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.

Bats are the only mammals capable of true flight. Learn about bat echolocation, diet, species, habitats, and their vital role in ecosystems.
Bats are the only mammals capable of true sustained flight. With over 1,400 species worldwide, bats represent approximately 20% of all mammal species on Earth.
Most bat species use echolocation to navigate and hunt in complete darkness. Bats emit high frequency sounds between 20 and 120 kHz through their mouth or nose. Some species can detect prey up to 165 feet away using this system.
Bat wings are actually modified hands with elongated fingers covered by a thin membrane called the patagium. This flexible wing structure allows bats exceptional maneuverability in flight. The Mexican free tailed bat can reach speeds exceeding 100 mph, making it one of the fastest flying animals.
Most bats are insectivores that consume vast quantities of insects. A single bat can eat up to 1,200 mosquitoes in one hour. Only three bat species feed on blood, and they primarily target livestock rather than humans.
Bats live on every continent except Antarctica. They roost in caves, trees, buildings, and other sheltered locations. Most species are nocturnal and emerge at dusk to hunt.
Female bats typically have a gestation period of 40 days to six months depending on the species. Many species live 10 to 20 years in the wild. Some individuals have been documented living over 30 years.
Bats provide essential ecosystem services valued at billions of dollars annually. Insect eating bats reduce agricultural pests, decreasing the need for pesticides. Fruit and nectar bats pollinate over 500 plant species including economically important crops.
Bats evolved flight around 55 million years ago, developing echolocation independently from any other mammal group.
Ancient cultures held varied beliefs about bats, from Chinese symbols of good fortune to European associations with darkness.
Bat guano was so valuable for gunpowder production that caves were protected military resources during the American Civil War.
Scientists studied bat echolocation to develop sonar and ultrasound technology used in medicine and navigation.
Research proved bats are more closely related to humans than to rodents, sharing a common ancestor with primates.
Studies revealed some bat species can live over 40 years despite their small size, defying normal mammal lifespan patterns.
Scientists discovered bat immune systems can host viruses without getting sick, making them important for disease research.
Acoustic research showed bats can adjust their echolocation frequency to avoid jamming each other in crowded caves.
Vampire mythology drew heavily from vampire bat behavior discovered when Europeans reached the Americas.
Batman became one of the most iconic characters in popular culture, reshaping bat imagery for generations.
Bat festivals in Austin, Texas attract hundreds of thousands of visitors to watch 1.5 million bats emerge at dusk.
Conservation campaigns now emphasize bats as essential pollinators and pest controllers rather than scary creatures.
Before scientific understanding improved, bats were feared and persecuted across Western cultures. People associated them with vampires, disease, and evil. Colonies were destroyed, caves were sealed, and bats were killed on sight in many communities.
Modern research transformed bat perception from pest to essential ecosystem partner. We now understand bats save billions in agricultural pest control, pollinate crucial crops, and may hold keys to disease immunity and longevity research. Conservation efforts protect major colonies, and bat watching has become popular ecotourism.

Bats are not blind. Most species can see as well as humans, and fruit bats have excellent color vision.
Vampire bats are the only mammals that survive entirely on blood, but they also share food with hungry roostmates.
Some bats can eat up to 150% of their body weight in insects in a single night.
Bat wings contain the same bones as human hands, stretched with a thin membrane between elongated fingers.
Mexican free tailed bats can fly at over 100 mph, making them the fastest horizontal flying animals on Earth.
Bats always turn left when exiting a cave, a behavior scientists still do not fully understand.
No, bats are not blind. All bat species can see, and many have excellent vision, especially in low light conditions. While they rely heavily on echolocation for navigation and hunting, their eyes are fully functional and help them navigate during dusk and dawn.
