Information

Stypopodium schimperi is a laminar brown alga that has thin, fan-shaped appendages with longitudinal divisions. It can reach a height of 30 cm and is almost transparent in appearance with a slight brown coloration. The appendages are covered with concentric rows of hairs without any calcification.

Stypopodium schimperi is predominantly found on rocky substrates at depths of 0–20 m, although in the eastern Mediterranean it can be found down to 80 m.

Stypopodium schimperi undergoes alternation of generations; it can reproduce by both gametophyte and sporophyte structures, which are morphologically similar. Gametophytes can, however, be distinguished by the presence of discontinuous dark bands between the concentric bands.

It can be confused with the native alga Zonaria tournefortii. Both species are highly polymorphic, and the best character to distinguish them under a microscope is the number of cortical cell layers: 4–5 cell layers in S. schimperi and 1–2 in Zonaria tournefortii.

Native to the Indian Ocean, S. schimperi was probably introduced into the Mediterranean through the Suez Canal. At present, it is distributed throughout the eastern Mediterranean.

These are unknown; however, this brown alga tolerates varied local conditions and has no known predators.
