Damstra and used by permission. The deep-sea sponge Monorhaphis chuni (Hexactinellida) has the world’s largest known biosilica structure! A silicate spicule that can grow up to 3 meters long. That’s at least a meter longer than you! I don’t really know how to construe to enormity of such a structure. . . . → Read More: Huge Silicate Sponge Spicules and the Evolution of Calcification

Amanda Kahn is currently a masters student at well-known Moss Landing Marine Laboratory, considered to be one of the west coast’s premier marine stations. Despite still being in her masters, she is quickly becoming the “go-to” person for deep-sea sponges. Let’s start off “sex week” with the steamy . . . → Read More: “Sleezy” sponge sexuality
