Expected National Dolphin Day Deals

As a Cause holiday, National Dolphin Day focuses on raising awareness and funds for marine conservation rather than commercial deals. Organizations like the Dolphin Research Center, Whale and Dolphin Conservation (WDC), and the National Marine Sanctuary Foundation often run donation drives and educational campaigns. Many marine parks and aquariums, such as SeaWorld (through its conservation fund) and the Georgia Aquarium, offer special educational programs or discounted admission on or around this day, with proceeds often supporting their research and rescue efforts. Online retailers like Etsy and Amazon may feature dolphin-themed merchandise where a portion of sales benefits marine life charities. We encourage direct donations to reputable conservation groups. We will update this page with confirmed live conservation initiatives as April 14 approaches.

National Dolphin Day Hero

Jacques Cousteau

Jacques-Yves Cousteau (1910–1997) was a French naval officer, explorer, conservationist, filmmaker, and researcher who pioneered marine conservation. Co-inventor of the Aqua-Lung, his documentaries and books, like 'The Silent World,' brought the ocean's wonders, including dolphins, into millions of homes, inspiring generations to explore and protect marine life. His work significantly raised global awareness about ocean ecosystems and the need for their preservation.

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.
