Needle Sponges [Pheronema]

Description

Pheronema, or needle sponges, is a genus within the family Hyalonematidae, characterized by their needle-like spicules that provide structural support and defense mechanisms. These sponges are primarily found in deep-sea habitats, where they attach to the ocean floor and extend their bodies upwards to filter feed. Needle sponges have a unique appearance, with their spicule network creating a distinctive, often spherical or elongated body shape. They play an important role in their ecosystems, serving as biofilters and habitats for various microorganisms.
