Photo of the day (15): Planorbarius corneus

Planorbarius corneus (Linnaeus, 1758) is a freshwater snail from the family Planorbidae. All Planorbidae have hemoglobin in its respiratory system – in its blood. It is the same respiratory protein that transport oxygen in human’s blood. Albino specimen are quite popular in aquaria, but albinos occur in nature sometimes too. When a planorbid snail is an albino snail, then the color of its hemoglobin is clearly visible and the whole snail is in bright red color.
