Poriferan

A poriferan, also known as a sponge, is a simple, aquatic invertebrate belonging to the phylum Porifera. Characterized by porous bodies, they lack true tissues and organs. Poriferans are primarily sessile, meaning they remain fixed in one place. They filter water through their pores to extract food and oxygen, showcasing a unique feeding mechanism. They reproduce both sexually and asexually, with varied body plans, including asconoid, syconoid, and leuconoid structures. These ancient organisms are vital components of marine and freshwater ecosystems.
