No. Sponges belong to the phylum Porifera, which means 'pore bearing.' The have pores that are called incurrent vents, where water comes in, and excurrent vents, where water goes out. They are considered the most primitive of animals because they don't have any complex organs or tissues, so, for example, they don't have a circulatory system or a digestive system or a nervous system. Their cells are somewhat loosely structured in that some cells can move around from place to place in the sponge and there are some unspecialized cells that can become other kinds of cells. Also, they only have two layers of cells. There are some types of sponges that you can put through a sieve to separate all the cells but then the cells will go back together to recreate a sponge again.
Echinoderms are a completely different and more advanced phylum. They have organ systems and fixed (non-changing) cell types and more layers of cells. Also, if you put an echinoderm through a sieve, he's a gonner.
Sponges,Worms,Mollusks,Arachnids,and Echinoderms
Sponges, Cnidarians, Mollusks, and Echinoderms are not Arthropods.

Some things that prey on sponges are sea turtles, crustaceans, fish, and echinoderms. Sponges move so slow that they cannot avoid being eaten.
They eat corals, sponges, sea urchins, other echinoderms, and small crustaceans.

An invertebrate is an organism that lacks a backbone. The 6 groups of invertebrates are sponges, cnidarians, worms, mollusks, echinoderms and arthropods.
Ok vertabrates are animals with no back bones witch can be: sponges, echinoderms, celentrates, ( idont remember how to spell it) that's all i can remember.
well, there are lots, so i`ll just say mammals,birds,fish,reptiles,amphibians,sponges,echinoderms,mollusks,and cnidaria.
No. Porifera (sponges) are heterotrophs. This is a key defining feature of all animals.
Porifera (Sponges)Cnidaria (Coelenterates)Flatworms (Platyhelmenthes)Roundworms (Aschelmenthes - Nematode)Segmented worms (Annelids)Mollusks (Soft-Bodied/ hard shelled Animals)Echinoderms (Spiny-Skinned Animals)Arthropods
No, sponges are not deuterostomes. Deuterostomes are a distinct classification of animals characterized by a particular pattern of embryonic development, which includes echinoderms and chordates such as humans. Sponges belong to the phylum Porifera, and they are considered one of the most basal and primitive animal groups.
