Many organisms inhabiting shallow-water or inter-tidal marine environments are protected from long-term solar damage by producing natural, UV-absorbing sunscreens of the generic class known as mycosporine amino acids (MAAs) (Dunlap et al. 1986) These compounds are derived from the shikimic acid pathway (Bently 1990) via 3-dehydroquinic acid and 4-deoxygadusol (4-DG). Mycopsorines were first discovered in terrestrial fungi (Favre-Bonvin et al. 1976) and these metabolites are believed to provide UV protection to fungal spores while exposed to solar radiation during atmospheric dispersal (Young and Patterson 1982).
