They do not have mouths they have tiny pores that draws in their water.
Sponge cells are largely independent of each other and can form new sponges if separated. They contain specialized cells which allows them to do so. Porifera can break down into three main groups which are, calcareous sponges, glass sponges, and demospongiae.

All the cnidarians having nematocysts that are stinging cells used for defense and preying. Most of the species of cnidarian live in the marine environment and tropical regions of the ocean. They are soft bodied and have radial symmetry.

The five classes of echinoderms are starfish, brittle starts, sea cucumbers, sea urchins, and sea lilies. Echinoderms have cells that possess toxins. They also have a very simple nervous system with five radial nerves extending along the arms and no structure resembling a brain. In order to reproduce, echinoderms can release echinoderms can release their sperm and eggs into the water to be fertilized, or they can reproduce asexually by regeneration. The difference between the classes is sea stars have thick arms used to grab prey, brittle stars have thin arms, that wrap around prey, sea urchins and sand dollars, are flattened discs and do not have arms, sea cucumbers lie horizontally rather than stand vertically, sea lilies and feather stars are suspension feeders.

Nearly all annelids have a fluid-filled cavity between the outer body wall and the gut. Annelids have a body covered by an external cuticle that is never shed or molted. Annelids have a brain or cerebral ganglion that originates and usually resides in the head. The brain varies in structure, with mobile active forms having the most complex brains, and sessile or burrowing forms having simple brains with little differentiation. The three classes of annelids are marine annelids known as polychaeta, marine freshwater and terrestrial annelids including earthworms called oligochaeta, and marine, freshwater and terrestrial leeches called hirudinea.

Segmentation affects both external and internal structure. Their body is covered in an exoskeleton made of proteins. Each body segment has jointed limbs. They grow by molting their exoskeletons. In order to reproduce, most arthropods lay eggs.  The classes of arthropoda are insecta, arachnida, diplopoda, chilopoda, entognatha, and malacostraca. These classes have difference in main body regions, the amount of legs, antennae, and whether or not they have wings.

The only body cavity that flatworms possess is the gut. Flatworms must respire by diffusion. The four groups of flatworms are turbellaria, monogenea, trematoda, and cestoda. Turbellaria includes many marine species. Flatworms are acoelomates.

Their body is composed of more than two cell layers, tissues and organs. They lack a body cavity. They have a through gut with a mouth and anus. Mollusca have shells of protein. They have a nervous system with paired nerve chords. Mollusca has an open circulatory system with a heart and aorta, gaseous exchange organs, and a pair of kidneys. They normally reproduce sexually. They are divided into seven classes that differ in shell shape and size.

The dorsal hollow nerve cord develops into the central nervous system: the brain and spine. They have openings in the pharynx that develop into gill arches and are called pharyngeal slits. The classes of chordates are, reptilia, amphibia, chondrichthyes, agnatha, and mammalia. The chordates that are considered invertebrates lose their notochord when they become an adult.

They are free living organisms that are parasitic. They have three germ layers. Their body cavity consists of pseudocoelom. Nemotoda are divided into enoplea and chromadorea. Both classes consist of free-living and parasitic roundworms that live in freshwater, marine water, the soil, or a host.
