Introduction: What are the types of Eels?

What are the types of Eels? – Eel is a fish with ray-like fins that is in the same family as true eels (Anguillidae). The species is a fish that moves from fresh water to salt water and back again.

There are around 800 species of eels, divided into eight suborders, 19 families, and 111 genera.

Carlo Mondini, an Italian, found an eel’s ovaries in 1777. This proved that eels are a type of fish. (see article on Wikipedia)

Half Banded Spiny Eels are a strange addition to the peaceful community of softwater fish. The bottom of the aquarium should be soft sand so that these diggers can bury themselves. There should also be lots of places for them to hide, like thickets of plants, bogwood, caves, pipes, and so on.

Japanese Eel

Japanese eel is so valuable that it’s called “white gold,” but its value on the black market has made it an endangered species, and scientists still don’t know how it reproduces. (source: scmp.com)

As of 2006, the Peacock eel has never been seen to have babies in an aquarium. It can be hard to tell the difference between a male and a female Peacock eel, but an adult female will have a rounder body.

Pelican Eel

Ribbon Eel

Black Phase (Juvenile): Ribbon eels start out as juveniles, which are easy to spot because their bright yellow dorsal fin runs the length of their dark, black bodies.

Blue Phase (male): As the eel grows up, its black color changes to a bright, electric blue, and its yellow dorsal fin gets even brighter. This is the male stage of the ribbon eel’s life cycle.

Yellow Phase (Female): As the male ribbon eel continues to grow, its color changes again, this time to yellow. When the ribbon eel reaches about 1.3 meters (4 feet), it enters its female stage. Ribbon eels that are in the female stage can lay eggs. The Samoa sawtooth eel, Serrivomer samoensis, is a sawtooth eel in the genus Serrivomer. It lives between 500 and 2,000 m deep in the south-west Pacific.

The Samoa sawtooth eel, Serrivomer samoensis, is a sawtooth eel in the genus Serrivomer. It lives between 500 and 2,000 m deep in the south-west Pacific.

Like other sawtooth eels, the eel has long, thin, and narrow jaws with protruding teeth that are falciform and point backward. This helps the eel eat big animals.

Short-finned Eel

Almost 7000 years ago, people in the Lake Condah area of southwest Victoria fished for Southern Shortfin Eels in fresh water.

With diversion channels, weirs, and stone eel traps, the Gunditjmara people, who were native to Australia, changed the landscape to set up a very sophisticated aquaculture industry.

Large groups of Aboriginal people lived in this old volcanic landscape all year long. They farmed, smoked, and traded eels there. The Budj Bim Cultural Landscape is now on the list of World Heritage Sites for 2019.

Slender Giant Moray Eel

The giant moray is found all over the Indo-Pacific, from the eastern coast of Africa, which includes the Red Sea, to the Pitcairn group, the Hawaiian islands, and Polynesia. From north to south, it goes from Japan to New Caledonia, Fiji, and the Austral Islands in the south.

Snake Eel

Snake eels are not a single species, but rather a group of more than 300 different kinds of eels. The scientific name for this family is Ophichthidae, but most people call them worm or snake eels. Most of the time, eels live in warm, tropical waters. Most species live and hide in things at the bottom of rivers or the ocean. Depending on the species, snake eels come in a wide range of sizes, with some getting as long as 10 feet (about 3 meters).

Snipe Eel

The upper and lower jaws of a snipe eel are very long and bend away from each other at the ends. This means that when the eel shuts its mouth, they don’t touch. The eel can catch its food with the help of its curved jaws. The jaws are full of tiny hook-like teeth that help catch shrimp and other small crustaceans.

The snowflake moray eel has been seen slithering onto the beach to catch a tasty crab. That doesn’t happen all that often, since some fish come out of the water to eat. But the snowflake does leave behind the water. Unlike other fish, it doesn’t have to swallow water with its food to help it go down.

Snyder’s Moray Eel

Snyder’s moray (Anarchias leucurus) was first seen by Snyder in 1904. He gave it its name. Because it has small spots on its body, some people call it a fine-spotted moray or a fine-spot moray. It is the smallest moray and is made up of several different kinds of eels.

There are a few different kinds of spiny eels that are sometimes called “track eels.” Track eels may also be called zig zag eels or white spotted spiny eels. They live in India, Thailand, and Myanmar, which are all in Southeast Asia. Most of the time, they live alone and are most active at night.

This eel lives in Southeast Asian rivers and swamps. People with big freshwater aquariums often keep them as pets. This carnivorous eel can grow up to 2.4 feet long when it’s fully grown.

Zebra Moray Eel

Zebra Moray Eel
Zebra Moray Eel – megaquarium.fandom.com

The Zebra Moray lives in the Indo-Pacific and is one of the few moray eels that doesn’t eat fish. This makes it the moray species that would do best in a tank with other fish. But it will eat things that are not animals.

Like other morays, the Zebra Moray needs lots of rocks and caves to hide in so it can feel safe. To keep both the aquarist and the eel from getting hurt, it should be fed with a soft-tipped feeding stick, like those sold for pet snakes.
