The kingdom Animalia is classified into multiple phyla. Here is a list of 35 phyla within this kingdom:
- Porifera (sponges)
- Cnidaria (jellyfish, corals, sea anemones)
- Platyhelminthes (flatworms)
- Nemertea (ribbon worms)
- Nematoda (roundworms)
- Annelida (segmented worms)
- Mollusca (snails, clams, octopuses)
- Arthropoda (insects, arachnids, crustaceans)
- Echinodermata (starfish, sea urchins)
- Chordata (vertebrates and some invertebrates)
- Ctenophora (comb jellies)
- Hemichordata (acorn worms)
- Urochordata (tunicates)
- Cephalochordata (lancelets)
- Tardigrada (water bears)
- Onychophora (velvet worms)
- Bryozoa (moss animals)
- Gastropoda (snails and slugs)
- Bivalvia (clams and oysters)
- Cephalopoda (octopuses and squids)
- Arthropleura (ancient millipede-like organisms)
- Ectoprocta (moss animals)
- Phoronida (horseshoe worms)
- Kinorhyncha (mud dragons)
- Priapulida (penis worms)
- Acanthocephala (thorny-headed worms)
- Micrognathozoa (tiny jawed organisms)
- Rotifera (wheel animals)
- Nematomorpha (horsehair worms)
- Scyphozoa (true jellyfish)
- Hydrozoa (hydroids)
- Anthozoa (corals and sea anemones)
- Myxozoa (parasitic organisms)
- Placozoa (flat animals)
- Porifera (sponges) - (repeated, perhaps as part of taxonomy in certain contexts)
Note: The classification of phyla can vary depending on current research and phylogenetic studies, and some phyla may have been grouped or split as our understanding of animal evolutionary relationships evolves.
