Agnostids were a group of marine animalsthat became extinct about 450 millionyears ago. Agnostid fossils can be found inrocks in many areas around the world. From the fossil remains, we know thatagnostids were primitive arthropods-relatives of modern-day insects. However, the fossil information does not allowpaleontologists to determine with certaintywhat agnostids ate or how they behaved. There are several different theories abouthow agnostids may have lived. Free-Swimming Predators First, the agnostidsmay have been free-swimming predatorsthat hunted smaller animals. It is knownthat other types of primitive arthropodswere strong swimmers and activepredators, so it is reasonable that theagnostids may have lived that way as well. And while the agnostids were small, sometimes just six millimeters long, therewere plenty of smaller organisms in theancient ocean for them to prey on. SeafloorDwellers Second, they may have dwelled onthe seafloor. Again, there are examples ofother types of primitive arthropods livingthis way, so it is possible that agnostidsdid too. On the seafloor they would havesurvived by scavenging dead organisms orby grazing on bacteria. Parasites Third, there is the possibility that the agnostidswere parasites, living on and feeding offlarger organisms. One reason that thisseems possible is that there are manyspecies of modern-day arthropods thatexist as parasites, such as fleas, ticks, andmites. The agnostids might have lived onprimitive fish or even on other, largerarthropods.
