Danionella translucida
Danionella translucida is an extremely small (1.1 cm long) species of cyprinid fish endemic to Myanmar. When described, it was considered to be one of the smallest fish. It was collected from the roots of floating aquatic plants in a slow-flowing, shallow stream (maximum depth 1 m) in the Pegu Division of Myanmar. It was found alongside "Danio", "Microrasbora", "Erethistes", and "Oryzias" species. Observed in life, "D. translucida" is almost perfectly transparent except for its eyes. It has a distinctive pattern of melanophores. There are no melanophores on the dorsal surface except on the head over the  posterior part of the brain. On the posterior half of the body, there a few melanophores following the horizontal midline. The sides and underside of the abdomen have melanophores. A double row of melanophores is present on the underside of the fish from the isthmus of the gills to the pelvic fins. Eggs in "D. translucida" has been found to range in size from about in diameter, with ripe eggs being at least in diameter. Females carried anywhere from 3 to 8 or 10 eggs. Compared to the body of the fish, these eggs are relatively large.
