There are many different kinds of sponges. Every time you see a sponge with a different shape and color, that is a different species. There are thousands of different species of sponges, tube sponges, encrusting sponges, demosponges, etc. But yes, Porifera only includes sponges. So sponges are the only animals in the Porifera.

What kind of invertebrate is a sponge?
sponge is a porifera .......diploblustic and have only tissue level of organisation.
Is sycon a freshwater sponge?
no porifera only location in see water
What meaning of phylum porifera?
Porifera (pōrĭf'ərə) [Lat.,=pore bearer], animal phylum consisting of the organisms commonly called sponge. It is the only phylum of the animal subkingdom Parazoa and represents the least evolutionarily advanced group of the animal kingdom. All adult sponges are sessile (nonmotile), and nearly all are marine; there are four families of freshwater sponges. Sponges are subdivided into three classes.
What are the Simplest group of invertebrate called?
Sponges (Porifera)Sponges are aquatic animals that make up the phylum Porifera (pohr-IF-uhr-uh). These simple organisms clearly represent the transition from unicellular to multicellular life.
Does phylum porifera have a heart?
No, they are sponges. Actually they are the only animal phyla that does not have any "true tissues".
What members of porifera are diploblastic?
Porifera (sponges) have no specialized cells. To be diploblastic animal phyla must have a minimum of two cell layers referred to as ectoderm and endoderm. The absence of these cell types make it impossible for any members of porifera to be diploblastic.
What makes the group porifera unique?
Obviously the fact that when a porifera farts it is odorless. That is a talent that only porifera and John Travolta have.
What is the only multicellular animal without a nervous system?
a sponge does not have a nervous system
What kingdom includes plankton?
The kingdom that phytoplankton are apart of is called Protista. To be a protist the organism also has to be apart of the other Eukaryotic kingdoms.
Which phylum shows the presence of sponge in fibres in its organisms?
Some members of Phylum Porifera show presence of spongin fibers . These fibers are present only in some fresh water sponges which are used as bath sponges .
What is the only animal phylum that does not have tissues and symmetry?
The phylum Porifera (sponges) is the only animal phylum that lacks true tissues and symmetry. Sponges are simple multicellular organisms with specialized cells, but they do not have tissues that are organized into distinct structures like other animals. Additionally, sponges exhibit asymmetry rather than bilateral or radial symmetry found in other phyla.
If an animal by definition has to move how can a sponge be an animal and not move?
The definition of animals only says that most have independent motion. Stationary animals (sponge, coral, anemones, and some mollusks) get food without moving around.Animals are differentated from plants by structure and being exclusively heterotrophs, or consumers.
