What is the difference between a fire eel and a conger?
The conger and muraena have powerful jaws with sharp teeth strong enough to drag people, while several shocks from an electric eel can cause respiratory or heart failure in people with underlying heart issues. The fire eel has toxic skin. Different species vary in appearance by their length, color, mouth, and fins.
Is a fire eel a fish?
The fire eel is not a true eel, but an extremely elongated fish with a distinctive pointed snout and underslung mouth. It is part of a group of fishes called spiny eels that also includes tire track and peacock eels.
Can you keep two Fire eels in the same tank?
You should never keep two fire eels together in the same tank as they start fighting with one another. They want to take control of the territory where they stay; therefore, they don’t like to share it with another of their same kind.
Can electric eels be kept as pets?
These fish have always been sought after by some animal collectors. Keeping electric eels in captivity is difficult and mostly limited to zoos and aquaria, although a few hobbyists have kept them as pets. The Tennessee Aquarium in the United States is home to an electric eel.
What makes the electric eel so dangerous?
The electric eel is unique among the Gymnotiformes in having large electric organs that can produce potentially lethal discharges that allow them to stun prey. Larger voltages have been reported, but the typical output is sufficient to stun or deter virtually any animal.
How do eels breathe in the ocean?
E. electricus has a vascularized respiratory system with gas exchange occurring through epithelial tissue in its buccal cavity. As obligate air-breathers, electric eels must rise to the surface every ten minutes or so to inhale before returning to the bottom.
How does an eel conduct electricity?
When an eel is totally submerged the current is conducted by the water, closing the loop. The eel can make the shock more intense by leaping out of the water and making the electricity travel through the body of the attacker to reach the negative pole.
Why do eels burrow in the sand?
They have much thicker skin and high densities of goblet cells in the epidermis that allows mucus to be produced at a higher rate than in other eel species. This allows sand granules to adhere to the sides of their burrows in sand-dwelling morays, thus making the walls of the burrow more permanent due to the glycosylation of mucins in mucus.
Are electric eels air-breathers?
Electric eels are also air-breathers, meaning they need to surface about every ten minutes to breathe (as opposed to true eels, who can breathe underwater with gills). What makes electric eels stand out is (no surprise) their…electricity.
How does an electric eel Find You?
As you soon as you enter the water, the fish will let out an electric discharge. It does this by using the three electric organs within its body. These organs contain electrolytes and the eel uses them to navigate and communicate as well as shock it’s prey. The first electric shock is used to locate you.
Can you keep an electric eel in captivity?
Keeping electric eels in captivity is difficult and mostly limited to zoos and aquaria, although a few hobbyists have kept them as pets. The Tennessee Aquarium in the United States is home to an electric eel.
How do electric eels see in muddy water?
Electric eels have a series of electricity-generating cells which pulse and create an electric field around them. If anything comes into this field, it bounces back a signal to the eel. That allows it to build up a map of its surroundings. So it can see even in muddy water!
Do eels have any enemies?
People eat eels, too, and sometimes set traps for them. But the largest of eels, such as the moray, have very few natural enemies because most creatures are afraid of them. As for the question of what an eel eats—most eels eat other fish and crustaceans.
What is a European eel?
European eels are fish with one pair of small pectoral fins and long, snake-like bodies. As catadromous fish, European eels spend most of their adult lives in freshwater rivers, streams, and estuaries before returning to the open ocean to spawn and lay eggs. As young larvae, baby eels drift around the sea for between seven months and three years.
Do ribbon eels live in coral reefs?
Ribbon eels are found predominantly on healthy coral reefs but they also seem to thrive on damaged reefs too where the bottom composition is mainly sand and rubble. Usually it is only the ribbon eels head and upper body that are visible as they live burrow in the sand and hide under rocks and in crevices.
What is a sand eel?
“Sand Eel” actually covers a whole load of different small fish species, all in the Sand Lance family. They are distinctively slender with a pointed snout – giving them an eel-like shape. Between April and September they swim in large shoals close to the seabed and will burrow into the sand to escape predators.
What are the different classifications of eels?
A number of classifications of eels exist; some, such as FishBase, divide eels into 20 families, whereas other classifications such as ITIS and Systema Naturae 2000 include additional eel families, which are noted below the family with which they are synonymized in the FishBase system.
How do fish breathe water?
Fish can breathe the water by swimming forwards and letting some of the passing water flow in through the mouth, across the gills, and then out. They can control the amount of blood flowing through their gills, increasing the amount of oxygen they take from the water if they are being more active.
How do electric eels shock their prey?
Not only can electric eels shock their prey directly, but they have also refined their electrical system to the point that they can use the signals to navigate and communicate. They can even get their prey to reveal themselves no matter how well hidden!
Why do South American eels have low voltages?
They can also produce lower voltages (less than 1 V) for navigation and communication. If the first shock doesn’t wear out its prey, South American eels can twist around and trap its prey and release a volley of electric charges.
What is the anatomy of an electric eel?
Anatomy. The electric eel has an elongated, cylindrical body, typically growing to about 2 m (6 ft 7 in) in length, and 20 kg (44 lb) in weight, making them the largest species of the Gymnotiformes. Their coloration is dark gray-brown on the back and yellow or orange on the belly. Mature females have a darker color on the abdomen.
Do eels have a sense of direction?
Electric eels, gymnotid eels, knife fishes, and momyrids create electrical fields and can sense their way without any light. Almost all fish have a lateral line, a series of sensory pores along the length of the body that sense pressure waves.
How long can you keep an eel as a pet?
They breathe mostly atmospheric air, as they have a rather sophisticated lung-like organ. You can own this boring eel as your pet for about 18 years with proper care. There are general similarities between all the eel fish, that need to be taken into consideration.
Can an electric eel breed in captivity?
It’s not been bred in captivity. Apparently the eggs are deposited in a nest built by the male, using his saliva! One of the most notorious fish in the world, the electric eel is a truly fascinating species.
How do fish navigate in muddy water?
Much of the aquatic world is not clear water, however, so fish have plenty of other sensory adaptations that let them navigate in muddy water. Some fish create an electrical field around themselves.
What kind of fish is a European eel?
European eel. The European eel (Anguilla anguilla) is a species of eel, a snake-like, catadromous fish. They can reach a length of 1.5 m (4 ft 11 in) in exceptional cases, but are normally around 60–80 cm (2.0–2.6 ft), and rarely reach more than 1 m (3 ft 3 in).
What is the conservation status of European eels?
Conservation status. The European eel is a critically endangered species. Since the 1970s, the numbers of eels reaching Europe is thought to have declined by around 90% (possibly even 98%). Contributing factors include overfishing, parasites such as Anguillicola crassus, barriers to migration such as hydroelectric dams,…
