Sponges
I chose the invertebrate of my choice on sponges. Sponges are multi cellular organisms. Sponges are the simplest and most primitive animals on Earth. One fact that I found very interesting about sponges is the fact that they reproduce sexually and asexually. Sponges are porifera in the kingdom Animalia. Their domain is eukarya. Most sponges have three layers of cells that consist of flattened and skeletal cells with many pores. Sponges rely on keeping a constant flow of water in their bodies to survive. They do not have a nervous system. A question that I still have is how the sponges reproduce sexually and asexually. The sources I used wikipedia and Phylum Porifera.
