Sponges are invertebrate animals that usually have no body symmetry and never have tissues or organs. Cnidarians use stinging cells to capture food and defend themselves. Flatworms are flat and as soft as jelly. Unlike cnidarians or flatworms, roundworms have a digestive system that is like a tube, open at both ends. Earthworms and other segmented worms have bodies made up of many linked sections called segments.

What are the types of annelids?
The three main types of annelids are polychaetes, oligochaetes, and hirudineans. Polychaetes are marine worms with bristles, oligochaetes are terrestrial or freshwater worms with few bristles, and hirudineans are leeches. Each type has unique characteristics and habitats.

What is the segmentation for cnidarians?
Cnidarians are segmented into two main classes: Anthozoa (sea anemones and corals) and Medusozoa (jellyfish and hydrozoans), based on their body forms. Anthozoa are generally sedentary, with a polyp body form, while Medusozoa are typically free-swimming with a medusa body form.

What main characteristics are used to classify animals into different phyla?
The main characteristics that are used to classify animals into different phyla includes the cell type, the cell wall and the nuclear membrane. The presence of the absence of a backbone is another main characteristic.

The six types of Invertebrates are: Arthopods, Annelid Worms, Mollucs etc There could be five or seven types of invertebrates. The following are types of invertebrates: arthropods, cnidaria, echinoderms, mullusks, flatworms, roundworms, and segmented worms. Flat worms, roundworms, and segmented worms are could be grouped together, making seven types turn into five.
