They are, indeed, the most simplest multi-cellular marine animal
A sea anenome is a plant, where as a starfish is an animal. Their diets differ and most anenomes can deliver a poisonous shock to another animal.
The simplest multicellular animals are sponges, which belong to the phylum Porifera. Sponges lack true tissues and organs, and their bodies are composed of specialized cells that work together to carry out essential functions like feeding and reproduction. Sponges are filter feeders, drawing in water through pores to extract nutrients.
The simplest form of animal life is found in single-celled organisms, such as protists or bacteria. These organisms have basic structures and functions, without specialized tissues or organs. They rely on diffusion for nutrient exchange and do not exhibit complex behaviors like more advanced animals.
No. Sponges only have a few different types of cells and are among the most divergent animal species. They are sessile and were formerly thought to be plants.

Skeleton made up of spicule supports most sponges .
Because we wanted to call them sponges. Sponges belong to the animal kingdom since they are heterotrophic. Fungi derive food from breaking doown orgainc material in soil. Sponges feed on existing material. This is the difference.
Organism.
Most sponges are marine, but there are some freshwater varieties
Sea Sponges, They Absorb The Most Water Or Any Fluid And Synthetic Sponges Don't Have As Much Absorbency, Also They Don't Have As Many Holes.
Sponges do have some differentiated cells that have different functions but they don't have true tissues like all other animals and plants do. Even though they're included in the Animal kingdom they also symmetry, which most other animals have.
Sea sponges smell and taste bad so that they don't get eaten by most fish
