Question

Which phylum do I belong to? My body is made of pores. I live in water. I do not have a backbone also ---.

Answer 1

Hint:- Phylum is a taxonomic ranking that, after domain and kingdom, falls third in the classification hierarchy. In a phylum, species share a set of characteristics that separate them from organisms in another phylum. Approximately 35 animal phyla, 12 plant phyla, and 7 fungal phyla are present. The bacteria are classified into approximately 34 phyla, including the archaea.

Complete Answer:-
The smallest multicellular animals belonging to the Animalia Kingdom are the Phylum Porifera. The term "Porifera" refers specifically to the pore bearers or species of pore bearing. Sponges are proven to be animals based on embryological experiments and are categorized in animals as a distinct phylum. Around 5000 species are included in this phylum. Poriferans were the first multicellular pore-bearing species. The pores are referred to as Ostia.
Poriferans have a spongy texture and are often referred to as sponges. They are connected and do not pass to the substratum. They have the power to absorb fluids and withhold them. Because of the green colour and their symbiotic relationship with algae, they were originally considered plants. Eventually, their life cycle and feeding system were known, and the animal kingdom included them.
So, the answer is Porifera.

Note:- Porifera includes a famous example of Euplectella. These are sometimes referred to as flower baskets of Venus and are found in deep waters. The body, fixed in the mud at the bottom of the sea, is cylindrical, long, and curved. There is a simple syconoid form in the canal system. The skeleton consists of silica spicules that form a three-dimensional structure with parietal gaps at the tips fused.
