3 Incredible Moray Eel Facts!
• Razor teeth: The moray eel is a fish that has two jaws filled with very sharp teeth. The bite of this fish can pierce the skin of a human.
• Excellent smell: These eels have small eyes along with poor vision. Fortunately, they have an excellent sense of smell which helps them to find prey in the dark ocean waters at night.
• Baring its teeth: Moray eels are fish that are thought of as aggressive because they seem to be baring their teeth at all times. But this fish must keep its mouth partially open so it can breathe.
Moray Eel Classification and Scientific Name
The scientific name for the moray eel is Muraena retifera. It is sometimes called a reticulate moray. The word moray derives from the Greek word muraina, which means a type of eel.
It belongs to the Muraenidae family and the class Osteichthyes.
There are 220 species that fall within 16 genera. These genera are divided into 2 subfamilies called Muraeninae and Uropterygiinae.
Moray Eel Species
There are 220 species of eel belonging to the Muraenidae family. The majority of these species live in saltwater. Some of the most notable examples include:
• Giant moray eel: This is the largest of the species. They grow to be about 10 feet long and weigh around 66lbs. They can be found living in coral reefs in the Indo-Pacific Ocean region.
• Green moray eel: Despite its name, its skin is brown. This eel has mucus all over its body that prevents parasites from latching on. The mucus makes its skin appear green. These fish live in the western Atlantic region.
• Mediterranean moray: This fish is also known as the Roman moray. Its range includes the Mediterranean Sea and the eastern Atlantic Ocean.
• Honeycomb moray eel: It’s sometimes called the leopard eel because of the pattern of black spots on its skin. It lives in the Indo-Pacific Ocean region and is one of the eels living on the Great Barrier Reef.
Moray Eel Appearance
The color of this creature depends on its species. Some have smooth skin that’s brown or gray. Others are colorful like the green moray eel or the ribbon eel. Blue, white, and orange are other colors seen on this species of fish.
These fish have two jaws with rows of prominent sharp teeth. They have a dorsal fin just behind their head along with tail and anal fins. Also, they have small eyes atop a long nose.
A moray eel can measure from 1 to 13 feet in length depending on its species. The smallest size is the dwarf, which makes its home off the coast of Hawaii. It grows to be just 1 foot long. The longest species is the slender moray eel at 13 feet long.
There’s a wide weight range for this family of fish. For instance, the Hawaiian dwarf weighs just a few ounces whereas the heaviest species, the Giant, weighs 66 pounds.
A giant Conger eel is the largest ever caught by fisherman. It measured 21 feet and weighed 131 pounds!
This creature’s teeth are one of its most effective defensive features. Many of the larger species can cause great injury with their bite. The poison contained in an eel’s skin is another defensive feature.
Moray Eel Distribution, Population and Habitat
The various species live in ocean waters that are tropical or temperate. They live in oceans all over the world. As one example, a green moray eel lives in the Atlantic Ocean near the Florida Keys and the Bahamas. The giant moray eel lives in the Indo-Pacific Ocean region and are seen near Africa’s eastern coast.
These fish can move into shallow water or swim 600 feet down into the ocean. Their habitat includes coral reefs and caves. Many species live on the Great Barrier Reef near the Queensland coast of Australia. The green, giant and slender moray eels are just a sampling of the hundreds of species on the Great Barrier Reef.
The conservation status of these creatures is Least Concern. According to the IUCN Red List of Threatened Species, the population is unknown. One reason why the population is unknown is because these eels are elusive and remain hidden in coral reefs and in rock crevices most of the time. They are also nocturnal, which makes them difficult to see.
Moray Eel Predators and Prey
The conservation status is Least Concern. However, these fish are threatened by increased water pollution. Also, these eels are captured and eaten in some countries including Germany, Poland, Sweden, and Denmark.
Moray Eel Reproduction and Lifespan
Reproduction takes place in January and February. These creatures achieve sexual maturity at 2.5 years old. A female releases around 10,000 eggs and they are fertilized by a male’s sperm. So, reproduction happens outside a female’s womb. When the eggs hatch, the larvae float along in the open ocean. After a year of growth, the larvae are strong enough to swim into the depths of the ocean to hide.
The lifespan of a moray eel ranges from 10 to 40 years.
Moray Eel in Fishing and Cooking
Moray eels are not targets of commercial fishermen. But they are sometimes unintentionally caught in commercial fishing nets.
There is a risk in eating moray eel. It can cause ciguatera poisoning. They carry this poison in their skin and it’s possible that it remains in the fish even after it’s cooked. A person who ingests this poison becomes very ill. But, despite the risk of ciguatera poisoning, this fish is a delicacy in some countries including Germany, Poland, Sweden, and Denmark.
The number of moray eels caught each year is unknown.View all 46 animals that start with M
