11 Incredible Uses of Sea Sponges You Never Knew

Sea sponges are intriguing marine animals that many people often mistake for plants. These simple, multicellular creatures boast an assortment of shapes, sizes, and colors, and are characterized by their porous structure. Despite lacking true organs, tissues, and a nervous system, sea sponges are quite remarkable sea creatures.

Diverse Types of Natural Sea Sponges

With over 5,000 species in existence, sea sponges can be generally classified into three primary categories: calcareous sponges, glass sponges, and demosponges. Each type possesses its own unique characteristics and properties, which determine its various applications.

Calcareous Sponges

    Calcareous sponges are a class of marine sponges, known as Calcarea, characterized by their calcium carbonate spicules. These spicules are needle-like structures that provide support to the sponge's body. Calcareous sponges are usually small and can be found in various shapes, such as tubes, cups, or irregular masses. They inhabit shallow waters, typically in areas with rocky or sandy substrates.

    Glass Sponges

      Glass sponges, belonging to the class Hexactinellida, are unique due to their silica-based spicules, which form a delicate and intricate lattice-like structure. These sponges are often found in deep-sea environments and can grow to be quite large. Glass sponges are characterized by their glass-like, transparent appearance and often display a variety of shapes, such as a vase, fan, or basket-like structures.


        Demosponges, or class Demospongiae, are the most diverse and abundant group of sponges, accounting for approximately 90% of all known sponge species. They have a variety of shapes, sizes, and colors, and can be found in a wide range of habitats, from shallow coral reefs to deep-sea environments. Demosponges possess a flexible, protein-based skeleton with siliceous spicules, and some species also incorporate spongin fibers, which provide additional structural support.
