**Summary:**
* A person stumbles upon 5 large shark sculptures ("Sharks!") in a London canal, sparking curiosity.

* A bureaucratic battle ensued, with Antepavilion embracing the paperwork as part of the art.
* The sharks were eventually relocated to the Islington Boat Club, but now face removal by the end of the month due to unspecified reasons, with a possible future on a transportable barge.
