The eye is 27 cm (10 + 1 ⁄ 2 in) wide, with a lens 12 cm (4 + 1 ⁄ 2 in) across. This is the largest eye of any known animal. [30] These measurements are of the partly collapsed specimen; alive, the eye was probably 30 [31] to 40 cm (12 to 16 in) across. [57] Inspection of the specimen with an endoscope revealed ovaries containing thousands ...
Consequently, many molluscs may have a multitude of eyes in more unlikely places, such as along the edge of their shell. [1] Chitons have a dispersed network of tiny eyes over the surface of their shells which may act together as a compound eye. [1] Many gastropods have stalked eyes; the eye can be retracted into the stalk itself in the ...
Ophthalmosaurus (Greek ὀφθάλμος ophthalmos 'eye' and σαῦρος sauros 'lizard') is a genus of ichthyosaur known from the Middle-Late Jurassic. Possible remains from the earliest Cretaceous, around 145 million years ago, are also known. It was a relatively medium-sized ichthyosaur, measuring 4 m (13 ft) long and weighing 940 kg ...
This is three times the size of the largest fish eyes—up to 90 mm (3.5 in) in swordfish—and more than twice the diameter of the largest whale eyes—up to 109 mm (4.3 in), 61 mm (2.4 in), and 55 mm (2.2 in) in blue, humpback, and sperm whales, respectively—which are the largest among vertebrates. [5]
From 1926 until 1972, London Zoo, followed by several other zoos around the world, held a chimpanzees' tea party daily, inspiring a long-running series of advertisements for PG Tips tea featuring such a party. [156] [157] Animal rights groups have urged a stop to such acts, considering them abusive. [158] Poster for the 1931 film Aping ...
The ostrich has the largest eye of any land vertebrate, with an axial length of 50 mm (2.0 in), twice that of the human eye. [1] Bird eye size is broadly related to body mass. A study of five orders (parrots, pigeons, petrels, raptors and owls) showed that eye mass is proportional to body mass, but as expected from their habits and visual ...

Most batoids have a flat, disk-like body, with the exception of the guitarfishes and sawfishes, while most sharks have a spindle-shaped body. Many species of batoid have developed their pectoral fins into broad flat wing-like appendages. The anal fin is absent. The eyes and spiracles are located on top of the head.
