The Ganges river dolphin (Platanista gangetica gangetica) is an endangered, virtually blind freshwater cetacean native to the Ganges, Brahmaputra, and Meghna river systems in India, Bangladesh, and Nepal. Adapted to navigating murky, sediment-heavy waters, this subspecies lacks a functional crystall...
The Blanco Blind Salamander (Eurycea robusta) is a rare, depigmented aquatic salamander from the Edwards Plateau of Hays County, Texas, known from very few specimens collected from underground waters.
Eurycea troglodytes is a cave-adapted lungless salamander in the family Plethodontidae, endemic to the Valdina Farms Sinkhole system in Medina County, Texas. It is one of several Eurycea salamanders associated with the subterranean aquatic habitats of the Edwards Plateau karst region in central Texa...
Cryptolithus is an extinct genus of trinucleid trilobite that lived during the Ordovician period. It is distinguished by its broad, perforated cephalic fringe, which extends outward from the head and is commonly referred to as a "lace collar." The genus was entirely blind, lacking compound eyes. Fos...
Blind cricket is an adaptation of cricket for blind and partially sighted players. It uses an audible ball containing bearings or similar noise-producing material, verbal calls between players, and modified delivery and fielding rules so participants can locate the ball through sound. Teams are clas...
Beep baseball is an adaptive form of baseball designed primarily for blind and visually impaired athletes. Players track an audible ball, run toward one of two buzzing bases after a hit, and attempt to score before a sighted defensive player fields the ball; pitchers and catchers are typically sight...
The Planina cave shrimp is an endemic, pigment-free freshwater crustacean native to subterranean waters in Slovenia. Classified within the family Atyidae, it exhibits typical cave-adapted traits including elongated appendages and sensory structures suited to life in total darkness. The species is pa...
Blind baseball is an adapted form of baseball designed to enable blind and visually impaired athletes to participate in batting, running, fielding, and team competition. The sport uses an audible ball so fielders can locate it by sound, while sighted assistants perform limited safety and organizatio...
Trinucleus is an extinct genus of trilobites that thrived during the Ordovician period, with fossils primarily located in Wales, Britain, and other parts of Europe. Belonging to the order Trinucleida, this genus lacked eyes and relied on other sensory mechanisms. It is highly distinguished by a broa...
Ordovician to Silurian trilobite of the family Raphiophoridae with a streamlined body form, known from shallow to mid-shelf marine deposits of Laurentia and Baltica.
Ampyx is an extinct genus of trilobite from the order Trinucleida that lived during the Ordovician period. These blind trilobites are easily recognized by the long, prominent glabellar spine that extends forward from the front of their cephalon, as well as their distinct genal spines. Fossil specime...
Middle Cambrian trilobite notable for the complete absence of eyes, abundant in Bohemian and Iberian Cambrian deposits and a classic example of trilobite blindness.
An Ordovician trilobite known for its elongated frontal or rostral spine, found in Baltic and North American Ordovician strata and classified within the order Asaphida.
Ordovician raphiophorid trilobite distinguished by a prominent forward-projecting rostral spine, found across European and North African shallow-marine Ordovician deposits.
Ordovician trinucleid trilobite distributed across Europe and North Africa, notable for a broad cephalic fringe densely perforated by regularly arranged pits whose function remains debated.
A genus of small blind Cambrian agnostid trilobites with cosmopolitan distribution, serving as useful biostratigraphic index fossils across multiple paleocontinents.
Ordovician trinucleid trilobite from European strata, characterized by a wide pitted cephalic fringe and an eyeless cephalon, consistent with the trinucleoid infaunal lifestyle.
Ordovician trinucleid trilobite with a broad cephalic fringe bearing concentric rows of pits, widely distributed across European and North African Late Ordovician shelf deposits.
Small Ordovician raphiophorid trilobite found in European strata, notable for its simplified exoskeleton and reduced pygidium relative to the proportionally large cephalon.
A Late Cambrian agnostid trilobite genus whose type species, Agnostotes orientalis, defines a key global biozone near the Cambrian–Ordovician boundary.
Eodiscus is a Cambrian trilobite that serves as the type genus of the order Eodiscida, known from Burgess Shale-type deposits in North America.
Acadagnostus is a Cambrian agnostid trilobite described by Kobayashi in 1939, known from North America, Europe, and Australia.
A tiny blind Cambrian agnostid trilobite with nearly identical head and tail shields, distributed globally and widely used as a biostratigraphic index fossil.
A Cambrian agnostid trilobite with worldwide distribution, serving as an important biostratigraphic index fossil for Middle to Late Cambrian correlations.
