Eichhornia crassipes is nick named as Terror of Bengal because it grows luxuriantly in eutrophic water bodies. Its excessive growth causes blocks in our water ways, leads to an imbalance in the ecosystem dynamics of water body. Its rate of excessive growth is higher than the rate of its removal- "Terror of Bengal" is the title given to this aquatic weed because initially it was introduced in water bodies of Bengal for its flowers and shape of leaves but however it turned out to be highly invasive water weed that not only spread in water bodies of Bengal but also throughout India.
