Russian Doll Glass Sponge [Lanuginella]

Description

Lanuginella is a genus of glass sponges within the family Lanuginellidae, known for their intricate and delicate skeletal structure made of silica. These sponges resemble traditional Russian dolls due to their unique layered, nested appearance. They are found in deep-sea environments and are characterized by their cylindrical shape, with a series of concentric layers or 'chambers' that decrease in size inwardly, similar to the design of Russian nesting dolls. The genus is distinguished by its spicules - minute, needle-like structures that form the sponge's skeleton. These spicules are arranged in a specific pattern that provides both support and defense against predators. Lanuginella species play a role in deep-sea ecosystems by contributing to the silicon cycle and providing habitat for other marine organisms.
