Flower such as the "Sarracenia" or lady-slipper orchids, have elaborate designs to ensure pollination while preventing self-pollination. "Anemophilous": flowers use the wind to move pollen from one flower to the next, examples include the grasses, Birch trees, Ragweed and Maples. They have no need to attract pollinators and therefore tend not to grow large blossoms. Whereas the pollen of entomophilous flowers tends to be large-grained, sticky, and rich in protein (another "reward" for pollinators), anemophilous flower pollen is usually small-grained, very light, and of little nutritional value to insects, though it may still be gathered in times of dearth.

Slipper lobster Although they are fished for wherever they are found, slipper lobsters have not been the subject of such intense fishery as spiny lobsters or true lobsters. The methods used for catching slipper lobsters varies depending on the species' ecology. Those that prefer soft substrates, such as "Thenus" and "Ibacus", are often caught by trawling, while those that prefer crevices, caves and reefs (including "Scyllarides", "Arctides" and "Parribacus" species) are usually caught by scuba divers. The global catch of slipper lobsters was reported in 1991 to be . More recently, annual production has been around , the majority of which is
