Dolphins




Some people claim that dolphins and whales communicate in such a way that it is very
similar to human speech. An analysis will be coucted to determine if there is more similarity or
difference between these animals and humans.
Dolphins are aquatic mammals closely related to whales. They aresleek and powerful
swimers. They can be found in all seas around the world. It is interesting to point out that they
spend about 99% of their time on the water. This affects their consiouness. It means that they have
strong feelings and wiilpower.
These animals have the ability of swimming at speeds of up to 30 km per hour. Their lungs
are adapted to resist the physical problems created by rapid changes in preassure. another
characteristic of dolphins is that they eat an amount of food , mostly fish and squid, equevalent to
nearly one third of their weight. Dolphins can learn and remember things, wether the information
arrives throuh their ears or eyes. They can also distinguish different items and understand a visually
based sign language.
They see well both under water and in air. Howevwer, dolphins vision is better at distances
greather than one meter. In water their vision is best at distances of less than a meter. Neverless,
they don\'t seened to posses true color vision.
Dolphins can produce a wide variety of sounds incliding clicking and whistles. They
communicate with each other under water, and their sounds in the air are attemps to speak with
people. They also sed out calls and warning signals. It represents a behavior similar to the human
beings.
In the animal kingdom, dolphins are the best users and perceivers of sound. They are able
to recognize different melodies and sounds. Their vocalization is produced by forcing air back an
forth between air sacs inside their bodies. Without this communication and interdependence they
would have dissapeared from the planet, having joined the dinosaurs as an extinct specie, among
others.
The voice of the dolphins in air is like the humans. They can pronounce vowels, but have
difficulties with consonants. This situation means that they havea voice that sometimes could be
perceived as a human voice. Dolphins know that certains gestures and sounds symbolize a particular
command, and they always want to understand it. These animals have a brain larger than a human.
Several studies have shown that dolphins have an intelligence that is very competitive versus human.
