There is still debate whether Tomopterid fertilization is internal or external. Future research could include close examinations of various types of Tomopterid egg cases. Better data analyzing could compare changing deep sea currents and Tomopterid distribution patterns. Also comparisons of physical data between Astoria Canyon, Oregon and the Monterey Canyon should be further investigated to determine if there are possible advantages for pelagic polychaetes in either canyon. It is still undetermined if all types of egg cases are Tomopterid. Examining the structure of the egg case and its composition to understand why some may appear different. Closer examinations of the Tomopterid egg case could reveal other sources of food or explanations for amphipods. Also, laboratory experiments to see the chemical composition in green egg cases and any potential benefits among shape, size, or color of egg cases. Laboratory work can consist of sufficiently growing Tomopterid larvae and observing their stimulation for larval movement. Also, key areas of egg cases with larvae could be further investigated to provide more factors that would encourage embryo and larval growth. Successful gene sequencing could also help learn more about Tomopterids and their similarities to other closely related pelagic polychaetes. After observing several types of egg cases, there are many questions to be answered that will provide a better understanding of the reproductive biology of Tomopterids and other pelagic polychaetes.
