. Polyps are dimorphic, consisting of autozooids and siphonozooids. Autozooids are prominent, oval and usually distributed on one side of the colony. When contracted, the autozooids cannot fully retract into the cortex. Siphonozooids are fertile, usually inconspicuous or appear as papillae and are distributed near the base of autozooids. Sclerites include small rods, crosses, 6 -, 7 - and 8 - radiates; double clubs are only present in some species and vary in shape. Long rods or spindles are usually present in tentacles.
