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. [3] n/a may be up to 100 million times greater than a human. n/a n/a n/a n/a n/a Human: red~650 nm to violet ~400 nm (or) VIBGYOR: 20 Hz to 20,000 Hz (or) Audio: n/a n/a n/a n ...
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 ...
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.
[4] [2] Finally, it has been suggested that this is a type of olfactory camouflage, meaning the smell of the ants would mask that of the insect, however, this theory has not been studied. [ 4 ] What is known is that masked bugs get preyed upon much less than naked bugs by visually oriented predators, leading to the conclusion that the ...
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 ...
This mechanism permits the ants to accumulate energy before striking or releasing the mandibles rapidly. O. bauri is known for its powerful mandibles, which can open up to about 180° and within 10 ms of being stimulated and can close within 0.5 ms, [2] which help with catching prey. The mandibles are able to sting and paralyze prey or crush ...
