Looks like an Oil Spill but wait You might be wrong

Anchovy – the tiny, ubiquitous salt water fish of every sea of the world – is the staple of all marine predators and for human beings, literally the salt of the earth. In Asian cuisine, generally, the dried version is used in almost all savoury dishes and sauces as a condiment which eliminates use of salt! In European cuisine they are gutted and matured in brine and packed in salt or oil for sale.

It is very apt that the human eye perceives a school of anchovies as shifting streaks of oil slick because, among fish, they are classified as ‘oily fish’!
