Nature lovers and fisherfolks in Maharashtra are being treated to 'magical' sea for the past few days, with the water near the coast at few places turning blue at night and throwing up a greenish glow in the morning.

Experts say the colour show is due to bioluminescence, a phenomenon triggered by algal bloom. A Ratnagiri-based wildlife lover has recorded a video of green water, while many others have shared its photos on social media.
