Also sometimes known as the Goiter Sponge, the Chalice sponge is a species of glass sponge (Order: Hexactinellida) that occurs in deep off of the western seaboard of North America. Heterochone calyx is commonly seen growing in large “forests” on the upper portions of seamounts, where currents concentrate food particles. Like most sponges H. calyx is a filter feeder and will filter the water around it for nutrients.
