Another, dis-similar, dwarf yellow sponge has been found in the Mediterranean in the early 21st century; genetic analysis has confirmed that it is a miniature form of A. aerophoba. [4] The dwarf form is a bright sulphur yellow colour and forms small lobular patches on the surface of rocks.
The calcareous sponges [2] [3] (class Calcarea) are members of the animal phylum Porifera, the cellular sponges. They are characterized by spicules made of calcium carbonate, in the form of high-magnesium calcite or aragonite. While the spicules in most species are triradiate (with three points in a single plane), some species may possess two ...
