Fruiting bodies between 3–8 mm in diameter, 5–15 mm tall, and cup- or urn-shaped—having almost vertical sides with the lip flared outwards; color ranging from white, grey, buff, or tawny. Nidularia. Typically 0.5–6 mm in diameter x 0.5–3 mm tall. They may be somewhat irregular in shape, or have a well-formed cup that is thin and fragile.
During a chase, the lemmings disable Grizzy’s arms, and then his tongue when he tries to free himself with it. A panda falls on the bear and the rodents, with stones hitting the panda’s arms, resulting in making the panda strong, hugging Grizzy and the lemmings forever whilst eating the sesame nougat.
The top and bottom images produce a dent or projection depending on whether viewed with cross- () or wall- () eyed vergence. An autostereogram is a two-dimensional (2D) image that can create the optical illusion of a three-dimensional (3D) scene. Autostereograms use only one image to accomplish the effect while normal stereograms require two.
Vision is the most important sense for birds, since good eyesight is essential for safe flight. Birds have a number of adaptations which give visual acuity superior to that of other vertebrate groups; a pigeon has been described as "two eyes with wings". [ 1] Birds are theropods, [ 2][ 3] and the avian eye resembles that of other sauropsids ...

Entoptic images have a physical basis in the image cast upon the retina. Hence, they are different from optical illusions, which are caused by the visual system and characterized by a visual percept that (loosely said) appears to differ from reality. Because entoptic images are caused by phenomena within the observer's own eye, they share one ...
These two images are later used together to create a 3D image. In this way the image can be analysed giving better information about surface characteristics of the retina. [19] Fundus photography in animals: Fundus photography is a useful tool utilised for veterinary research, veterinary ophthalmology, as well as education. [20]
