Not all sponges will thrive in a high-CO2 ocean: Review of the mineralogy of calcifying sponges

Reblogged from Ocean acidification: Most marine sponges precipitate silicate skeletal elements, and it has been predicted that they would be among the few “winners” among invertebrates in an acidifying, high-CO2 ocean. But members of Class Calcarea and a small proportion of the Demospongiae have calcified skeletal structures, which puts them among those calcifying organisms which […]
