DAILY MAIL SCIENCE : SWIMMING DOLPHINS BIOLUMINESCENT GLOW

Excerpt: According to Mr. (Patrick) Coyne, the footage was challenging to film and required the perfect conditions - with bioluminescence being both difficult to spot and inherently short-lived in nature.

The glowing effect, often referred to as 'the fire of the sea', is produced by microscopic, single-celled organisms known as dinoflagellates, specifically those of the species Noctiluca scintillans.
