Description:
|
C. taxifolia can adapt itself to different light conditions and is found in dense beds
down to 50 m depth. The growth curves as a function of water temperature show
an adaptation to alarge range of temperatures and a resistance to cold winter temperatures (3 months survival at 10°C). There is no connection between the development of C. taxifolia and water quality; it develops equally well in clean and
polluted waters. Caulerpa taxifolia synthesizes nine toxic substances, including caulerpenyne which is predominant. The percentage of toxins by dry weight in Caulerpa taxifolia is usually higher in the Mediterranean than in the tropical seas.
(lt has been shown that caulerpenyne in solution degrades rapidly in daylight
conditions, in the presence of oxygen and chlorophylls or phaeophytins). No caulerpenyne has been found to accumulate in sea urchins which have consumed Caulerpa taxifolia - and no toxicity risk to humans has been observed. Caulerpa taxifolia colonizes all types of sea bottoms, such as, rock, sand, mud and dead Posidonia meadows.
