Skeleton:
Ectosome: Dermal membrane with bundles of diacts in horizontal clusters plus Anisochelae.
Choanosome: Acanthostyles with heads embedded in basal spongin. Echinating tracts arise from here to surface. Surrounding tissue with loose megascleres and Anisochelae.
Distribution: Central to Northern California.
Depth: Intertidal to deep water, 79 meters.
Note: Northwest Pacific specimens tend to have higher means and upper ranges for all spicules. Was Hymdesanisochela rayae.
