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. The … WebbElectroreception, is the biological ability to perceive electrical impulses. It is an ancient sense that has evolved independently across the animal kingdom in multiple groups …

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. When the brain is overloaded, the shark falls into a coma-like state. When the shark is in the right position the serotonin concentration decreases and the shark returns to consciousness. The second hypothesis is related to electroreception. WebbThe ampullae of Lorenzini give the shark electroreception. The ampullae consist of small clusters of electrically sensitive receptor cells positioned under the skin in the shark's head. These cells are connected to pores on … how do coffee beans grow
