Sharks electroreception organ is called

The liver is a large and oily organ that comprises 25% of the total body weight of the shark. The two purposes of this organ in the shark are to store energy and oil. The liver is a hydrostatic organ. This organ helps with buoyancy since the liver stores oils, decreasing the density of the shark's body. The shark liver is also full of an oily-like substance called shark liver oil that helps the sharks be more buoyant and acts as an energy storer, where it can be utilized when needed.

A BIOLOGICAL FUNCTION FOR ELECTRORECEPTION IN SHARKS …

Ampullae of Lorenzini (singular Ampulla) are electroreceptors, sense organs able to detect electric fields. They form a network of mucus-filled pores in the skin of cartilaginous fish (sharks, rays, and chimaeras) and of basal bony fishes such as reedfish, sturgeon, and lungfish. They are associated with and evolved from the mechanosensory lateral line organs of early vertebrates. Most bony fi… WebbThe brain is probably flooded with the neurotransmitter called serotonin.
