Eels | Anguilliformes

Eels are usually bony fish or ray-finned fish grouped under order Anguilliformes. These animals are nocturnal, predators, migrate, and most species lack scales. Eels are elongated fish that lack the pelvic and pectoral fins with the dorsal and anal fins fused to form a single ribbon that runs along the entire length of the body of the animal. The Eel can swim forward and backward and you will spot them living in shallow waters of both fresh and salty water, burrowing into the sand, rocks, and mud. They too are a wonderful source of food.

Where do eels live?

Eels live in both freshwater and saltwater bodies of water, but the majority of the species typically live at sea. The habitat of eels generally consists of shallow waters as they prefer to burrow into the sand, mud, or rocks. Some species of eels are more at home within the continental shelves.

What do eels eat?

Typically, eels eat a variety of fish, crustaceans, and mollusks. Eels generally follow a carnivorous diet. Eels can eat almost any marine creature that is smaller than they are thus creating a diverse diet. The diet of eels is made up of sea urchins, crabs, shrimp, lobsters, frogs, krill, worms, and clams.

How do eels reproduce?

Eels reproduce through the process of external fertilization as the female eel release millions of eggs into the water to be fertilized by the male’s sperm. Eels, unfortunately, die after the reproduction and mating process. The reproduction process of eels has been considered a mystery for years.

Fimbriated Moray (Gymnothorax fimbriatus)
Scale illustration of an average Fimbriated Moray compared to a human and other eel species

Instead of swimming, the Fimbriated moray(Gymnothorax fimbriatus) will move in a snake-like fashion, made possible by its serpent-like body dotted in black spots. The fish falls under the family Muraenidae and also goes by the names spot-face moray and dark-spotted moray. This mysterious creature lacks pectoral and pelvic fins, prefers lagoons, harbors, top reefs, and coral reefs of Indo-Pacific waters hiding in holes and crevices with other morays. Other features of the fimbriated moray include white dressing on the mouth, a head with a tapered snout, acute perception, and sharp teeth. Besides being carnivorous, it also shows hermaphroditism or intersex.

Fimbriated Morays have a total length between 31”-37” (79-94 cm) and body height of 2.4”-3.1” (6-8 cm). The typical weight of the Fimbriated Moray is in the range of 2.2-4.4 lb (1-2 kg). Fimbriated Morays have lifespans between 10-30 years.

Slender Snipe Eel (Nemichthys scolopaceus)
Dimensioned comparison drawing of the Slender Snipe Eel compared to an average person and other eels

Until you take a closer look, you may assume the slender snipe eel (Nemichthys scolopaceus) as a ribbon or string because of its thin body resembling a thread. The fish is cataloged under the family Nemichthyidae with bird-like beak spotting curving tips which help it easily capture food. This true eel is light-weight, nocturnal, with eyes larger than its body size, and populates the bathypelagic and mesopelagic zones besides being the only creature with a backbone having more vertebrae. Its bird beak bore it the name deep-sea duck, and its anas evolved to the degree of being adjacent to the throat.

Slender Snipe Eels have a total length between 51”-79” (1.3-2 m0 and body height of 1”-1.6” (2.5-4 cm). The typical weight of the Slender Snipe Eel is in the range of .4-.5 lb (.17-.23 kg). Slender Snipe Eels have lifespans between 7-10 years.

Zebra Moray (Gymnomuraena zebra)
Dimensioned comparison drawing of the Zebra Moray compared to an average person and other eels

The heavily banded dark and white color gives the Zebra moray (Gymnomuraena zebra) a ‘zebra' motif. Aside from being prevalent throughout Indo-Pacific zones, it is also fit for community fish tanks as it no threat to aquarists and other tank dwellers. The Zebra Moray belongs to the family Muraenidae and possesses an elliptical but short snout, a flat and plate-like dental formula for crushing hard shells unlike for other morays that are pointed. Like most morays, it loves rocks and coral reefs of shallow water, nocturnal, shy, and reclusive predators compared to other morays and rarely aggressive unless bullied.

Zebra Morays have a total length between 20”-59” (51-150 cm) and body height of 1.2”-3.5” (3-9 cm). Zebra Morays have lifespans between 10-20 years.

European Conger (Conger conger)
Comparison illustration of the size of a European Conger to other eels and a typical person

The largest eel on the planet, the European conger (Conger conger) reproduces once in its life. The European Conger is a nocturnal predator possessing a lengthy body without scales and is national to the European coastline, specifically Northeast Atlantic and the Mediterranean Sea. Juveniles love coastal areas while adults prefer deeper waters. The European conger’s conical head, slightly reduced rounded snout and merged dorsal and anal fins enable it to hide effortlessly under rocks and cracks. The fish is a representative of the family Congridae and undergoes metamorphosis in its reproductive organs, skeleton mass, and teeth between the ages of 5 to 15 years.

European Congers have a total length between 60”-84” (1.52-2.13 m) and body height of 3.1”-4.7” (8-12 cm). The typical weight of the European Conger is in the range of 6.6-55 lb (3-25 kg). European Congers have lifespans between 15-20 years.

European Eel (Anguilla anguilla)
Dimensioned comparison drawing of the European Eel compared to an average person and other eels

The European eel (Anguilla Anguilla) may be the only nomadic fish among the eel because of the tremendous trip it makes from Europe to Bermuda to spawn. Not only that, but it also shows different life stages: glass eel, Elver, Yellow eel, and Silver eel, each taking place in varied habitats. Like other eels, it possesses a snake-like body, one pair of small pectoral fin, secretive and nocturnal, preferring under rocks, and burrowing into the mud. This catadromous fish belongs to the family Anguillidae, native to the European coast from Russia to Morocco, and is a well-known powerful swimmer and climber.

European Eels have a total length between 24”-39” (61-99 cm) and body height of 1.6”-2.75” (4-7 cm). The typical weight of the European Eel is in the range of 3-8 lb (1.4-3.6 kg). European Eels have lifespans between 15-20 years.
