Deep-water marine organisms, metabolites

In summary, as far as it can be presently understood, there is little peculiarity as to the secondary metabolites of deep-water marine organisms, except, perhaps, the free porphyrins of medusae and sponges an adaptive role of sensors in the absence of light may be suggested for them. The secondary metabolism - mostly unexceptional in the global perspective of marine organisms - seems to be more related to the range of the species - a composite of many factors - than to any effect clearly attributable to the hydrostatic pressure.
