>>>Discover the secret of red tide

The expert group of the University of Connecticut (USA) has identified Alexandrium tamarense plankton containing not one but two types of toxins. In it, one has the ability to kill small predators; The other type is enough to take down other large creatures.

Red tide is more dangerous than we thought

'If it kills multicellular animals with a poison and unicellular organism with another poison, it is like an ocean killer , ' AFP quoted ocean expert Hans Dam.

The ability to kill both predators both large and small can lead to disruption in the sea food net during the "red tide" spreads, similar to what happened in the northeastern US coast in the year. 2005.

Alexandrium in a small amount is usually harmless to humans, but if they are absorbed by marine organisms such as boys, oysters, or crustaceans, the poison will be added and raised. to the point of causing danger to people.

In some parts of the world, just eating poisoned shrimp and crab meat is enough to get sick or even worse than death.

'The magic is that when you look at algae through a microscope, they are beautiful. But death is no less, " Dam said, which is why scientists call them " beautiful assassins ".
