Histologically, the retina is composed of 10-layer elements as seen in the retina of shallow water fishes. The greatest thickness of the retina, about 200 micrometer, occurs ventrally, where rod’s outer segment is long (about 50 micrometer). Figure 4. Accessory Retina of A. affinis. The position of the accessory retina is shown in Figure 4.
Coelacanths (/ ˈ s iː l ə k æ n θ / ⓘ SEE-lə-kanth) (order Coelacanthiformes) are an ancient group of lobe-finned fish (Sarcopterygii) in the class Actinistia. [2] [3] As sarcopterygians, they are more closely related to lungfish and tetrapods (which includes amphibians, reptiles, birds and mammals) than to ray-finned fish.
The cobia is a pelagic spawner, releasing many tiny (1.2 mm), buoyant eggs into the water, where they become part of the plankton. The eggs float freely with the currents until hatching. The eggs float freely with the currents until hatching.

In migrating to the surface (400m depth) at night, they prove their ability to withstand large temperature changes of up to 7°C daily. They have been recorded in waters ranging from 4 to 14.5°C, highlighting the wide range of temperatures viperfish are capable of surviving in. [ 14 ]
Fisch began daily consultation hours from 2 to 5 pm, [4] treating a wide range of cases, from leprosy and mental illness to injuries and tropical diseases. His work was widely attended by all social classes, with some patients traveling up to 20 hours to seek his care. In his first year, Fisch reported treating over 600 African patients. [4]
[2] [26] When cooked, the taste of an oarfish is described as “like paper.” [27] R. glesne was offered to a dog who regularly consumes fish, and was refused. Six people agreed to try fried oarfish and said that the taste was suitable, but the flesh was extremely flaccid, and overall objectionable.
At sexual maturity, A. transmontanus can reach 1.6 m (5.2 ft) in length, while the maximum length recorded of any age class is 6.1 m (20 ft), with common lengths around 2.1 m (6.9 ft). While age at maturity is uncertain, possible age ranges of known A. transmontanus specimens range from 11 to 34 years old. [ 3 ]
