Some adult invertebrates in tropical areas have relatively high MAA concentrations in external surfaces. Holothuroids preferentially accumulate MAAs in the epidermis, giant clams have highest concentrations of MAAs in the outermost layers of siphonal mantle tissue (more than four times the concentrations in subsurface mantle layers), sea hares have high MAA levels in skin, and ascidian tunics have higher MAA concentrations in the surface cells than in basal dermal lay-ers 102,152 154 jn coraiSj e upper exposed surface of colonies can have five-fold higher UV absorption than the less irradiated vertical faces.155 These topical distribution patterns reinforce the premise that MAAs have a photoprotective function.
