Toadfish. Splendid is implied but not guaranteed.
In December we ran into patches of very poor visibility at spots along Palancar Horseshoe and Palancar Gardens. This seemed clearly related to freshwater runoff from the island shore due to the very heavy rains - it was possible to see halocline-like optical distortion running in streams from the direction of shore. It seems very unlikely to be from mainland runoff, since that would be an awfully long way for freshwater to travel perpendicular to the prevailing currents without near-total dilution.
It seems very plausible that overgrowth of algae or cyanobacteria could occur in areas of abnormal salinity or concentration of contaminants from runoff, although I can't say I noticed any such areas nor that any show up in our photos.
