"Trilobites were active predators or sediment ingestors which lived in the seas. Most trilobites were bottom dwellers (benthic), although some free-swimming (nektonic) speices also existed. To protect themselves from attackers, they could roll themselves up into a ball like a wood louse. (...) Trilobites ranged in size from a couple of millimeters to 75 cm. In the Silurian, however, their "days of glory" were long passed, and the remaining species were of a modest size."
