Sponges

Step-by-step explanation:

Sponges have larvae that are motile and move via the motion of cilia

  • Sponges are simple aquatic invertebrates and belong to phylum porifera of kingdom animalia.
  • Sponges have numerous pores called ostia on the surface.
  • Asexual reproduction occurs through budding.
  • Sexual reproduction in sponges produces larva called Stomoblastula.
  • The stomoblastula attaches on the nurse cells and feeds on them for few days.
  • As soon as it develops into an amphiblastula, it turns inside out bringing out cilia which helps it to swim in water.
