Red tide is a phenomena that is caused by algal bloom specifically due to the growth and abundance of unicellular algae called as dinoflagellates and diatoms. These organisms impart red color to the coastal waters. Such kind of algal blooms release toxins in the water. They deplete the concentration of oxygen in the water body.
