Edo wazao Edo wazao. Edo wazao (江戸和竿) is a style of handcrafted Japanese fishing rods that originated during the Edo period (1603–1868). [1] These rods are predominantly made in the Kanto region, such as Tokyo and the neighboring prefectures of Chiba and Saitama, where artisans continue the traditional methods that have been passed on for generations.
Aphyonids are small fishes, typically about 10 centimetres (3.9 in) long when fully grown.They have transparent, gelatinous skin, which lacks any scales.The dorsal, caudal and anal fins are united into a single ribbon.
An oarfish measuring 3.3 m (11 ft) and 63.5 kg (140 lb) was caught in February 2003 using a fishing rod baited with squid at Skinningrove, United Kingdom. [ 21 ] In July 2008, scientists for the first time captured footage of an oarfish swimming in its natural habitat in the mesopelagic zone in the Gulf of Mexico.
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.
The black seadevil family, Melanocetidae, was first proposed as a subfamily in 1878 by the American biologist Theodore Gill. [2] The only genus in the family is Melanocetus which was proposed as a monospecific genus in 1864 by the German-born British herpetologist and ichthyologist Albert Günther when he described the humpback anglerfish (M. johnsoni).

They range in length from about 10 cm (3.9 in) in Hymenogadus gracilis to 2.1 m (6.9 ft) in Albatrossia pectoralis. Several attempts have been made to establish a commercial fishery for the most common larger species, such as the giant grenadier , but the fish is considered unpalatable, and attempts thus far have proven unsuccessful.

Bathypelagic – the open ocean or pelagic zone that extends from a depth of 1000 to 4000 meters below the ocean surface. Beach – a geological landform along the shoreline of a body of water, consisting of loose particles composed of rock, such as sand, gravel, shingle, pebbles, or cobble, or of shell fragments or coralline algae fragments.
The defining characteristic of a vertebrate is the vertebral column, in which the notochord (a stiff rod of uniform composition) found in all chordates has been replaced by a segmented series of stiffer elements (vertebrae) separated by mobile joints (intervertebral discs, derived embryonically and evolutionarily from the notochord).
