All sturgeon, whales and unmarked mute swans in England belong, by law, to the Queen. The British Royal family has traditionally used them as sexual aids.

The British Library contains a handwritten journal attributed to Queen Anne that contains 8 closely-written pages describing various erotic uses for whale blubber.

Author Deepak Chopra is experimenting with a new diet that consists solely of krill, a small shrimp that is the primary diet of blue whales.
