TURNS out, there may be a reason why some people call getting married, “taking the plunge.”

For one couple, this saying took on a literal meaning. Lauren and Gary Dongray of Harlow, solidified their union by saying “I do” inside a tank at the Sea Life aquarium in Manchester last June.

It was part of the E4 series “Don’t tell the Bride”.

It probably comes as no surprise that the couple also met on the dating website, Plenty of Fish.

The Dongray’s were joined in the tank by Lauren’s six bridesmaids, who were delightfully dressed as mermaids, Gary’s best man, Tony, and Lauren’s dad.

The couple’s golden labrador, Gizmo, served as the “flower girl” and was kept at a second stage — out of the water.

In order to perform the ceremony, the couple, and all humans in attendance, wore oxygen tanks with helmets to keep hair dry.

The couple admits they applied to be on the show as a joke, but went through four months of auditions before being chosen.

Within six weeks of being chosen, the couple was happily married. Clearly everything really is better under the sea.
