Moon Fish Interesting Facts
What type of animal is a moon fish?
Moon fish belongs to the category Actinopterygii. Opah fishes belong to the family Lampyridae. As per scientists, giant moon fish are warm-blooded species, the first known instance among fish. NOAA Fisheries' Southwest Fisheries Science Center is the authority on this species. The moon fish is one of the most popular species in Hawaii.
What class of animal does a moon fish belong to?
Moon fish comes under the class Actinopterygii and are also known by their scientific name Lampris guttatus. As per NOAA Fisheries' Southwest Fisheries Science Center, Lampris guttatus is said to have whole-body endothermy, where the entire core of the body sustains a temperature of around 5 °C above the surrounding water.
How many moon fish are there in the world?
There are not many studies present on the population of moon fish throughout the world, however, the IUCN has classified them as Not Extinct, so it is safe to assume their population is not threatened.
Where does a moon fish live?
As per NOAA Fisheries' Southwest Fisheries Science Center, moon fish are found in the western Atlantic Ocean. These fish are usually found in deep waters within the oceans and hence scientists have not been able to determine other important aspects of their habitat. It is assumed that this fish with large eyes is able to regulate its body temperature and can be sharing its general characteristics with other Pacific Ocean pelagic fish species.
What is a moon fish's habitat?
According to the NOAA Fisheries' Southwest Fisheries Science Center, this species resides in the open ocean or aquatic habitats at depths of around 1600 ft or below in the Atlantic Ocean, like other pelagic fish species.
Who do moon fish live with?
Moon fish are deep water predators who have evolved into fantastic hunters who can prey on various aquatic species in the dark and deep waters of the Atlantic Ocean. As the fish resides at great depths, not a lot of information is available about their companions. It is assumed that these fish are solitary creatures and do not swim in schools. But it is believed that opah fish can school with tuna and other scombrids.
How long does a moon fish live?
Moon fish mature at a relatively young age of four or five years. Their approximate life span is estimated to be 13 or 14 years. However, true longevity is unverified as this fish rarely comes to the surface and instead prefers the deep waters of the ocean.
How do they reproduce?
The moon fish reproduce through the process of spawning. As per reports, this fish species is known to spawn over vast areas especially in warm surface waters. In the tropical regions, the spawning season for moon fish lasts throughout the year. This species has impressive reproductive rates and during the breeding season, the female can spawn several times. After the larvae hatch from the eggs, they grow and transform at rapid speed. But after the transformation into the deep body's form is complete, the rate of growth slows down.
What is their conservation status?
As per reports, the conservation status of opah says that it is Not Extinct. It is assumed that the number of this opah species is steady in the oceans, hence there are no concerns regarding their survival.

How fast can a moon fish swim?
As per NOAA Fisheries' Southwest Fisheries Science Center, the pectoral fins aid the opah's speed and way of life. Those muscles cover about 17 % of the opah's body weight. They can swim at high speed and can also travel long distances.
How much does a moon fish weigh?
A moonfish weighs about 300 lb, and even larger specimens of the opah species have been reported in the open waters.

Did you know...
This sea fish is a warm-blooded or endothermic species. This implies that it can control its body temperature. This adaptation allows them to withstand the cold temperatures of the ocean water. Their capacity to retain their body heat as compared to surrounding water is a vital benefit.
During hunting in cold, deep waters, these fish can travel much faster than most animals at that depth. This enables them to find prey and surpass other predators.
What part of a car is a moon fish similar to?
Like a car radiator, it has a natural adjustment that preserves heat. The unusual location of the heat switch within the gills takes up nearly the fish's entire body to keep a raised temperature, known as endothermy, in the cold depths of ocean water.
Do moon fish migrate?
During the night, the fish migrate vertically to more temperate waters. In the daytime, opah move farther down to hunt for prey in the cool, deep waters.
