All the animals that live emit electrical charges during routine muscle movement, although in most animals, weak electric issued. The animals that will be discussed below depend on the ability of their biological electroreception in producing electricity for hunting prey, predators and even against attacks navigation.
1. Peters Fish Elephant's Trunk
Found around river in west and central Africa, fish is dark. Rod-like protrusion of the head is a real mouth.
Elephantnose fish equipped with a special organ that produces electricity, which is located in the tail, which consists of thousands of "box-like multi-nucleated cells" called electroplax (or electroplaques).
According WetWebMedia.com, in the resting state, each electroplax cells have a negative charge and positive charge inside out. When organs are stimulated by muscle contraction, it will create a weak electrical current. Thus, Elephantnose fish is able to detect different levels of distortion, and then be able to distinguish between predators and prey.
2. Pari Electric Fish
Such as the electric eel, this animal, is able to control the voltage in any electrical charge in the body. Organ production is located on both sides of the head and together produce an electrical voltage to 220 volts. Electric shock produced almost similar to the effect when dropping hair dryer into the tub.
3. Hammer Head Shark
With hundreds of thousands of organs electrorecptor (called Ampullae of Lorenzini) in their bodies, this being the only shark shark has the greatest electrical sensitivity that can detect signals from half a billion volts of other animals. And make it easier to find prey.
Ampullae detect electrical fields generated by other animals underwater, making it possible to scan hammerheads and digging sand from the seabed dinner.Hammerhead sharks are also said to be on their internal detection such as GPS devices, helping to adjust to detect ocean currents moving in the magnetic field of the earth.
4. Echidnas
Including members of the order monotreme, spiny animals have elongated snout that serves as both the mouth and nose.The muzzle is also sending electrical signals that help them find insects for voraciously. Electroreceptive system at the muzzle is less complex than platypuses. Electroreception they proved useful despite them being land animals because they are constantly wet snout. It is much easier to conduct electricity in water than on land, which is why most animals with electroreception derived from water.
5. Electric Skate
These creatures spend most of their time on the sea floor (cold water), using electrosense their ability to take weak electric fields issued by the shrimp, snails and mussels their favorite. Their mouth is located at the bottom of their bodies, making it easier to find food. Each developed along the tail bilateral organ that produces intermittent electric shock. The intensity of the shock varies from species to species, but generally they are blessed with durability, allowing them to withstand quite a while. Although relying on themselves with electricity generated to fight predators, they also use it as a way to recognize and communicate with each other
6. Electric Eels
Most commonly found in the waters of South America, electric eels generate more electricity than any other animal in the world. With 5,000 to 6,000 electroplax! Research has shown that they can produce intermittent shock tirelessly for an hour. The amount of power generated can easily be deadly to humans average-sized adult. However, part of what makes an electric eel is unique is its ability to control the intensity of their shocks. Electric eels are not really classified as an eel, but more as a fish.
7. Electric Catfish
Freshwater catfish is native of tropical waters in Africa. With the ability to generate electricity up to 350 volts which is roughly the same amount needed to power a computer for 45 minutes.
