What is a fish with light on head called?
The barreleye (Macropinna microstoma) has extremely light-sensitive eyes that can rotate within a transparent, fluid-filled shield on its head. The fish's tubular eyes, well inside the head, are capped by bright green lenses. The eyes point upward (as shown here) when the fish is looking for food overhead.
Is there a fish with a light on its head?
The angler fish is an interesting deep sea creature that is known for its strange light on its head. This light attaches to the top of the fishes head and extends right in front of his mouth.

What do fish have a light on its head?

What is the name of fish with the light bulb on its head?
The Pacific footballfish is a type of anglerfish, with a modified dorsal fin called the illicium, an arm-like filament that extends outward from its head and has a bulb on the end. Anglerfish, which live in dark ocean waters up to 3,000 feet down, are able to "light" this bulb to attract prey.
What is the fish called with a light on it?
flashlight fish, also called lantern-eye fish, any of three species of fishes in the family Anomalopidae (order Beryciformes), characterized by the presence of luminescent organs just below the eye. They are among the few species of non-deep-sea fishes to possess such organs.

Why do anglerfish have a light on their head?

Are anglerfish blind?
As revealed from the Anglerfish Fossil within Ember Twin, Anglerfish are blind and hunt using sound. The player can freely pass as close as they wish and as fast as they wish, as long as they are not making any sound when doing so. Rotational thrusters will not alert them but directional thrusters will.

Do any aquariums have anglerfish?
A rare fish which lives up to 1,000 metres below the surface has taken residence at an aquarium in Blackpool. Sealife Blackpool claim it is the first aquarium in the UK to exhibit the deep sea anglerfish.

Why is the light gland open to the exterior of the fish?
The light gland is always open to the exterior, so it is possible that the fish acquires the bacteria from the seawater.
Where do anglerfish get their luminescence?
The luminescence comes from symbiotic bacteria, which are thought to be acquired from seawater, that dwell in and around the esca. Some anglerfish are notable for extreme sexual dimorphism and sexual symbiosis of the small male with the much larger female, seen in the suborder Ceratiidae, the deep sea anglerfish.
What is the esca on a frogfish?
Most adult female ceratioid anglerfish have a luminescent organ called the esca at the tip of a modified dorsal ray (the illicium or fishing rod; derived from Latin ēsca, "bait").
Why are anglerfish called anglerfish?
The name "anglerfish" derives from the species' characteristic method of predation. Anglerfish typically have at least one long filament sprouting from the middle of their heads, termed the illicium. The illicium is the detached and modified first three spines of the anterior dorsal fin.
How big is the anglerfish egg?
The spawn of the anglerfish of the genus Lophius consists of a thin sheet of transparent gelatinous material 25 cm (10 in) wide and greater than 10 m (33 ft) long. Such an egg sheet is rare among fish. The eggs in this sheet are in a single layer, each in its own cavity. The spawn is free in the sea.
Why do anglerfish need to quickly find a female?
These features mean the male must quickly find a female anglerfish to prevent death. The sensitive olfactory organs help the male to detect the pheromones that signal the proximity of a female anglerfish. The methods anglerfish use to locate mates vary.
Why do anglerfish fusion?
In some species of anglerfish, fusion between male and female when reproducing is possible due to the lack of immune system keys that allow antibodies to mature and create receptors for T-cells. Certain ceratioids rely on parabiotic reproduction.
Overview
The anglerfish are fish of the teleost order Lophiiformes . They are bony fish named for their characteristic mode of predation, in which a modified luminescent fin ray (the esca or illicium) acts as a lure for other fish. The luminescence comes from symbiotic bacteria, which are thought to be acquired from seawater, that dwell in and around the sea.

Evolution
A mitochondrial genome phylogenetic study suggested the anglerfishes diversified in a short period of the early to mid-Cretaceous, between 130 and 100 million years ago.
Classification
FishBase, Nelson, and Pietsch list 18 families, but ITIS lists only 16. The following taxa have been arranged to show their evolutionary relationships.
• Suborder Lophoiodei
• Suborder Antennarioidei
• Suborder Chaunacoidei
Anatomy
All anglerfish are carnivorous and are thus adapted for the capture of prey. Ranging in color from dark gray to dark brown, deep-sea species have large heads that bear enormous, crescent-shaped mouths full of long, fang-like teeth angled inward for efficient prey grabbing. Their length can vary from 2–18 cm (1–7 in), with a few types getting as large as 100 cm (39 in), but this variation is largely due to sexual dimorphism, with females being much larger than males. Frogfish and othe…
Behavior
In 2005, near Monterey, California, at 1,474 metres depth, an ROV filmed a female ceratioid anglerfish of the genus Oneirodes for 24 minutes. When approached, the fish retreated rapidly, but in 74% of the video footage, it drifted passively, oriented at any angle. When advancing, it swam intermittently at a speed of 0.24 body lengths per second, beating its pectoral fins in-phase. The lethargic behavior of this ambush predator is suited to the energy-poor environment of the deep s…
Threats
Northwest European Lophius species are listed by the ICES as "outside safe biological limits". Additionally, anglerfish are known to occasionally rise to the surface during El Niño, leaving large groups of dead anglerfish floating on the surface.
In 2010, Greenpeace International added the American angler (Lophius americanus), the angler (Lophius piscatorius), and the black-bellied angler (Lophius budegassa) to its seafood red list—a …
Human consumption
One family, the Lophiidae, is of commercial interest with fisheries found in western Europe, eastern North America, Africa, and East Asia. In Europe and North America, the tail meat of fish of the genus Lophius, known as monkfish or goosefish (North America), is widely used in cooking, and is often compared to lobster tail in taste and texture.
In Asia, especially Korea and Japan, monkfish liver, known as ankimo, is considered a delicacy. …
