The shores of Vaadho, Maldives resembles a sea of stars at night with the spectacular display of bluish-white glow aligning the sea shores. The bluish-white shimmers come from the luminescent plankton species that found on the shore waters. This shimmering shore seems to mirror the star-studded sky at night and one would definitely be lost in enchantment and magic upon seeing this phenomenon.
