National Dolphin Day is celebrated on April 14 every year. On this day, we celebrate dolphins — one of the most intelligent and friendly mammals in the world. Dolphins are cetacean mammals that belong to the same family as whales and porpoises. There have been many representations of dolphins in popular culture through books and films. Most of these popular representations are accurate. Dolphins are extremely social and friendly beings. They love company and have an acute sense of hearing. Yes, they can hear many more frequencies than adult humans. Dolphins can be found in many parts of the world although they prefer shallow waters.
History of National Dolphin Day
About 50 million years ago, certain four-legged land creatures started spending more and more time in the water, and they gradually started evolving. Their bodies became different and they eventually lost the ability to be mobile on land. These creatures are now known as dorudons and, like dolphins, they were aquatic mammals.About 30 million years ago, squalodons lived in our waters. These toothed whales were not direct ancestors of dolphins as we know them today, but they did use echolocation. Echolocation is the tactic used by dolphins to navigate deep waters using sound waves. The use of echolocation is a key characteristic of both squalodons and dolphins.About 20 million years ago, during the Miocene era, echolocation developed to be the way we know it today. Aquatic creatures which are now known to be connected to extinct dolphin-like creatures called Kentriodontids had active echolocators and even moved around in schools like dolphins do. Thus, over the years, these creatures have evolved to become the dolphins that we know and love today.Dolphin numbers are at risk of endangerment due to poaching and hunting. Global warming and climate change are also causing many dolphins to die. In 2009, the American documentary film “Cove” directed by National Geographic Photographer Louie Psihoyos brought to light the many atrocities associated with dolphin hunting practices in Japan. The film won an Academy Award for Best Documentary Feature in 2010, and helped spread awareness of dolphin hunting and how this affects their numbers.
