Hexactinellid

(Redirected from Hexactinellida)

Hexactinellid sponges are sponges with a skeleton made of four- and/or six-pointed silaceous spicules, often referred to as glass sponges. They are usually classified along with other sponges, but some researchers consider them sufficiently distinct to deserve their own phylum, Symplasma.
