A cataract is a clouding of the lens in your eye and normally occurs as part of the ageing process. When you develop a cataract, light is unable to pass directly through your lens to the retina, resulting in blurred vision. Cataracts are removed by surgery.
Smallest Size of Turtle Species. The prize for the smallest turtle species in the world goes to the speckled padloper tortoise (Homopus signatus). This tiny terrestrial turtle, also known as the speckled cape tortoise, travels along narrow trails and pathways in Namaqualand, South Africa. In fact, the term âpadloperâ means trail walker.
A frog species that appears to be the world's smallest has been discovered in Papua New Guinea by a US-based team. At 7mm (0.27 inches) long, Paedophryne amauensis may be the world's smallest vertebrate - the group that includes mammals, fish, birds and amphibians. The researchers also found a slightly larger relative, Paedophryne swiftorum.
