African elephants have more genes dedicated to smell than anything else in the animal kingdom.
In a recent study published in Genome Research, scientists examining the number of genes associated with an animal's sense of smell found that an elephant's trunk was able to beat even the best known of nature's keenest noses including those of humans, horses, rats and even dogs.
With the biggest noses in the animal kingdom, of course elephants have the best sense of smell.
The biggest ears in the animal kingdom as well, but does that give it the best hearing in the world? It appears that prize would go to something smaller much than an elephants toenail.
Ultrasound simply refers to a sound that is outside a human's sonic range--which isn't that hard, really, as humans have modest auditory abilities. Researchers at the University of Strathclyde in Glasgow, Scotland have discovered that the greater wax moth (Galleria mellonella), a dull-colored, generally boring and common moth, has the most extreme hearing sense of any known animal. It's capable of hearing sounds frequencies of up to 300kHz, blowing away our piddly human abilities (at our best, humans can only hear up to about 20kHz). http://www.popsci.co...e-sense-hearing
