It has no symmetry, and they have jelly like cells that transport food throughout the body. Collar Cells: fires spines that traps food. Spiky things: Protects the Sponges's body.

∙ 6y agoSponges have three different canal structures
1. Asconoid: This is the simplest canal system. Water simply enters and exits the spongocoel
2. Syconoid: Similar to Asconoid. However, the spongocoel is lined with canals.
3. Leuconoid: No spongocoel is present. The body is filled with chambers that receive water from incurrent canals and expel water into excurrent canals.
All freshwater sponges belong to the class demospongiae. All species in the class demospongiae posses leuconoid canals. Therefore, freshwater sponges have leuconoid canal systems

What phylum is most primitive?
Porifera (sponges) is considered one of the most primitive phyla because they lack true tissues and organs, and exhibit a simple body plan without symmetry.
What are special characteristics of porifera?
Porifera are sponges, they have no main organs or tissues. They are a loose aggregation of cells. To eat they pump water though their system and catch the particles in the water. A very basic cell structure.

What type of symmetry are sponges?
an asymmetrical body plan
What is the difference between a hydra and flatworm?
one is segmented
Which phylum of animals has a body plan that is essentially a tube within a tube?
Nematoda- psuedocoelomates
Do all animals have a symmetrical body plan?
Nope, there are some that are asymmetrical. Like sponges.
What are major characteristics of the phylum?
some of the major characteristics of the phylum are a shared body plan, embryonic development patterns, and specific molecular sequences.
What is the phylum of American Pit Bull Terrier?
The phylum can be thought of as grouping animals based on general body plan, as well as developmental or internal organizations. All dogs have the same phylum no matters what breed it is. The phylum of dogs is Chordata.
What type of body covering does sponges have?
Ostia
What is animal phyla?
Animal phyla are major groupings of organisms within the animal kingdom based on shared characteristics like body plan, development, and genetic makeup. There are around 35 recognized animal phyla, ranging from simple organisms like sponges to complex organisms like mammals. Each phylum represents a distinct evolutionary lineage with its own unique traits.
In taxonomy different classes of organisms might be grouped into the next larger category a?
Different classes of organisms are grouped into the next larger category called "phylum" in taxonomy. This grouping is based on similarities in body plan and development.
