Eels are characterized by their elongated, wormlike bodies. Unlike most fish, eels do not have pelvic fins, and most species do not have pectoral fins. Eels have a continuous dorsal, anal, and caudal fin that runs around the tail tip. To swim, eels generate waves that travel the length of their bodies.
What are 3 interesting facts about eels?
Let’s find out as we examine these 9 slithery facts about eels:
- Eels are covered with slimy mucus.
- Eels have horrible eyesight.
- Eels weigh between 95 gm to 215 gm.
- Eels can measure between 5 to 13 feet in length.
- Eels can swim backwards and forwards.
- An eel can live for up to 85 years.
What are eels known for?
Eels swim by generating waves which travel the length of their bodies. They can swim backwards by reversing the direction of the wave. Most eels live in the shallow waters of the ocean and burrow into sand, mud, or amongst rocks. A majority of eel species are nocturnal, thus are rarely seen.
What’s weird about eels?
Eels are philosophically and scientifically slippery. They’re fish that can survive for several hours on land, they can live for 85 years, and they don’t have sex until the last year of their life. Even after centuries of study, they’re still among of the most mysterious creatures on the planet.
What abilities do eels have?
Lightning in the Dark. Electric eels have thousands of special cells, called electrocytes, that can store energy like a battery and then discharge it. When an eel hunts, it uses this high-voltage charge to disable the muscles of a fish, similar to the effects of a Taser gun, before sucking the fish into its mouth.
Do eels have hearts?
The eel heart consists of four chambers placed in series: a sinus venosus, a thin-walled atrium, a more muscular ventricle and an outflow tract (bulbus arteriosus) (Fig. 1).
Do eels have poor eyesight?
Electric eels are nocturnal, live in muddy, dark waters, and have poor eyesight. So instead of using eyes, electric eels emit a weak electric signal, which they use like radar to navigate, to find a mate, and to find prey.
What happens if an eel bites you?
Moray eels aren’t poisonous — the most common complication from a moray eel bite is infection. More serious bites may require stitches, and some can cause long-term injury like the loss of a digit or body part. Try to avoid spending too much time near known eel habitats and keep your distance if you spot one.
Are eels poisonous?
Eels’ blood is poisonous, which discourages other creatures from eating them. A very small amount of eel blood is enough to kill a person, so raw eel should never be eaten. Their blood contains a toxic protein that cramps muscles, including the most important one, the heart.
Do eels bite humans?
“Eel attacks are quite rare. Basically, eels aren’t aggressive to humans,” he said. “If they feel trapped or if a human sticks their foot down in a hole, they may defensively bite.”
Are eels asexual?
Cooke adds that the leading theory of eel reproduction is that they reproduce by external fertilization, in which clouds of sperm fertilize free-floating eggs.
Is eel a fish or snake?
Eels are actually fish (albeit typically longer) and are flatter than snakes. As marine animals and unlike reptiles, eels breathe underwater with their gills and fins, and therefore cannot survive outside of water.
What is the lifespan of an eel?
The average life expectancy for the species is usually 10 to 20 years, though one specimen named Pute lived in an aquarium for 85 years, aquatic scientist and eel expert William O’Connor told NBC News.
Do eels sleep?
Electric eels live in fresh water. They are nocturnal, which means they sleep during the day and are active at night.
Are eels strong?
Researchers have named a new species of eel that can produce an electric shock up to 860 volts. Say hello to two new species of electric eel, including one that can discharge up to 860 volts, the strongest of any known animal, researchers say. Electric eels send out an electrical discharge to stun prey.
Do eels really have electricity?
Electric eels – actually a type of knifefish, not true eels – are notorious for being able to produce a hefty electric shock of up to around 600V. The source of their power is a battery-like array of cells known as electrocytes, which make up around 80 per cent of the eel’s metre-long body.
Do eels have a brain in their tail?
Eel myth 1: Their brain is in their tail. Sorry. Nor is the tail where all their nerves end. Eels keep their brains in their heads and their nerve endings wherever they need sensation.
Do eels eat each other?
Most eels don’t eat other eels, but some will. Some eels move back and forth between fresh water and ocean environments. In these varying environments, eels may select from a wider range of food items, including mosquito larvae and worms.
What animal eats eels?

- Eels.
- Raccoons.
- Storks.
- Eagles.
- Osprey.
- Sea snakes.

Can eels hear?
Summary. The auditory sensitivity in the European eel (Anguilla anguilla) was measured using an acoustic tube producing sound stimuli with different ratios between sound pressure and particle motion. The upper audible frequency limit in the eel was about 300 Hz.
Do eels have bones?
The meat of the eel has a distinctive and beautifully clean flavour. And eels make easy eating, because they have just one bone running down the middle, so they’re not finicky things. On the preparation side, most recipes call for the creature to be skinned.
