Bats use echolocation to navigate and hunt in the dark. They emit high-frequency sound waves that bounce off objects, allowing them to 'see' their surroundings through sound. Owls have excellent vision but do not use sonar.

Humans are warm-blooded (endothermic) animals, meaning we maintain a nearly constant internal body temperature regardless of the environmental temperature. Cold-blooded animals (ectotherms) rely on external heat sources.

Humans are classified as mammals because they possess mammary glands (which produce milk for offspring), have hair or fur, and are warm-blooded vertebrates. This is a fundamental biological classification.

Coprophagy refers to the consumption of feces. Many animals, such as rabbits and various insects, engage in this behavior to recover nutrients that were not fully absorbed during the first passage through the digestive tract.

Aristotle is traditionally known as the 'Father of Zoology' due to his extensive observations of animals and his attempts to classify them based on their characteristics and habitats in works like 'History of Animals'.

Mary Anderson was granted the first patent for an automatic car window cleaning device (windshield wipers) in 1903. The question uses 'Windshield' as shorthand for the wiper system. Marie Curie and Katherine Blodgett worked in physics and chemistry.

Patricia Billings, a sculptor, invented Geobond, a non-toxic, fireproof building material, while trying to find a durable plaster for her art. Valerie Thomas and Bette Nesmith Graham are famous for unrelated inventions.

Katherine Blodgett was the first woman to earn a PhD in physics from Cambridge and invented 'invisible' or non-reflecting glass by adding monomolecular film coatings to surfaces. This technology is essential for cameras and eyeglasses.

Marie Curie is renowned for her pioneering research on radioactivity and her development of mobile X-ray units during WWI. While Wilhelm Röntgen discovered X-rays, Curie's work was fundamental to the technology's medical application.

Sally Fox is an inventor and breeder who developed 'FoxFibre,' the first commercially viable naturally colored cotton that could be spun by machines. Hedy Lamarr co-invented frequency hopping, and Ruth Handler created the Barbie doll.
