Which of the following fish is electric catfish?

What is the electric charge of a fish?

Torpedo is a marine cartilaginous fish which produces 8-220 volt electric charge (current) depending on species. Their electric organs are modified lateral muscle plates innervatted by carnrial nerves. Trygon (sting ray) resembles electric ray in many aspects but is devoid of electricity discharging (or producing) organs.

What is a marine cartilaginous fish?

>> A marine cartilaginous fish… The electric currents are produced by some species of fishes, such as the numbfish, Torpedo, etc. They produce electric discharge for communication, defense, and navigation. Was this answer helpful?

What is the electrical output of a fish called?

The electrical output of the organ is called the electric organ discharge, or EOD. EOD’s are typically functionally divided among electric fish. There are two types, pulse and wave, both originating from ancient evolutionary divergences in niche occupancy.

How many species of electric knifefish are there in the central Amazon?

“Chromosomal and electric signal diversity in three sympatric electric knifefish species (Gymnotus, Gymnotidae) from the Central Amazon Floodplain”. Reviews in Fish Biology and Fisheries. 22 (2): 485–497. doi: 10.1007/s11160-011-9239-1. ISSN 0960-3166. S2CID 7703678. ^ Bullock, Theodore Holmes; Heiligenberg, Walter, eds. (1986).

What is an electric current produced by a marine cartilaginous fish?

What is cartilaginous fish?

Cartilaginous fish, also called chondrichthyans, are characterized by having a cartilage skeleton. In addition, their skin is covered by placoid scales, which closely resemble a vertebrate tooth. That’s why these organisms have a rough texture to the touch.

How many volts does an electric fish have?

However, most electric fish are limited to between 8 and 40 volts. The two largest electric fish, The Electric Eel of South America and the Electric Catfish of Africa prey specifically on the smaller and weaker species of electric fish. They can turn off their own electrical field to help keep their presence unknown to their prey.

How much electricity does a fish generate?

This structure can generate up to one volt of electricity. An AA battery generates 1.5 volts of electricity. The electric field produced by electric organs travels about 1 metre around the fish. Weakly electric fish also have special cells in their skin. Electroreceptor cells help the fish sense changes in its own electric field.

Where can I find a weakly electrical knifefish?

The Weakly Electrical Knifefish of the Neotropical Area are found only in South America and Central America and not in Asia or Africa. There are many Weakly Electrical Knifefish including the Black Ghost, the Brown Ghost, and a few other that are kept by aquarists. Click here for more about Weakly Electrical Knifefish.

Are there electric knifefish in the central Amazon?

“Chromosomal and electric signal diversity in three sympatric electric knifefish species (Gymnotus, Gymnotidae) from the Central Amazon Floodplain”. Reviews in Fish Biology and Fisheries. 22 (2): 485–497. doi: 10.1007/s11160-011-9239-1.

How do animals generate electricity in the ocean?

Specialized yellow tissues absorb light and brown tissues generate the electricity. Sharks have receptors like some other animals on their snouts called ampullae of Lorenzini. Dolphins are born with whiskers attached to their snouts. They send electric fields in the ocean.

What animals use electricity to find their prey?

From the electric eel to the echidna, many animals rely on electric currents to communicate, find prey, and defend themselves. Electric eels (which are not true eels) can generate more than 800 volts to stun prey. An invisible force of nature, electricity is all around us.

Why do fish have cartilaginous skeletons?

However, they have a highly evolved cartilaginous skeleton which enables them to float better, swim faster, flex to catch prey and escape predators, bite wider and harder, grow bigger and heal more quickly.

Which of the following is a cartilaginous fish?

16. Most of the cartilaginous fishes are marine and most of them are predators. Scoliodon, Torpedo, Trygon and Chimaera. Rhinobatus (guitar fish) Pnstis, Zygaena, Carcharodon (Great White Shark). It is commonly called rabbit fish, rat fish, ghost fish or king of her rings.

Do cartilaginous fish have bone marrow?

The cartilaginous fishes do not have bone marrow (a semi-solid tissue found in the portion of bones), red blood cells are produced in the spleen (a particular tissue around the reproductive organ). These fishes have tough skin covered with dermal teeth, also called placoid scales.

What kind of fish is the African knifefish?

The African knifefish (Gymnarchus niloticus) lives in African rivers and it is related to the giant arapaima of the Amazon basin, the largest freshwater fish in the world, and the elephantfishes. It has a long and slender body, lacking caudal, ventral, and anal fins.

How big do knifefishes get?

6.The naked-back knifefishes (32 species of the genus Gymnotus species) are found in tropical America, from southern Mexico to northern Argentina, in different types of waters. The largest species can be 0.6 m (2 ft) long.

Are there any weakly electrical knifefish?

There are many Weakly Electrical Knifefish including the Black Ghost, the Brown Ghost, and a few other that are kept by aquarists. Click here for more about Weakly Electrical Knifefish.

Where can I find knifefish?

Weakly Electrical Knifefish The Weakly Electrical Knifefish of the Neotropical Area are found only in South America and Central America and not in Asia or Africa.

Where do South American knifefishes and electric eels live?

South American knifefishes and electric eels live in South America and Central America. South American knifefishes and electric eels live in small streams, large rivers, lakes, and various types of backwaters. Many of these fishes live in deep, main-river channels. Some live in water with low oxygen content and gulp air at the water surface.

Do knifefishes have electric discharges?

Knifefishes produce weak electrical discharges. South American knifefishes and electric eels live in South America and Central America. South American knifefishes and electric eels live in small streams, large rivers, lakes, and various types of backwaters. Many of these fishes live in deep, main-river channels.
