Ridgehead

Scopelogadus mizolepis

The large scale fish ( Melamphaidae ) living with about 50 species in five genera in all oceans except the Arctic Sea and the Mediterranean. They are the most species-rich order of the mucus -like head ( Beryciformes ).

Appearance

Latticed fish have an elongated, laterally slightly compressed body. Your scaleless head is provided with sharp, skin -covered thorns and spikes. The bones of the head are paper- thin and keeled. Similar to the mucus -like head ( Beryciformes ) have the large scale fish slime- filled gullies on the skull, which probably improve the sensory abilities of animals. In contrast, the lateral line is regressed no longer present or to one or two pore- bearing scales. The eponymous large cycloid scales are usually dark brown or black. They fall off easily. With the exception of Poromitra megalops the eyes are very small. The Maul column extends to behind the eye. Latticed fish have a single dorsal fin and a forked tail fin. The tail fin ahead stand up and down on the tail fins handle three to four spines. The dorsal fin is supported by three weak spines and subsequent soft rays, the pelvic fins have a sting ray and six to eight soft rays. Latticed fish are 2-18 inches long. The spine consists of 24 to 31 vertebrae.

Habitat

Latticed fish live in depths of 0-4000 meters. Many hiking during the day, during the day they stay on at depths below 400 meters and rise to the surface at night (10-100 meters). As they find more booty here Latticed fish preferred to keep on the continental slopes and seamounts sub.

Reproduction

Latticed pelagic fish spawn in the open water. Eggs and larvae are zooplankton and drive in water layers above 200 meters. Following metamorphosis, the adult fish drag the animals into deeper layers in the living room of the parents.

Others

Latticed fish are eaten by dolphins, albatrosses, tuna fish and squids. You yourself eat zooplankton, such as copepods and other small pelagic crustaceans.
