Biology Level 2

You discover a new invertebrate species in its larval form. As the zygote was developing, you found that it underwent a spiral pattern of cleavage. Following gastrulation, you determined the species is triploblastic. The blastopore, you noticed, later became the mouth. Finally, after undergoing further development, the larval form of the species turned out to be bilaterally symmetric.

Take the product of the numbers associated with the following phyla to which this species could belong:

\( 2) \) Mollusca

\( 3) \) Arthropoda

\( 5) \) Annelida

\( 7) \) Echinodermata

\( 11) \) Platyhelminthes
