Spicules Image: a) Oxeas-styloids-styles I; b) oxeas-anysostrongyloxeas II, c) enlarged tips of oxeas-styloids-styles I; d) enlargement of oxeas-anysostrongyloxeas II; e) plagiotriaenes; f) microscleres (sterrasters, developed and developing); g) enlargement of microscleres (rossettes of sterrasters on the right; spined asters in 2 types, oxyasters and and strongyl- or oxyasters).

Spicules Image: a) Oxeas I with sterrasters; b) anysostrongyloxeas-oxeas II, c) enlarged tips of oxeas I; d) enlargement of anysostrongyloxeas-oxeas II; e) plagiotriaenes; f) enlargement of microscleres (rossettes of sterrasters on the bottom; spined asters in 2-3 types, oxyasters and strongyl- or oxyasters). Sample from Islas del Rosario, Colombia. Notice the larger and thicker megascleres and stouter microscleres in comparison to those pictured in a sample from the Bahamas.
