What is special about Sargasso Sea?
While there are many different types of algae found floating in the ocean all around world, the Sargasso Sea is unique in that it harbors species of sargassum that are ‘holopelagic’ — this means that the algae not only freely floats around the ocean, but it reproduces vegetatively on the high seas.
What happens in the Sargasso Sea?
Although the Sargasso Sea remains calm with its surrounding currents, a subtropical gyre is formed here. As a result the entire sea area with its mat like weeds slowly rotates clockwise. However, the rotation and its speed also depends on the surrounding weather conditions.

Why is the Sargasso Sea so salty?
The higher salinity of Sargasso Sea is attributed to high temperature and greater evaporation and lack of mixture of fresh water by rivers or ice water.
Is sargassum toxic to humans?
Decomposing Sargassum releases hydrogen sulfide gas and ammonia, which can cause respiratory, skin and neurocognitive symptoms in both local residents and tourists. Toxic exposure typically happens during decomposition, which is about 48 hours after it washes ashore.
What is the richest sea on Earth?
Mediterranean. The deepest waters of the Mediterranean were thought to be sparsely populated, but the Census of Marine Life says life is abundant there.
What lives in the Sargasso Sea?
