Welcome to planet Acantharia!

Acantharia are most recognisable by their array of spicules, which are composed mainly of strontium sulphate (aka celestite) and barium, extending from a single cell (Larnik & Westheide,2011). Interestingly, Acantharia are the only known marine organisms capable of biomineralising strontium sulphate.
