Soon enough, Mr. Fischl and his generation were flushed out of Eden by the next wave, led by Jeff Koons with his gigantic kitschy rabbit sculptures and Damien Hirst with his embalmed tigershark floating in formaldehyde.
One tigershark they caught turned out to have a hook already lodged deep in its stomach, so they used a long pole called a de-hooker to reach inside and remove it, returning the shark to the ocean healthier than it had arrived.
At the time, some theorised that a male tigershark kept at the zoo could have been the father - but the institution's three bonnethead females had none of the bite marks that are usually inflicted on their gender during shark sex.
For many large coastal shark species, the drop in numbers was much greater: tiger, scalloped hammerhead and dusky shark populations have fallen by more than 95%.
