On the crest of a cross-grained stickleback, that is caught with a crooked pin;
One wife, however, does not suffice to fill the nest with eggs; and the stickleback is a firm believer in the advantages of large families.
For, like almost all polygamists, your stickleback is a terrible fighter.
A kingfisher, an airborne jewel, whirrs past, stickleback in its beak, and disappears into a thicket of riparian willow.
When held in the right place, it could create the illusion that a single stickleback was accompanied by another scout.
The money came from the proceeds of a special experiment devised by Manfred Milinski, of the Max Planck Institute for Evolutionary Biology, a connoisseur of food and fine wine, a zoologist and naturalist who feels equally at home with people and stickleback fish, as we saw in chapter 1.
A real-life example of such a contest was reported in 1987, when Manfred Milinski, now the director of the Max Planck Institute for Evolutionary Biology in Ploen, Germany, studied the behavior of stickleback fish.
A kingfisher, an airborne jewel, whirrs past, stickleback in its beak.
Milinski found that stickleback fish rely on the Tit-for-Tat strategy during this risky maneuver.
Yet each little fish has an understandable incentive to hang back a little and let the other stickleback soak up more of the risk.
