Pheronema Pheronema is a genus of deep-sea glass sponges belonging to the class Hexactinellida. These sponges are typically found anchored in soft ocean sediments at great depths, where they filter tiny organic particles from the surrounding water for nutrition. Their bodies are supported by delicate, silica-based skeletal structures that give them a fragile, translucent appearance.
Hyalonema Hyalonema is a genus of deep-sea glass sponges that belongs to the class Hexactinellida. These sponges are known for their long, twisted stalk made of silica spicules, which anchors them securely to the ocean floor in very deep marine environments. Their delicate, lattice-like body structure allows them to filter microscopic food particles from seawater.
Euplectella is a genus of deep-sea glass sponges in the class Hexactinellida, commonly known as the “Venus’ flower basket.” These sponges have a delicate, cylindrical body made of a lattice of silica spicules, giving them a glass-like appearance. They live anchored in soft sediments on the ocean floor and feed by filtering microscopic particles from
