Some nudibranchs will even absorb a sponge’s toxin while it eats it and then uses the toxin in its own defense.Īs water filters through a sponge’s porous exterior, the sponge gains some motion, receives food and oxygen, and dispels waste. Who eats sponges? Two organisms that eat sponges though are hawksbill sea turtles and nudibranchs. They whip their flagella constantly to create a current which pulls water into the sponge through the pore cells. The inner body wall consists of choanocytes (collar cells). Water enters the sponge through the pore cells. How does a sponge move water through its body quizlet? Inside the sponge, there are flagella that create currents so their collar cells may trap the food. Their pores allow them to filter the water around them for food. Their skeleton types allow them to live in either hard or soft sediments. What adaptations do sponges have? Certain sponge species are adapted to freshwater environments. Sponges even use the choanocyte when it’s time to reproduce. 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. In some sponges, ostia are formed by porocytes: single, tube-shaped cells that act as valves to regulate the flow of water into the spongocoel. What is the function of pores in the body of sponges? In addition to the osculum, sponges have multiple pores called ostia on their bodies that allow water to enter the sponge. Sponge facts: there’s a “hole” lot to learn | Animal Fact Files Porocytes control the flow of water through pores in the sponge body.
