(400–700 nm, 1-nm intervals) of 12 basic reef bottom-types in the Atlantic, Pacific, and Indian Oceans: fleshy (1) brown, (2) green, and (3) red algae; non-fleshy (4) encrusting calcareous and (5) turf algae; (6) bleached, (7) blue, and (8) brown hermatypic coral; (9)...
The vast ocean may seem empty at times, but it is teeming with life. In addition to microbes, algae, and marine plants, sea animals occupy every ecological niche. Scientists don't have an exact count of sea animal species, but the ones they have identified are diverse. They range in siz...
While clams are available all year round, it is recommended to only eat them during the “R” months (September-April) as shellfish can absorb toxins that are spread by “red tides”. Red tides come about in the summer months and are caused by algae, which produces toxins that make it...
They also affect green algae by interfering with photosynthesis. It also causes reproductive issues and impairs the nervous system of sea urchins. In dolphins, mussels and other fish, it causes fertility issues and accumulates in their tissues, affecting their growth. ...
