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.

Coyotes are adaptable predators living in cities and wild areas. Learn about their intelligence, howling communication, and survival skills.
Coyotes are highly intelligent and adaptable canines that have expanded their range across North America despite human efforts to eliminate them. Unlike most predators, coyote populations have actually increased over the past century, and they now thrive in major cities alongside millions of people.
Coyotes live in nearly every major North American city including New York, Los Angeles, and Chicago. They adapt to urban life by hunting at night, using drainage systems as highways, and learning traffic patterns. Urban coyotes eat rats, rabbits, fruit, and garbage while avoiding human contact. Some city coyotes become so specialized they never leave urban areas their entire lives.
Coyote howls serve multiple purposes beyond the haunting sound they create. Each coyote has a unique howl that identifies them to pack members. Howling coordinates group hunts, warns other packs to stay away, and helps separated family members reunite. Coyotes can hear these howls from up to 3 miles away. They often howl just after sunset and before dawn.
Coyotes possess a remarkable ability to increase reproduction when their population declines. When coyote numbers drop, females have larger litters of 5 to 7 pups instead of the usual 3 to 4. More females also breed, and pups mature faster. This biological response means that culling programs often backfire, causing coyote populations to bounce back even stronger.
Coyotes are clever hunters that adapt their tactics to available prey. They hunt alone for small prey like mice but form packs to take down deer. Some coyotes team up with badgers, with coyotes chasing ground squirrels above ground while badgers dig them out below. Urban coyotes learn to use crosswalks and time their movements to avoid rush hour traffic.
Coyotes are opportunistic omnivores that eat whatever food is available. Their diet includes rabbits, rodents, deer, birds, fish, insects, fruit, and vegetables. In cities, they consume pet food, garbage, and fallen fruit from trees. This dietary flexibility allows coyotes to survive in diverse environments from deserts to frozen tundra to downtown streets.
Coyotes can run 43 mph in short bursts and maintain 25 to 30 mph for longer distances while chasing prey. They can jump 8 foot fences, swim across rivers, and dig under barriers. Their agility and endurance make them effective hunters. Coyotes have excellent night vision and can hear a mouse moving under snow from 300 feet away.
Coyotes figure prominently in Native American mythology as tricksters who shaped the world.
European settlers began systematic coyote eradication in the 1850s that continues today.
The U.S. government has spent billions of dollars trying to eliminate coyotes without success.
Coyotes originally lived only in prairies and deserts but have expanded to every ecosystem.
Research found coyote packs increase reproduction rates when their numbers are reduced, compensating for losses.
Studies showed urban coyotes have larger territories and hunt more at night to avoid humans.
Scientists documented coyotes using traffic patterns to cross busy roads safely.
Genetic analysis revealed eastern coywolves carry wolf, coyote, and dog DNA.
The coyote trickster remains central to Native American storytelling and spirituality.
Wile E. Coyote cartoons shaped public perception of coyotes as persistent if unsuccessful predators.
Urban coyote sightings regularly make news, generating both fascination and fear.
Coyote howls have become the soundtrack of both wilderness and suburban nights.
Before European settlement, coyotes lived primarily in the prairies and deserts of central North America. Wolves dominated the forests and kept coyotes confined to open country. Coyotes were one predator among many in the ecosystem.
Wolf extermination opened the continent to coyotes. Despite over 500,000 coyotes killed annually in the U.S., they now occupy every state, every ecosystem, and every major city. They hybridized with wolves to colonize eastern forests and adapted to hunt in urban parks and parking lots. The animal humans tried hardest to eliminate has become the most successful wild predator in North America.

How much do you know? Take this quick quiz to find out!
Coyotes are one of the few animals whose range has expanded rather than contracted due to human activity.
When coyote populations are reduced, females have larger litters and more pups survive, quickly replacing losses.
Coyotes have been documented looking both ways before crossing streets in urban areas.
A coyote can run at 40 mph and leap 14 feet in a single bound.
Coyote pairs often mate for life and raise pups together for years.
Eastern coywolves can weigh twice as much as western coyotes due to their wolf ancestry.
Coyote attacks on humans are extremely rare. Coyotes naturally fear humans and usually run away when encountered. Most incidents involve coyotes that have been fed by people and lost their natural wariness. Never feed coyotes, and make loud noises if one approaches to reinforce their fear.
