Megaloblastic Anemia (MGA), also known as Pernicious Anemia, is a rare blood disorder characterized by the presence of large, structurally and visually abnormal, immature red blood cells (megaloblasts). Decreased numbers and immaturity of white blood cells (leukocytes) and blood platelets (thrombocytes) may also occur.
6. Reflective Tissue: Deer have a layer of tissue in their eyes that reflect light back towards the photo-receptors. This tissue layer is called tapetum lucidum and helps deer see better during low light conditions (e.g, dusk and dawn) and makes their eyes appear to glow when reflecting light (e.g., headlights).Many other animals have this tissue layer as well.his tissue layer is called tapetum lucidum and helps deer see better during low light conditions (e.g, dusk and dawn) and makes their eyes appear to glow when reflecting light (e.g., headlights).

Exactly how well deer see UV light is debatable. Clothing can contain UV brighteners, additives incorporated in some fabrics and detergents that supposedly make the clothes appear brighter. According to one theory, such clothing makes hunters glow in the dark to a deer's eyes.ust as human ears can't hear some sounds, human eyes can't see some light. These invisible wavelengths include ultraviolet (beyond violet) and infrared (below red). Deer sense colors toward the violet end of the spectrum, so they can see blues and probably even ultraviolet (UV) light.
