Video report by ITV News Meridian's Andy Dickenson
Dolphin sightings have reached record levels this summer with some caught on video - including one of the highest jumps ever recorded off the Sussex coast.
Marine biologists say dolphins are being spotted both close to our region's shores and further out to sea. And they're not alone, a thresher shark has also been seen breaking the water a mile off Cuckmere Haven.
Moments of wonder, once thought rare, now regularly being caught on camera - and that in changing tides could be here to stay.
