Are Fish Head stones a mystery or design? Stones found in the head of Fishes for centuries have remain a mystery to the world.
The Fish Head Stones are called otoliths. Otoliths are calcium carbonate structures found in the heads of all fish species except sharks and rays, and are used for hearing and balance.
The calcium carbonate that the otolith is composed of is primarily derived from the water. As the otolith grows, new calcium carbonate crystals form. As with any crystal structure, lattice vacancies will exist during crystal formation allowing trace elements from the water to bind with the otolith.
There are various shapes and proportional sizes of otoliths with fish species. Flying fish have unusually large otoliths, possibly due to their need for balance when launching themselves out of the water to “fly” in the air. Often, the fish species can be identified from distinct morphological characteristics of an isolated otolith. Generally, fish from highly structured habitats such as reefs or rocky bottoms (e.g. snappers, groupers, many drums and croakers) will have larger otoliths than fish that spend most of their time swimming at high speed in straight lines in the open ocean (e.g. tuna, mackerel, dolphinfish).
Most farmed fishes are noticed to pocess little otoliths than the wild due to insufficient needy substances in the hydrosphere.

DID YOU KNOW?
Calcium carbonate is the active ingredient in agricultural lime and is created when calcium ions in hard water react with carbonate ions to create limescale. It is medicinally used as a calcium supplement or as an antacid( a substance which neutralizes stomach acidity and is used to relieve heartburn, indigestion or an upset stomach), but excessive consumption can be hazardous.
Fish Otoliths can be used to calculate the age of a fish.
