Dogs are dichromat and less sensitive to differences in grey shades than humans and also can detect brightness at about half the accuracy of humans. [2] 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
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.
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.
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 ...
Commonly known as trap-jaw ants, species in Odontomachus have a pair of large, straight mandibles capable of opening 180°. These jaws are locked in place by an internal mechanism, and can snap shut on prey or objects when sensory hairs on the inside of the mandibles are touched. The mandibles are powerful and fast, giving the ant its common name.
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 ...
[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 ...
THE BOTTOM LINE: I think Spotify’s algorithm is better at predicting what I want to hear while also bringing me back to throwbacks I loved in the past. In my opinion, Spotify’s taste profile ...
