What kind of animals have collar cells an osculum an spicules?
Sponges have collar cells, osculum, and spicules.
What type of animal has cells an osculum and spicules?
Sponges have collar cells, osculum, and spicules.
What type of animal has a collar cells an osculum and spicules?
An animal with collar cells, an osculum, and spicules is likely a sponge. Sponges are simple aquatic animals that filter feed using collar cells and have a central opening called an osculum through which water exits their bodies. Spicules are tiny, hard structures that provide support and structure to the sponge's body.

What organisms are found in porifera?
Porifera are sea sponges. They have no symmetry (asymmetrical) and they are one of the most basic forms of life. They have a 2 cell layer wall made of collar cells, spicules, amoeba like cells, and a layer of epidermal like cells. The spicules and the amoeba like cells are in between the layer of collar cells and epidermal cells. Sponges also have pores throughout their structure. Porifera include freshwater sponges as well of marine varieties. Freshwater sponges are common although not obvious. Frequently they are green in color due to included algae.
What are the characteristics of porifera?
Porifera are pore bearing animals . Pores include ostia and osculum . they possess choanocytes or collard cells .
What are the main characteristic of a sponges?
Sponges are simple, multicellular animals that lack true tissues and organs. They obtain nutrients by filtering small particles from the water through specialized cells called choanocytes. Sponges have a porous body with a system of canals and chambers for water circulation.
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.
Do jellyfish use collar cells for filter feeding?
Jellyfish do not have collar cells. Sponges have collar cells, and yes, they are used for filter feeding.

What are pore cells and collar cells?
collar cell- choancyte that is most likely in sponges
What is the function of spicules?
Spicules are small needle-like structures found in some animals like sponges and sea urchins. They serve various functions including structural support, defense against predators, and aiding in movement.
