DolphinsDolphins are marine mammals.  There are

almost forty species of dolphin in 17 genera. They vary in size from 1.2 m (4 ft) and 40 kg (90 lb), up to 9.5 m (30 ft) and 10 tonnes (9.8 long tons; 11 short tons). They are found worldwide.

Dolphin’s AttitudeDolphins are among the most intelligent

animals, and their often friendly appearance and seemingly playful attitude have made them popular in human culture.

Amazon River Dolphin or Pink DolphinPink Dolphin is a freshwater river dolphin. This

species looks like the grey dolphin, but are bigger, and, instead of a dorsal fin, they have a hump on their back. The pink dolphin has been listed as endangered specie because of the pollution, overfishing and habitat loss. 

WARNING!!!!

Human threatsSome dolphin species face an

uncertain future, which are seriously endangered. Pesticides, heavy metals, plastics, and other industrial and agricultural pollutants that do not disintegrate rapidly in the environment concentrate in predators such as dolphins. Injuries or deaths due to collisions with boats. In some parts of the world, such as Taiji in Japan and the Faroe Islands, dolphins are traditionally considered as food. Dolphin meat is high in mercury, and may thus pose a health danger to humans when consumed.

Some things we can do to protect dolphinsAvoid contaminating the marine ecosystem with

garbage, plastics, chemistry, as fishing nets placed improperly.

Don`t consume for any reason meat from these cetaceans.

Law No. 26585 which prohibits extraction, processing and marketing of dolphins and other cetaceans.

We can help these friendly animals, rather than they come

to be completely extinct.
