Poupamos

Poupamos is a genus of marine sponge belonging to the family Hexactinellida, commonly known as glass sponges. These sponges are characterized by their intricate silica-based skeletons, which form rigid, lattice-like frameworks. Poupamos species are typically found in deep-sea environments, often at depths exceeding several hundred meters, where they adhere to rocky substrates or other hard surfaces.

The morphology of poupamos includes a cup-shaped or tubular body, with a porous surface that allows water flow through their canal systems. Their skeletons are composed of silica spicules, which are arranged in elaborate, supportive structures providing both strength and flexibility. This structural complexity facilitates their filtering of nutrients and oxygen from the surrounding water, which is essential for their survival in nutrient-sparse deep-sea habitats.

Poupamos sponges play a significant ecological role by contributing to benthic community dynamics and serving as habitats for various microorganisms, invertebrates, and juvenile fish. Their ability to withstand extreme pressure and low-light conditions makes them important components of deep-sea ecosystems.

Research on poupamos is ongoing, aimed at understanding their biological functions, skeletal formation, and potential applications in biomaterials science. Their silica skeletons have drawn interest for potential uses in lightweight, durable composite materials and bio-inspired engineering.

Due to their deep-sea habitat, poupamos are less well-known compared to shallow-water sponges, and their biological processes remain an active area of scientific investigation. Their resilience and unique skeletal architecture continue to offer insights into adaptation strategies in extreme environments.
