy seasons when grass is abundant. After a gestation period of 12 to 13 months, mares give birth to single foals. Newborns weigh 55 to 88 pounds and can stand within minutes of birth. Young zebras reach independence at 1 to 2 years but females often remain with their birth herd.
Zebras have existed in Africa for over 4 million years, evolving alongside human ancestors.
Ancient Romans captured zebras for arena spectacles, calling them tiger horses.
European colonizers attempted unsuccessfully to domesticate zebras for transport in Africa.
Walter Rothschild famously drove a carriage pulled by zebras through London in the early 1900s.
Quagga zebras went extinct in 1883, with efforts now underway to breed back similar animals.
Research confirmed zebras are black with white stripes based on embryological development.
Studies showed each zebra's stripe pattern is unique like human fingerprints.
Scientists discovered stripes deter biting flies, which avoid landing on striped patterns.
Research revealed foals imprint on their mother's specific stripe pattern for recognition.
Studies confirmed zebras cannot be domesticated due to temperament, not intelligence.
Zebra crossings got their name from the striped pattern used on pedestrian crosswalks.
Zebras symbolize Africa in global consciousness and tourism marketing.
The unique stripe patterns make zebras instantly recognizable worldwide.
Conservation of Grevy's zebras became a flagship effort for endangered African wildlife.
Zebra patterns influenced fashion, design, and art for centuries.
Before human population growth in Africa, zebras roamed in vast herds across the continent. Quagga zebras were abundant in South Africa. Zebras maintained healthy population dynamics with natural predators. Migration routes remained unobstructed across grasslands.
After livestock competition, habitat loss, and hunting increased, zebra populations declined significantly. Quagga zebras went extinct in 1883. Grevy's zebras fell to fewer than 3,000 individuals. Conservation efforts now protect remaining populations, though challenges from drought and habitat fragmentation continue.
No two zebras have exactly the same stripe pattern, like human fingerprints
Zebra foals can recognize their mothers by unique stripe patterns, scent, and voice
A group of zebras is called a dazzle or a zeal
Zebras can sleep standing up but only enter deep sleep when lying down near family
Grevy's zebras have the narrowest stripes and largest ears of all zebra species
Zebras have never been successfully domesticated unlike horses and donkeys
Grevy's zebras are endangered with fewer than 3,000 remaining in the wild
Habitat loss from livestock grazing reduces food availability for wild zebras
Climate change increases drought frequency, threatening zebra water sources
Zebra watching tourism supports conservation and local economies in Africa
Research on zebra stripes continues revealing surprising functions
How much do you know? Take this quick quiz to find out!
They are black with white stripes. Embryos are entirely black before white develops.
Stripes deter biting flies. Research showed flies avoid landing on striped patterns.
Never successfully domesticated. Zebras are too aggressive and unpredictable unlike horses.
No two patterns match. Stripe patterns are unique like human fingerprints.
Foals memorize mother's stripes. Baby zebras imprint on specific patterns for recognition.
A group is called a dazzle. The collective noun reflects their confusing stripe effect.
Scientists believe zebra stripes serve multiple purposes. Stripes may confuse predators when zebras flee in groups, creating a motion dazzle effect. Research shows stripes deter biting flies, which avoid landing on striped patterns. Stripes might also help regulate temperature by creating cooling air currents. Each zebra's unique stripe pattern helps foals recognize their mothers.
