Biff and Dilara were arguing over a news feed regarding population of catfish (Silarus gianis) in France which had figured out how to hunt feral pigeons. A submerged catfish lying in wait would rush in shallow water (liek a killer whale beaching itself when hunting seals). Grab a pigeon that had been drinking or bathing at water's edge, drag it in deeper water, and swallow it. Biff was skeptical and sugeted that if the story had merit, the chance of a successful capture would surely be low: less than be profitable, the success rate would need to be fairly high, perhaps as high as 40%. To investigate, they tracked down to the original article (Cucherousset et a. 2012), which reported that 15 out of 54 attempts were successful. Are these date consistent with Dilara's conjecture, Biff's argument, both, or neither?
