Flamingo Park / Flamingoland has held a staggering list of species over the years. At its opening, until the late seventies when it was sold, it acted rather as a holding facility for Ravensden stock.
Several elephant seals were brought over by Associated Pleasure Parks from the falklands. One that was dead upon arrival was hastily ferried up to Loch Ness where someone subsequently 'discovered' Nessy's carcass washed up.
One of the seals went to Cleethorpes and, if I remember correctly, Dudley too.
