humanity have five traditional senses : mouthful , touch sensation , hearing , olfactory property , and sight . Some animals have additional ways of perceive the environment beyond human capacity . While this list is not all inclusive by any mean , it is a small sample of some astonishing way to know the public .
Echolocation

echo sounding works by bid out to the environment and interpret the echo reception . The time it takes the echo to bounce back lets the animal judge length of other aim and animals .
Many animate being use this technique to navigate and find food , and some , like dolphin and bats , are not tight related . It was let on last month that echolocation is the intersection of convergent development . Instead of the trait being passed down from a plebeian ascendant , the same cistron mutated severally , resulting in the ability to echolocate .
It has been known for a while that unsighted humans can echolocate to navigate in the environment , but it is a skill thatsighted people can learnas well , accord to Modern research . It is likely that homo typically tune up out most echoes for hear human speech more clearly , but with training and learning how to pore , it is possible to be good at both .
Electroreception

The ability to sense electrical fields in the water is nearly exclusive to fish and amphibious animals because electrical energy is conducted better in water than in airwave . The power to smell the electric impulse from other animals is also good in areas when sight is limit , such as at night or in poor water quality .
Electroreception cultivate moderately like a shelling . When another animate being contracts its muscular tissue to move electrical impulses are generated . Those pulse jaunt out into the water where they will exchange electrons with sodium and chlorine ions . This interaction stabilizes the charge and makes it easy to be say by another creature .
While it is well known that sharks and several bony Pisces are up to of electroreception , it might be less known that mahimahi , duck - placard duckbill , and even bees utilize it to regain food . In the case of bees , a small electric field is give on a flower after it has been pollinated . This allows other bees to see which flowers are still usable , and which would be a barren of clip to visit .
Pressure detection

After discover that the beetles they were studying mated less when pelting was in the forecast , a team of researcher decide to study three unrelated metal money of insects to test their hypothesis that the insects were predicting the weather condition . Controlling for swooning , humidness , and temperature , the squad vary the pressure and find that insects wereless concerned in copulationas the pressure sensation dropped , as it does when rainwater is impendent . researcher think insects do this way to protect themselves from potentially life endanger rainfall , preferring to take cover rather of copulate .
Cobitidae is a syndicate of Pisces the Fishes commonly know as weather loaches . These Pisces respond to the alteration in air pressure by swimming unpredictably , as if they are face for a way to escape the environment .
Magnetoception

One of the most amazing animate being senses is the ability for many animals to rap into Earth ’s magnetized field fornavigation purposes . It was purpose late that this ability fall fromiron - rich crystalsin cells that move in response to the magnetics . In essence , these crystals might play like built - in range by add together pressure on these cells , point the animate being in the right guidance .
Many of the creature with the power to get directions from the Earth are migrant , such as sea turtleneck . However , invertebrates like yield flies , nudibranchs , and even certain bacteria are affected by magnetic pull .
