Reading and lecture discuss some theories about agnostids' possible lifestyle. On the one hand, the writer proposes some theories, providing three reasons of support. However, the lecturer casts doubts on the claims made by the writer, saying that his statements have serious weaknesses.
First, the agnostids weren't free-swimming predators as the writer sustains. This is because arthropods have large, well-developed eyes which help in tracking and catching the prey. Whereas, the agnostids used to have tiny, poorly-developed eyes, and in addition to this some were blind. At least they should have had another feature to help in the process of hunting, but no proof was found. Therefore, the agnostids could not have been free-swimming predators.
Second, seafloor dwellers live in a localized area, and they occupy only a small geographical place, and moreover, seafloor dwellers do not move fast. The writer asserts that agnostids were seafloor dwellers because other primitive arthropods were living this way. Anyway, the lecturer refutes this idea, adding that agnostids occupied large geographical areas, and this means that they were moving fast from one place to another, on long distances. Thus, this standpoint is directly contradicted.
Third, the last theory is not plausible as well, because parasites live on animals in small numbers. Otherwise, a large population of parasites can kill the animal. The proofs found in the fossils show that these marine animals used to live in large populations and, as a result, the last theory does not stand up.
