The exclusively marine sea life creatures are the moray eel that are found only in salt waters. Some of them are also grow in brackish waters too. Moray eel belongs to the eel family and the largest among them is the green moray eel.
The eels have an extended dorsal fin. This shapes like a tail by joining with caudal and anal fins. The eels do not have pectoral and pelvic fins. They usually have small eyes which makes the sight of the eels difficult. So they use their sense of smell to identify their prey. They also have a protruding snout with wide jaws. They have narrow heads which helps the eels in swallowing the prey. The moray eels have another set of jaw inside the mouth that helps in capturing and restraining its prey. These pharyngeal jaws also have teeth that help in wounding the prey.
They also have a protective layer of mucus over its body surface which is secreted by them. This layer protects the eels from any bacterial attacks inside the water. The skin will not have scales. This gives a smooth appearance. The body of the eel ends with a short tail fin.
They have a unique character among the sea life creatures which is team hunting. The moray eels initially select the team by analyzing the capacity of the team mates in entering into crevices which are narrow. When the team is formed, a confirmation is made by the eels by shaking the heads. The eels then make a hunt as a team by surrounding the prey in all directions and finally killing it. Such co-ordinated activities are not seen in any other type of fish.
Habitat of Moray Eels
They can be found in tropical and temperate climates. They are found in oceans and sees of the tropical regions. Usually the moray eels live deep inside the water. They are highly conservative in nature. They hide them inside crevices and behind the rocks. Most of the moray eels live in salt water only. Some can be found in brackish water bodies. Certain species like fresh water moray eels are found in fresh waters. They can travel to some sub-tropical regions at times. A little population of these eels are seen in other parts of the world too.
Moray Eel and Humans
These sea creatures have got the capacity to wound humans. They have sharp teeth that can pierce human body. But they do not feed on humans. They feed only on other small fishes. Most of the time, these eels are thought to be highly viguous. In nature they are shy and conservative. They do not harm humans wilfully. Any attack on humans is purely for defense. If there is any misconception of prey, the eels can hurt humans.
Otherwise, the moray eels always try to flee rather than fighting with humans. They are completely harmless to human beings. There are divers who feed these animals with food and there are chances of the divers being harmed by the eels. But usually these eels hide from humans behind crevices and rocks.
They can be found along the seas of Canada, USA, Mexico, Brazil, Atlantic and eastern Pacific regions. They will be found abundant in rocky shores, and near the reefs and mangroves.
