• Triactine I: regular (equiangular and equiradiate); actines are slightly conical to conical, straight and blunt at the tip.
• Triactine II: regular (equiangular and equiradiate) in most cases, although sagittal spicules are also present. These spicules are very small. Actines are conical, straight and blunt at the tip.^[1]
