anthozoan

Everyday forms of resistance make no headlines. Just as millions of anthozoan polyps create, willy-nilly, a coral reef, so do thousands upon thousands of individual acts of insubordination and evasion create a political or economic barrier reef of their own. There is rarely any dramatic confrontation, any moment that is particularly newsworthy. And whenever, to pursue the simile, the ship of state runs aground on such a reef, attention is typically directed to the shipwreck itself and not to the vast aggregation of petty acts that made it possible. It is only rarely that the perpetrators of these petty acts seek to call attention to themselves. Their safety lies in their anonymity. It is also extremely rarely that officials of the state wish to publicize the insubordination. To do so would be to admit that their policy is unpopular, and, above all, to expose the tenuousness of their authority in the countryside—neither of which the sovereign state finds in its interest. The nature of the acts themselves and the self-interested muteness of the antagonists thus conspire to create a kind of complicitous silence that all but expunges everyday forms of resistance from the historical record.

Tube Anemone (Order: Ceriantharia) by mad-as-a-marine-biologist

Tube-dwelling anemones are not in fact ‘anemones’ but different subclass of anthozoans. They are solitary, living buried in soft sediments. Tube anemones construct their tubes out of a fibrous material that is secreted from mucus and threads of nematocyst-like organelles.
