Hogna wolf spider (family Lycosidae) showing the enlarged posterior median eyes typical of the family. The eyes of spiders vary significantly in their structure, arrangement, and function. They usually have eight, each being a simple eye with a single lens rather than multiple units as in the compound eyes of insects. The specific arrangement ...
Canthigaster amboinensis, commonly known as the Ambon pufferfish, the Ambon toby, or the spider-eye puffer, is a species of pufferfish of the family Tetraodontidae. The species is commonly seen in the tropical Indo-Pacific Ocean, including Australia, Indonesia, Japan, Papua New Guinea, Taiwan and the Hawaiian Islands . [ 2 ]
Six-eyed spiders are spiders that, unlike most spider species, lack the principal pair of eyes, leaving them with only six eyes instead of the usual eight. [ 1 ] List

Originally, Megarachne (meaning "great spider" in Ancient Greek) was classified as a member of the Mesothelae, until further examination has proven to it being a species of eurypterid, an extinct arthropod. A number of families and genera of fossil arthropods have been assigned to the Mesothelae, particularly by Alexander Petrunkevitch.
Caponiidae are unusual in the degree to which the eye number varies. In this they surpass even the family Cybaeidae in which some species have two eyes, some six, and some eight. In some species of the Caponiidae paired eyes meet in the midline, giving the spider in effect, an odd number of eyes. The following genera have eyes as follows:

Oonopidae are frequently encountered as subfossils preserved in copals and as fossils preserved in amber.Oonopids even occur in more amber deposits than any other spider family, which may be accounted for by their widespread distribution, small size, and wandering behaviour, as amber appears to be biased towards trapping such spiders.
