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.
