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.
Estimated numbers left in the wild: 60,000 (very approximate). Leatherback sea turtles are the largest turtles in the world, and are fourth in size among all current reptiles. Their body is protected only by leathery, oily skin, rather than a hard shell. The leatherbackâs front flippers can grow to a spread of 2.7 meters, and the animal itself measures from 1.8 to 2.2 meters long.
