A wasp drops onto the pond, flails about a bit in an unequal struggle with the surface tension and, GLOMP! A fish snaps it up and disappears. Then – Splash! Thrash! PWARGH! Wasp floats to the surface, not so lively but still kicking. Another fish eyes it up. GLOMP! Then PWARGH! And back comes the wasp, this time with distinctly critical vital signs. Fish Number Three approaches, gets a bead on its profile and GLOMP! Fish disappears. I wait. No regurgitation; this wasp is being recycled. To recycle a wasp, it’s smart to be Third Fish.
