Types of Specialized Cells in Animals

Choanocytes
- Choanocytes are specialized cells found in sponges.
- They are responsible for creating water currents and capturing food particles through their flagella.
- Choanocytes play a crucial role in filter-feeding and nutrient uptake in sponges.
- These cells are not limited to performing a single specific function as they are involved in both feeding and water circulation within the sponge.

Interstitial Cells
- Interstitial cells are found in the connective tissue of animals.
- They perform various functions such as producing hormones, supporting structures, and participating in immune responses.
- Unlike other specialized cells, interstitial cells have a diverse range of functions within the body.
- They contribute to the overall health and function of the organism by performing multiple tasks.

Gastrodermal Cells
- Gastrodermal cells are present in the gastrodermis of cnidarians.
- They are involved in digestion, nutrient absorption, and waste removal.
- These cells line the digestive cavity of cnidarians and aid in the breakdown of food particles.
- Gastrodermal cells have a specific function related to digestion and nutrient processing in these animals.

Nematocytes
- Nematocytes are specialized stinging cells found in cnidarians.
- They are used for capturing prey and defense mechanisms.
- Nematocytes contain stinging structures called cnidocysts that inject toxins into their targets.
- These cells have a single specific function of immobilizing prey or deterring predators through the use of toxins.

Interstitial cells are the exceptions
