Animal senses

Every animal on the planet has adapted to survive in their environment. From the frigid arctic to the world jungles each species evolved their senses to live in their area. Some of these adaptations are quiet unique and surprising.

Ants have the ability to feel movement as far as two-and-one-half inches away and they can also see concentrated light. Bees have 5,500 lenses in every eye and worker bees have a magnetic detector for navigation. Butterflies can see two points as close together as thirty microns or one millionth of a meter. A cockroach can feel movement as little as 2,000 times the diameter of a hydrogen atom.

Bats use echolocation to find their way and capture their prey, They have a flap of skin on their noses called a “nose leaf” that can feel the warmth of the animals they hunt more than six inches away. Cats have acute hearing. Dogs can smell odors as far as 185 feet.

Chameleons have independent eye sockets. Iguanas can feel temperature of sand within two degrees so they know when to lay their eggs. Snakes use their tongues to accumulate odors and transfer them to the smell and taste pits in their mouth known as “Jacobson’s organs.”

Jellyfish have twenty-four eyes. Octopi have taste receptors on their tentacles. The arms of a starfish are covered with light sensors. Most fish have a sense organ to feel water pressure.

Buzzards can see a rodent from 15,000 feet in the air. Hawks can see four times as far as humans. Penguins have flat cornea to see clearly underwater. Pigeons can feel very low sounds. Sparrows have 400,000 receptors in their retina.

Milwaukee area residents can visit the Milwaukee County Zoo to observe these adaptions.
