Animal Senses vs Human Senses

Through research I discovered that there are animals that have senses that by far exceed our five human senses. One of the animals would be the bat that we spoke about in class. Bats avoid obstacles and nab insects on the wing by emitting ultrasonic squeaks and interpreting the echo the sound waves make after bouncing off objects in the environment. This is called "echolocation," but bats aren’t the only animals that use echolocation. Dolphins also use echolocation to navigate themselves in murky water. Sharks were also discussed in class. Sharks have special cells in their brains that are sensitive to the electrical fields other creatures generate. This ability is so refined in some sharks that they can find fish hiding under sand by the weak electric signals their twitching muscles emit. They pick any electrical signal around them and even the weakest of electrical pulses give them a reason to investigate if its food or not. There are a few animals that we didn’t speak about in class that have senses that far exceed our own. For example Boa constrictors (large snake) have Temperature-sensitive organs located between the eyes and nostrils of boas and pit vipers allow the snakes to sense the body heat of their prey. There is one located on each side of the snakes' head, so the animals can perceive depth and attack with deadly accuracy even in complete darkness. Snakes in general also have another sense that is similar in a way to ours. Snakes have a forked tongue that is used to sniff its surroundings. Snakes use their tongues to collect particles wafting in the air. The coated tongue is then dipped into special pits in the roofs of the snake's mouth, called Jacobson's organs. There, the odors get processed and translated into electrical signals that are sent to the brain. Humans use their eyes to see their surroundings but the object in front of them is processed almost like our eyes take a picture and send the image to the brain they can recognize the...
