![]() ![]() ![]() ![]() The other half comprises of large, non-flagellated macromeres, or blastomeres (a type of cell produced by cell division of the zygote after fertilisation) ( ).Īmphiblastula larvae are typically simple structures.īoth types of larvae spend typically no more than 3 days in larval form. One half of the blastulae larvae is covered in small, flagellated cells. Hollow Amphiblastula LarvaeĪmphiblastula larvae, as the name may suggest, are a hollow blastulae (sphere of cells produced during the development of an embryo). Sponge species whose larva are parenchymella include the majority of species in the class Demospongiae ( ).ĭepending on the species, some parenchymella larvae can be quite complex organisms. The flagella aid in the free swimming phase of sponge development and play an important role in finding a suitable substrate to settle upon. ![]()
