Lanternfish typically have a slender, compressed body covered in small, silvery deciduous cycloid scales (ctenoid in four species), a large bluntly rounded head, large elliptical to round lateral eyes (dorsolateral in Protomyctophum species), and a large terminal mouth with jaws closely set with rows of small teeth.
How long does a lantern fish live?
These species usually live in the deeper middle zone of the ocean and travel shorter distances. In warmer waters, lanternfishes spawn year-round. In cooler waters they spawn once a year. Warm-water species live one year or less, whereas cooler-water species may live three or four years.
How do lantern fish survive?
With glowing blue-green lights embedded all over its body, the aptly-named lanternfish is well equipped for seeing and signaling in the dark. Special light-producing organs called photophores line its belly, helping the fish blend in with light-speckled water and confuse predators that might attack from below.
Do lantern fish light up?
Aptly named, this flashy fish emits its own light; lantern fish have organs on their bodies, called photophores, that produce a molecule called luciferin that, when combined with oxygen, makes a blue-green light. The same way fireflies glow on land, lantern fish can glow underwater, an effect called bioluminescence.

Do lantern fish have eyes?
They also have a large, round head and large eyes. Large eyes are common in deep sea creatures as they help to collect as much light as possible in the eternally dark waters. The body of the lanternfish is covered with light-producing photophores. The arrangement of these lights varies by species.
What makes lantern fish glow?
Lanternfishes have light-producing organs on their bodies that are called photophores. This light is created by a chemical reaction, and it is one example of a phenomenon called bioluminescence.

Why do lantern fish have big eyes?
Because mesopelagic organisms live in a dim environment, their eyes need to be more sensitive than acute to be able to detect levels of downwelling light and bioluminescent flashes. To enhance sensitivity, lanternfishes possess several visual adaptations that optimize light collection and extend their visual field.
Can fish see in dark?
Fish living in the deep sea manage to navigate in complete darkness. It’s not strictly ‘seeing’ but fish have rows of pressure-sensitive organs running down each side of their body called the lateral line, which allows them to sense nearby animals from the pressure changes in the water.

What ocean zone do lantern fish live in?
Lanternfishes of the family Myctophidae live primarily in the twilight zone of the world ocean, from 200 to 1000 m in the mesopelagic zone of the water column. Lanternfishes, as their name implies, are characterised by a series of light organs or photophores on the sides of the body.
