Description
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.

Dimensions & Sizes
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.

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.

What is the largest bony fish?
The largest bony fish is a female Mola alexandrine that was caught on the Japanese coast of Kamogwa, Chiba in 1996. The fish has a total weight of 2,300 kilograms and a height of 2.72 meters. It is currently the heaviest bony fish ever recorded in history.
When did bony fish first appear?
Bony fish first appeared between 530 to 410 million years ago during the Cambrian explosion. The first bony fish did not have jaws and had a primitive spinal column. It is believed that the first bony fish appeared along with the placoderms, who were the first jawed fish that evolved from their gill arches.
How do Osteichthyes reproduce?
Osteichthyes mostly reproduce through the sperm and eggs that are developed by male and female Osteichthyes. Some Osteichthyes are hermaphrodites and can produce both sperm and eggs. Male and female Osteichthyes may at times look similar or different due to their size, color, head characteristics, and overall body shape.

What do fish eat?
The diet of fish is very diverse as the number of fish species is very large. Some fish are carnivores, while other species of fish are herbivores or omnivores. Fish generally eat small organisms, algae, and sometimes can even eat other fish. The food that fish eat depends on their species, size, and environment.
How long do fish live?
The lifespan of a fish usually depends on the species. A fish may live anywhere between a year to 200 years – it all depends on the species of fish. The lifespan of a fish typically depends on their size, species, and whether they live in the wild or captivity.
How do fish sleep?
Fish do not sleep in the same form and manner that land mammals sleep. Fish sleep by reducing their activity and metabolism while remaining alert to any potential danger. While sleeping some fish float in place, in a secure spot within the mud, or find a nest. During sleep, fish perform restorative functions.

How are freshwater animals adapted to their environment?
Freshwater animals adapt to their environment through gills that obtain oxygen and allow them to live in rivers and streams in which the water is cooler and has a higher oxygen level. Freshwater animals also need to swim fast to catch food and utilize their environment to create their home.
Why are freshwater animals going extinct?
Freshwater animals are going extinct due to the creation of man-made elements that block migration routes for fish and disrupt habitats. The water withdrawal for human use also shrinks and degrades habitats as well as the draining of wetlands for development depletes habitats. Other reasons include overexploitation, pollution, and global warming.
How can we protect freshwater fish?
We can protect freshwater fish by establishing multiple solutions. These solutions include restricting the construction of dams and establishing protected wetlands. Other solutions to protect freshwater fish are regulating water withdrawal for human use and incentive for farming businesses to reduce the use of pesticides.

How do animals adapt to the coast?
Animals adapt to the coast by adjusting to living in salty water as well as being able to withstand being covered or uncovered by the tide. Further coastal adaptations also include being able to hide or escape quickly from predators, finding food, and staying in a safe place as the tides move.
Why are coasts important for wildlife?
Coasts are important for wildlife because they serve as nesting grounds for species of sea turtles as well as are habitats for animals like beach mice. Coasts are also important foraging areas for migratory shorebirds. Coasts are important as they are used in cohesion by all species of animals.
How does coastal erosion affect animals?
Coastal erosion affects animals and humans as it causes sea levels to rise, flooding, as well as stronger waves. Coastal erosion also causes the gradual loss of land that is important to many animals. Coastal erosion is when a portion of land is lost within a shoreline by either natural events or manmade decisions.

How do animals survive in estuaries?
Animals survive in estuaries by adapting to the harsh conditions of their habitat. Estuaries either have salt water or fresh water. Animals survive by adapting to live in the different types of conditions and remaining in the regions of the estuaries where they are most comfortable and have consistency.
Why do fish lay eggs in estuaries?
Fish lay eggs in estuaries because these habitats offer a great amount of food availability for the development of young fish while also providing protection from predators. Estuaries are often used as breeding grounds by many species of fish due to these factors and are considered highly valuable.
Why are estuaries important for birds?
Estuaries are important for birds because estuaries offer a mix of nutrients from both the land and sea, creating a rich ecosystem. Since estuaries house numerous species of fish, they also create a food source for birds. Birds also use the beaches next to estuaries for feeding, resting, and breeding.
