hey buddy,
so porifera( sponges) are the first phylum of animalia kingdom.
so being the first phylum they are the most basic and simple phylum.
they are multicellular with a body full of pores which allow them to circulation and channeling of water through their whole body.
they are aceolemate.
it means that they body cavity is not lined with mesoderm.
mostly they are non motile and live in aquatic region.
they do not have nervous, circulatory and digestive system.
they maintain a constant flow of water from them to obtain food and oxygen and remove wastes from their body.
hope it will help

1. These animals are with simplest body plan and are called as sponges. They bear numerous pores on their body. These pores are called as 'ostia' and 'oscula'.
2. These are aquatic animals and most of them are freshwater dwellers and marine.
3. Most of them have asymmetrical body.
4. These animals have special type of cells called as collar cells.
5. These animals are always attached to substratum hence they do not show locomotion and they are referred as sedentary animals.
6. Their spongy body is supported by spicules or spongin fibres. Spicules are made up of calcium carbonate or silica.
7. These animals reproduce by budding by sexual or asexual method. Also, they have a good ability of regeneration.
Examples .. Sycon, Hyalonema.
