WSU Biology 106 Exam 3 >> Questions and Answers Updated | 2024 Spongocoel the large central cavity of sponges. water enters the spongocoel through tiny pores called ostia and it exits through the large opening called the osculum. spongocoel is lined with choanocytes which help to create a current in the water. Spicule structural elements found in most sponges. They provide structural support and deter predators. Large ones are called megascleres while microscopic ones...
