Sponge spicules (amorphous silica structural elements) are most often large (~0.1 to >1 mm), needle-like, gently curved, sometimes with a medial groove or tube. Ends may be pointed or rounded. Surface is frequently smooth and unornamented, but may be covered with prominent bumps. Distinguished from diatoms by size, lack of ornamentation, robustness/solidness. Marine forms may be more complex, tri- or tetraxial. Marine forms may less commonly be calcareous instead of siliceous. | Acicular
