Sinopoda scurion is a species of huntsman spider discovered in 2012 in a Laotian cave. It has a leg span of about 6 centimetres (2.4 in) and a body span of about 12 millimetres (0.47 in). It is the first recorded huntsman spider to lack eyes. [1] Due to its dark cave habitat, it has no requirement of vision for hunting. [2]
The species is classified as a member of troglofauna, more precisely a troglobiont species, meaning such spiders are obligate cave-dwellers adapted to living in dark surroundings. [3] [4] Stalita taenaria is a species of a few European countries. [5] The spider is thought to be the first described species of true (eyeless [6]) cave spider in ...

Ciba is a genus of Caribbean wandering spiders first described in 2014. [2] As of April 2019 it contains only two species. [1] It is one of two species of eyeless spiders found in a Hispaniola cave. The non-expression of eyes and eye pigment in Ciba spiders is an energy-saving adaption in response to their dark cave habitat. [2]

In one experiment studying eye development, University of Maryland scientists transplanted lenses from the eyes of sighted surface-form embryos into blind cave-form embryos, and vice versa. In the cave form, lens development begins within the first 24 hours of embryonic development, but quickly aborts, the lens cells dying; most of the rest of ...
Leptonetidae is a family of small spiders adapted to live in dark and moist places such as caves. [1] The family is relatively primitive having diverged around the Middle Jurassic period. [ 2 ] They were first described by Eugène Simon in 1890.
