Any of the pores in aquatic sponges through which water enters the body?
ostium
What is advantages of the folded body walls in sponges?
Sponges have folded body walls with holes leading to the inside of the animal. The advantage is that water stays in one area allowing the animal to respire.
What is the meaning of dermal ostia IN ZOOLOGY?
Dermal ostia in zoology refer to small pores in the body wall of sponges that allow water to enter their internal canal system for feeding and gas exchange. These pores are essential for maintaining water flow through the sponge's body for nutrient uptake and waste removal.
What are pores and where are pores on a sponges body?
Allow materials to enter and leave the sponge
Do the cells of a sponges have cell walls?
No, the cells of sponges do not have cell walls. Instead, sponge cells are held together by a gelatinous extracellular matrix called mesohyl. This allows for flexibility and mobility of the sponge's body.
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 characteristic do scientists use to classify sponges?
Scientists classify sponges based on their body structure, specifically the presence of pores through which water flows for feeding and gas exchange. Additionally, they consider the type of skeleton sponges have, whether it's made of calcium carbonate, silica, or spongin fibers.
Does sponges have bilateral symmetry in adult?
No, sponges do not exhibit bilateral symmetry in adults. They are classified as asymmetrical or have radial symmetry, depending on the species. Their body structure is more irregular and lacks defined symmetry, which is characteristic of their simple body plan and filtering lifestyle.
How do sponges go to the bathroom?
They take in food and water through tiny pores. They get rid of waste products and extra water through a large hole in their body, usually in the middle of the sponge.
How do sponges respire?
They don't nessessarily breath, yet they do respire. They must have oxygen because they are living animals, so every cell in the sponge takes in oxygen and puts out carbon dioxide.
