The RCTS book on the Hughes and Stanier 2-6-0s says that other nicknames for the Stanier locos were lobsters and camels. I guess there were plenty of diesels with mollusc nameplates. BTW, the RCTS book does not have the story of the initial design having the cylinder axis higher than the driving axle centre which you mentioned, nor does Langridge. Where is this information from please? Presumably they looked at the drawing of the 43xx as a starting point.
