Noctiluca Algae /Sea Tinkle

The Noctiluca algae, commonly known as sea tinkle, is a parasite and occurs in patches or ‘blooms’ in the Northern Arabian Sea.

They glow at night due bioluminescence (It is the production and emission of light by a living organism) and have earned them the nickname ‘sea sparkle’.

These patches are a sign of decline because they compete with fish for food and choke their supply.
