How do sponges move from place to place9/21/2023 People often think of sponges as plants, rather than being animals. They stay put in one place stuck to the bottom of the water- either salt or fresh. Like plants they do not move, i.e., they are sessile. This misconception is due to some of the characteristics of the Porifera (Dawkins 2004). The flagella and collar work together to gather food. Sponges use the flagella to move when they are larvae. It’s a cell that has three basic parts: flagella, collar, and cell body. Those flagella are part of a cell called a choanocyte. Without continuous flow of water, they cannot survive. Water is main resource for their respiratory, circulatory, and digestive system. Water carries nutrients when it enters the sponges and carries out waste when it exits. It is sessile: it cannot move from place to place the way most animals can.
