Blog 10 - Algal Bloom Leads to Manatee Deaths

     Since I have focused most of my research on the Red Tide algae blooms this semester, this was an article I came across. For those of you who don’t know, The Red Tide Algae is a toxic bloom that occurs mainly in the Gulf of Mexico, it is pretty harmless to humans, but it is known for killing massive amounts of sea life. What I didn’t know, is that manatees are suffering greatly from it.



     Manatees are already an endangered species. There are only 5,000 manatees in the Floridian waters and 241 manatees have been killed because of these algae. Experts say the numbers are surely to rise. The dino flagellate microbes that make up the red tide live in warm waters, as do manatees, and the water in Florida is the place for that. Even though the numbers of red algae has dissipated, the toxins from it still live on the grasses and seaweed in the water, and manatees can eat 100 pounds of grass daily.

    Scientists are still puzzled to see why the toxin levels are so high. The brevetoxins can kill mammals, birds, aquatic life, and there have even been cases of respiratory problems in humans. Some think that the mild winters helped the algae live longer. “So far this year, at least 463 manatees have died from a range of causes, more deaths than had been recorded previously” (April 6, 2013). Most deaths tied to poison.

   
     This article was shocking. I couldn’t believe how many manatees have died from the brevetoxins, and scientists still don’t know what to about it. It contained a bunch of information about the problem, and was very well written. I didn’t find any information on this year’s death rates, but hopefully it has gone down, and scientists are coming up with ideas to help stop this problem.
