The frequency range of dog hearing is approximately 40 Hz to 60,000 Hz, which means that dogs can detect sounds far beyond the upper limit of the human auditory spectrum.

In Western Australia, the Indigenous Australians called these ants kallili or killal. [5] [better source needed] Ants of this genus are popularly known as bulldog ants, bull ants, or jack jumper ants due to their ferocity and the way they hang off their victims using their mandibles, and also due to the jumping behaviour displayed by some ...
Additionally, larger dogs have a better sense of smell than smaller dogs. [7] A dog's nose is significantly colder than their body temperature. This makes it more sensitive to thermal radiation. Dogs can thus detect even weak levels of warmth. [8] Dogs are able to smell from birth and develops during the first two weeks of their life.
Dogs can smell explosives like landmines, and detect medical conditions including seizures, diabetes, and many forms of cancer -- with up to 98% accuracy. Inventor Andreas Mershin wants to ...
Then, other ants follow suit, with more pheromones released, creating a more refined path. Which then attracts even more ants. Lather, rinse and repeat, and pretty soon an optimal path is forged ...
Ants and their larvae are eaten in different parts of the world. The eggs of two species of ants are used in Mexican escamoles. They are considered a form of insect caviar and can sell for as much as US$50 per kg going up to US$200 per kg (as of 2006) because they are seasonal and hard to find. [210]
Charles Darwin wrote of the interaction between size and complexity of invertebrate brains: . It is certain that there may be extraordinary activity with an extremely small absolute mass of nervous matter; thus the wonderfully diversified instincts, mental powers, and affections of ants are notorious, yet their cerebral ganglia are not so large as the quarter of a small pin's head.
The word myrmecology was coined by William Morton Wheeler (1865–1937), although human interest in the life of ants goes back to ancient times. The earliest scientific thinking based on observation of ant life was that of Auguste Forel (1848–1931), a Swiss psychologist who initially was interested in ideas of instinct, learning, and society.
