There must be something in the water. These little rays of sunshine appear to be smiling at just days old.

While the nation eagerly awaits news of the Royal baby, these babies have brought visitors flocking to Great Yarmouth’s Sealife Centre.

They were born during a baby boom at the centre, where at least six Thornbacked rays have hatched over the last three days alone.

And visitors eager for a glimpse of their seemingly happy faces say they certainly make life smiles better.

Curator Christine Pitcher said: “We took more ray eggs out of our main display tank this morning, and at least 20 of them seem to be fertile.”

“It’s the right time of year for a baby boom, but I don’t recall ever having so many youngsters appearing at once before.

“It’s the ultimate endorsement for our husbandry techniques and the quality of water and theming in our displays.” she added.

Though the fish appear to be smiling, what looks to be it’s eyes are in fact gills for breathing on it’s underside. The ray’s real eyes are on the front of it’s body.

The fish will live in a nursey tank until they are big enough to join the adult rays in huge open top tank.

Thornbacked rays are the most common of nine species of Rays in British waters. They can grow up to 1.2 metres.

They get their name because their upper body is covered in tiny prickles.

Christine and her team are hoping the baby boom will rub off on their largest resident Aphropdite the nurse shark who has been mating with male Hercules.

“That would certainly be the ‘happy event’ of the year,” she said.

Other animals famous for their happy faces include penguins and dolphins.
