Common Names
There are no common names specifically assigned to the Malacalcyonacea order.
Characteristics
Malacalcyonacea sponges are distinguished by the presence of malacanthid spicules. These spicules have a specific morphology, characterized by their long, slender shape with a pointed tip. They are often arranged in bundles or fascicles within the sponge's skeleton, contributing to the overall structure and support of the organism.
In addition to malacanthid spicules, Malacalcyonacea sponges may also exhibit other types of spicules, including triaxon spicules. These spicules have three axes of symmetry, forming a three-dimensional structure. The presence and arrangement of different spicule types vary depending on the species within the order.
Environments
Malacalcyonacea sponges are primarily found in marine environments, with a distribution that spans various regions, including the Indo-Pacific. They typically inhabit shallow to deep-water habitats, depending on the specific species. Some species are found in association with coral reefs, while others prefer soft substrates.
