Some animals have developed
amazing adaptations to their
environments. Here are some examples of how some animals sense the outside world..!!
ANTS-- Can detect small movements through 5cm of earth. They can see polarized light..
BATS-- Can detect warmth of an animal from 16cm away. They can find food from upto 18ft using echolocation. They can hear sounds in betwenn frequency 3000hz to 120000hz..
BEES-- Can see lights between 300nm to 650nm. Worker honey bees have 5500 lences in their each eye. They also have a ring of iron oxide in their abdomen which they used to detect earths magnetic fields..
BUTTERFLY-- Has taste receptors in their feets. Have hairs in its wings which can detect air pressure variations..
CATS--Have hearing range of 100 to 60000hz. Olfactory membrane about 14 sq. cm. For comparison, humans have an olfactory membrane of about 4 sq. cm..
COCROACH-- Can detect movement as small as 2,000 times the diameter of a hydrogen atom..
CRAB-- Has hairs on claws and other parts of the body to detect water
current and vibration. Many crabs have their eyes on the end of stalks..
DOGS-- Has olfactory membrane up
to 150 sq. cm. Can hear sound as high as 40,000 Hz..
EARTH WORMS-- Entire body is covered with taste receptors..
ELEPHENTS-- Has hearing range
between 1 and 20,000 Hz. The very
low frequency sounds are in the
"infrasound" range. Humans cannot hear sounds in the infrasound range..
FALCON-- Can see a 10cm object from 1.5km. Can see sharp images even when diving at 100 miles/hr..
FLY-- Each eye has 3,000 lenses. Blowflies taste with 3,000 sensory hairs on their feet..
GRASS HOPPER-- Has hairs ("sensilla") all over the body to detect air movement. Can hear up to 50,000Hz..
MOSQUITO-- Attracted to host by human body odor (especially foot
odor), carbon dioxide, body heat and body humidity..
SCORPION-- Can detect air moving at only 0.072km/hr with special hairs on its pincers. Can have as many as
12 eyes..
