WHY THIS DAY MATTERS

Why We Love National Dolphin Day

Dolphins help humans too!

Not only are dolphins amazing creatures to observe in nature, but they also provide us with valuable assistance. Dolphins in some parts of the world can be trained to herd fish into fishing nets which helps fisherman catch more fish with less effort - now how cool is that?

Dolphins are intelligent & playful creatures

Dolphins are one of the most intelligent animals in the world. They have complex social behaviors and interactions, showing empathy and even grief towards one another. They also love to play, doing tricks like leaping in the air or 'surfing' on boats for fun!

Dolphins have unique calls & whistle languages

Dolphins are able to communicate through a wide range of vocalizations, including clicks, whistles, squeals, and squeaks. Researchers have found that these calls are used to express feelings and form relationships with other dolphins within their pod.
