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.
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.
Megaponera is a genus of ponerine ant first defined by Gustav Mayr in 1862 for the species Formica analis Latreille, 1802, [8] the sole species belonging to the genus to date. . In 1994 William L. Brown Jr. synonymised the genus under Pachycondyla even though he lacked phylogenetic justification, thereby changing the name from Megaponera foetens to Pachycondyla analis.
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 ...

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.
