Ostium.
The body of a sponge is covered in tiny openings called pores. These pores allow water to flow in and out of the sponge, which helps the sponge filter out food particles and oxygen from the surrounding water.
No, the small openings on a sponge are called ostia. Setae are bristles or hair-like structures found on some invertebrates like worms or arthropods that help with movement or sensory functions.
Small pores of sponges are called ostia through which water enters while a large pore through which water exits is called osculum .
They are called stomata, openings or pores in the epidermis of leaves.
The surface of the orange puffball sponge is covered with small pores that filter small particles of food from the water that passes through them. Each sponge has flagella that help move the water through the sponge.

Water is moved through a sponge's central cavity, known as the spongocoel, by the action of specialized cells called choanocytes. These cells have flagella that beat rhythmically, creating a flow of water into the sponge through small openings called ostia. As water flows through the spongocoel, it is filtered for nutrients and oxygen, which are absorbed by the sponge's cells. The filtered water then exits through a larger opening called the osculum.
No, ostiums and pores are not the same. Ostiums are small openings in the body, such as the entrance of a sponge's canal system, while pores are tiny openings in the skin or other surfaces that allow substances to pass through.
Openings in a leaf are called stomata. Stomata are small pores located primarily on the underside of a leaf that allow for gas exchange, such as the intake of carbon dioxide and the release of oxygen and water vapor.
You can tell if your kitten is male by looking for two small openings near the anus. If there is a larger space between the openings, it is likely a male kitten. Additionally, male kittens have a small bump called a scrotum between the openings.
