Not all animal phyla possess a backbone or true tissues. Additionally, not all animal phyla exhibit bilateral symmetry or segmentation. Some phyla, like sponges, lack specialized organ systems, while others, like cnidarians, have a simple nerve net instead of a centralized nervous system.
Animal phyla are major groupings of organisms within the animal kingdom based on shared characteristics like body plan, development, and genetic makeup. There are around 35 recognized animal phyla, ranging from simple organisms like sponges to complex organisms like mammals. Each phylum represents a distinct evolutionary lineage with its own unique traits.
Biologists use characteristics such as body symmetry, presence of tissues, body cavity structure, and digestive system type to classify animal phyla. Other features like presence of a backbone, mode of reproduction, and presence of specific body structures are also taken into account for classification. These characteristics help scientists group animals into different phyla based on shared evolutionary traits.
There are around 35 recognized animal phyla and 11 recognized plant phyla, making a total of approximately 46 phyla across the animal and plant kingdoms.
The four major phyla of protozoa are Sarcomastigophora (includes flagellates and amoebas), Ciliophora (ciliates), Apicomplexa (parasites like Plasmodium), and Microspora (intracellular parasites). Each phylum includes a diverse range of species with varying characteristics and lifestyles.
Cnidaria
Phyla are determined by major anatomical features. Does the organism have a spine? Is there a skeleton, and if so is it internal or external? Does it have a shell? Is it motile or sessile? Does it conduct photosynthesis? How many limbs does it have? Does it have hair? Does it have feathers? Does it have eyes? And so forth.

There are four major phyla's of animal-like protists. These four are sarcodina, ciliophora, sporozoa, mastigophora. With ciliophora being the main one.
Bdinophytes
Phylum
There are around 35 recognized animal phyla and 11 recognized plant phyla, making a total of approximately 46 phyla across the animal and plant kingdoms.
There are more than two phyla in the animal kingdom... There are many phyla in the animal kingdom. There are a few phyla of worms and other invertebrates and then you have the vertebrate ohyla. Unless that's what your asking? Did you want the invertebrate and vertebrate in general phyla? That's the only set of 2 things I can think of.
Animals belonging to the same phyla share similar body plans and characteristics. For example, animals in the phyla Chordata, which includes vertebrates like mammals, birds, fish, and amphibians, share a notochord and dorsal nerve cord during their development.
