👉 Nemertinoids are a group of small, often spherical, multicellular animals that belong to the class of protists and have a single cell nucleus surrounded by a membrane called a nuclear envelope. They possess a simple, motile cell wall made of cellulose or chitin, which is essential for their ability to grow into larger structures like nematodes. This type of organism plays an important role in many ecosystems as decomposers, where they break down dead organic matter and recycle nutrients
