- Hexactinellid - Wikipedia
Hexactinellid sponges are sponges with a skeleton made of four- and or six-pointed siliceous spicules, often referred to as glass sponges They are usually classified along with other sponges in the phylum Porifera, but some researchers consider them sufficiently distinct to deserve their own phylum, Symplasma
- Hexactinellida | INFORMATION | Animal Diversity Web
The skeleton of an hexactinellid is made entirely of silica These siliceous spicules are generally composed of three perpendicular rays (and therefore six points, so they are described as hexactine), and are often fused, lending hexactinellids a structural rigidity not typical of other sponge taxa
- Hexactinellida - University of California Museum of Paleontology
What's a Hexactinellid? The hexactinellids, or glass sponges, are characterized by siliceous spicules consisting of six rays intersecting at right angles, much like a toy jack
- Hexactinellida - an overview | ScienceDirect Topics
Except for the recently discovered larva of Oopsacus minuta, a hexactinellid sponge, in 1993 and 1994, there are basically three different kinds of larvae In all sponges that have been studied, these larvae are: parenchymula, amphiblastula, and simple blastula
- Hexactinellida - Digital Atlas of Ancient Life
Hexactinellida are characterized by having siliceous hexactine (six-pointed) spicules, making them the second class within the major sponge group Silicea They also construct two different body plans: sycon and leucon
- Hexactinellida (Glass Sponges) - Encyclopedia. com
Hexactinellids (glass sponges) are deepwater marine sponges that have skeletons of siliceous (glass) spicules with a distinctive triaxonic (cubic three-rayed) symmetry Unlike the other two main classes of sponges (Calcarea and Demospongiae), glass sponges lack either a calcareous or organic skeleton

- Hexactinellid
Hexactinellida, commonly referred to as glass sponges, comprise a class of exclusively marine sponges (phylum Porifera) characterized by siliceous spicules exhibiting hexactine (six-rayed) and triaxonic symmetry, which form rigid, translucent skeletal frameworks
