It is known, however, that liquids can only be slightly compressed under high pressure, but that gases are highly compressible. This means that animals with gas-filled structures, like the swim bladders of some fish, may be markedly affected by pressure change, whereas animals lacking these structures may be more tolerant of depth change. Air-breathing marine mammals, with gas-filled lungs, have evolved a variety of special anatomical and physiological adaptations that permit them to make deep dives.
Developed countries typically have monitoring programmes that permit the closure of contaminated shellfish beds (natural or cultivated) when toxins are detected in the water or in shellfish tissues; the incidence of sickness and fatalities from algal-derived shellfish poisoning is higher in coastal developing countries. A related health problem, ciguatera fish poisoning (or CFP) is found in tropical and subtropical countries, where certain species of toxic dinoflagellates five attached to seaweeds.
In shallow marginal seas, and coastal areas generally, the fluctuation in water temperature closely parallels air temperature, and annual variations may exceed 10°C. 58 50 surface maxima in shallow coastal waters average maximum surface temperature, Red Sea average surface temperature near Equator t) average minimum for survival of reef corals In addition to daily and seasonal variations in surface temperature, there are longer term climatic changes that affect marine ecology. Some of these events are deduced only from changes in seafloor sediments that suggest dramatic temperature changes in the overlying water during the geological past.
