Vertebrates.
1 Phoronida-This is another phylum that contains worm-like organisms. 2  These are called horseshoe worms, and they are thin organisms that live in chitinous tubes they secrete. 3  Placozoa-Placozoans are simple animals that were discovered in the 1800's in an aquarium in Europe. The annelids include earthworms, polychaete worms, and leeches. All members of the group are to some extent segmented, in other words, made up of segments that are formed by subdivisions that partially transect the body cavity. Segmentation is also called metamerism. All animals in the Chordate Phylum have backbones. They are also called vertebrates.. The Chordate Phylum is split into Classes. Several Classes are listed below: Mammal Class: These animals usually have hair/fur. They give birth to live young and feed their young with milk. The Moneran Kingdom is split into several Phyla. Each Phylum group contains organisms that have things in common. Below is a list of some moneran Phyla: Bacteria Phylum: These organisms are extremely important and can also be very dangerous. 1 Chaetognatha-this is another group of worms called arrow worms. 2  Chordata-this phylum is probably one of the most familiar to us. 3  We are included in the Phylum Chordata, which includes all animals with a nerve cord (called a notochord) at some stage of their development. There are at least 33 phyla (plural of phylum) of animals. Humans are members of the phylum Chordata. All of the chordates have elongated bilaterally symmetrical bodies. That is to say, the left and right sides are essentially mirror images of each other. The word phylum (plural: phyla) is a category used to classify marine organisms. In this article, you can learn the definition of phylum, how it is used, and examples of phyla used to categorize marine life. Animal Kingdom. The Animal Kingdom is split into several Phyla. Each Phylum group contains organisms that have things in common. Below is a list of some animal Phyla: Chordate Phylum: All the animals which have a backbone. Includes: Fish, Reptiles, Birds, Amphibians, and Mammals.
