Dolphins and humans, how much we know?

Dolphins, are the cousins to whales as they resembles themselves, member of the family Delphinidae, and an animal that captures the heart of anyone who sees one. This powerhouse of a marine mammal can swim at speeds of up to thirty-five miles per hour and renowned for the fact that they can jump out of the water, a feat meant to both conserve energy and to get places quicker. When they swim, they are as graceful as a swan and as playful as a little child. Well, read on to find out more about these amazing creatures. When you see a dolphin, you are in awe, but what sort of questions do you ask? How do they swim so fast, what do they eat, where do they live? First, the anatomy of a dolphin. We’ll start with a dolphin’s teeth. Dolphins have eighty to one-hundred cone-shaped teeth. These teeth are set up in a position to interlock and hold slippery fish in its mouth. Because the teeth interlock like that, and the teeth are as sharp as they are, dolphins cannot chew their food. Therefore, they must result to swallowing their food whole. To a dolphin, an open mouth is a sign of aggression, and clapping jaws are an even greater sign of aggression. This rarely happens unless it is during mating season because dolphins talk without opening their mouth.
Dolphins have many ways of defending themselves from predators in the wild.

Dolphins Species:-

There are more than 40 species, but the number keeps changing as science learns more about these marine mammals. Most dolphins are part of the Delphinidae family, which includes those living in the ocean, but some other species live in rivers and have a different taxonomic classification. Definitively, the best known of all the species is the bottlenose dolphin.
Among those dwelling in freshwater rivers, probably the best-known is the Amazon River Dolphin or Boto, also popular because of its pink skin.
It is astounding the size variety of dolphin species. While the largest the orca, can weigh about 11 tons and reach up to 30 feet long, the smallest species are only 90 pounds and 4 feet long. Between those two limits, there is an assortment of weights and lengths. The living habitat of each species plays a significant role in its overall size as the feeding habits sometimes make size differences even within the same species.

Anatomy

Dolphin Evolution:-

Even though we have significant information about dolphins today, there are still many questions about their origin. Some theories come from the fossils discovered like the hypothesis that millions of years ago dolphins were much smaller than they are today. Many experts also believe that echolocation is a specialization result of the evolution process. Only time, new fossils and future technology will help us to get definite answers about the evolution of dolphins.

Dolphins and Humans:-

Dolphins have been interacting with humans for as long as we have known about their existence. However, during this time, their most dangerous predator and the only one that has dramatically reduced their population is the human. Even though we all agree that, Dolphins are fantastic creatures that seem to be intelligent and friendly, we still are a huge threat to them.
A deeper knowledge and further information about dolphins is the first step towards a better conservation and understanding of these amazing cetaceans.
Trying to provide readable-friendly information about Dolphins, we include articles like “dolphin way of life,” which contains the information about daily dolphin activities, for example, “what do dolphins eat?” or “social relationships,” among others.

Regarding the basic information about dolphins, you will find detailed data about dolphin reproduction, the way they hunt and how they communicate. At the anatomic level, a particular analysis of the echolocation, their basic anatomy and physiology.
The section related to humans is devoted to the relationship between dolphins and humans, including articles which describe encounters with them like the incredible rescues of humans by dolphins. Also, we include a section about how dolphins impacted our culture reflecting this in movies, books and many other ways of expression that have existed for centuries including even the most prominent ancient cultures and civilizations like the Greek and Roman which included dolphins in their mythology.
