Aquarium staff in Blackpool were stunned to discover a shark they did not know about had been living undetected in one of their tanks for years. Staff at the resort's Sea Life Centre were baffled when two shark eggs were discovered in a tank occupied by resident sharks which give birth only to live young.
The centre's marine experts now believe that one of several former curators must have introduced a small tropical carpet shark to the display without recording the fact - and that it has been in hiding ever since.
"When we found the first egg during a routine dive in the ocean tank just before Easter, we initially thought it must be artificial, and part of the tank's theming decor," said senior aquarist Martin Sutcliffe. "We were all completely baffled when we took a closer look and realised it was real, and then we found another one about three weeks later."
A fish expert at the centre has confirmed the four-inch-long eggs come from a carpet shark - so called because of their habit of lying on the seabed.
