They dont need to eat
No, they are from the Phylum Porifera.
Both flukes and cnidarians possess a gastrovascular cavity for digestion. This cavity serves the purpose of digestion and distribution of nutrients throughout the organism's body.
By diffusion of nutrients from the digestive chamber. In some larger jellyfish there are some specialised cells in the mesoglea that transport nutrients to the outer cell wall. Colony cnidarians have connecting tunnels from the main digestive chamber
small cnidarians and big cnidarians
The cnidarians are in the Kindom family
cnidarians have no nervous system
Yes, cnidarians are invertebrates.
Cnidarians, such as jellyfish and corals, excrete waste primarily through diffusion across their body surface. They do not have specialized excretory organs like kidneys. Waste products, such as ammonia, are released into the surrounding water through their skin and tentacles.
Nope - Cnidarians are marine creatures !
cnidaria(similar to cnidarians)
Cnidarians reproduce asexually and sexually
The tissue that lines the gastrovascular cavity in organisms like cnidarians is called gastrodermis. It is responsible for digestion and absorption of nutrients from the food.
