Troglocaris anophthalmus is a species of freshwater shrimp in the family Atyidae. It lives in karstic caves in Bosnia and Herzegovina, Croatia, Italy and Slovenia. [1] Although morphologically similar across its 500-kilometre (310 mi) range, molecular phylogenetics suggests that there are four or five cryptic lineages with more restricted ranges, although one such lineage does range unusually widely for a troglobite – over 300 kilometres (190 mi). [3]


Like other underground-living animals, this shrimp lacks pigment (appearing whitish) and eyes. The carapace length is typically about 0.5–0.9 cm (0.20–0.35 in). [4]

It was originally described by Vincenz Kollar as Palaemon anophtalmus (a misspelling of "anophthalmus"), but this name was considered to be a nomen nudum for a long time. This name is, however, accompanied by a description, and predates Dormitzer's junior synonym Troglocaris schmidtii. [2]

Caridea Infraorder of shrimp

The Caridea, commonly known as caridean shrimp or true shrimp, are an infraorder of shrimp within the order Decapoda. They are found widely around the world in both fresh and salt water.

Malacostraca Largest class of crustaceans

Malacostraca is the largest of the six classes of crustaceans, containing about 40,000 living species, divided among 16 orders. Its members, the malacostracans, display a great diversity of body forms and include crabs, lobsters, crayfish, shrimp, krill, woodlice, amphipods, mantis shrimp and many other, less familiar animals. They are abundant in all marine environments and have colonised freshwater and terrestrial habitats. They are segmented animals, united by a common body plan comprising 20 body segments, and divided into a head, thorax, and abdomen.

Eucarida Superorder of crustaceans

Eucarida is a superorder of the Malacostraca, a class of the crustacean subphylum, comprising the decapods, krill, Amphionides and Angustidontida. They are characterised by having the carapace fused to all thoracic segments, and by the possession of stalked eyes.

Atyidae Family of crustaceans

Atyidae is a family of shrimp, present in all tropical and most temperate waters of the world. Adults of this family are almost always confined to fresh water. This is the only family in the superfamily Atyoidea.

Axiidea Infraorder of crustaceans

Axiidea is an infraorder of decapod crustaceans. They are colloquially known as mud shrimp, ghost shrimp, or burrowing shrimp; however, these decapods are only distantly related to true shrimp. Axiidea and Gebiidea are divergent infraoders of the former infraorder Thalassinidea. These infraorders have converged ecologically and morphologically as burrowing forms. It is now widely believed that these two infraorders represent two distinct lineages separate from one another; however, this separation occurred in 2009 based on molecular evidence. As a result, much of the literature and research surrounding these infraorders still refers to the Axiidea and Gebiidea in combination as "thalassinidean" for the sake of clarity and reference. This division based on molecular evidence is consistent with the groupings proposed by Robert Gurney in 1938 based on larval developmental stages.

Paratya curvirostris is a species of freshwater shrimp in the family Atyidae. It is endemic to New Zealand, where it is distributed from North Island to Stewart Island, and including the Chatham Islands. It is the only true decapod shrimp to inhabit freshwater in New Zealand.

<i>Troglocaris</i> Genus of crustaceans

Troglocaris is a genus of freshwater shrimp in the family Atyidae. These stygobitic, whitish and eyeless shrimp are found in Southern Europe. Although locally very common, the small ranges of the individual species make them highly vulnerable to habitat loss, for example by water extraction. Their underground habitat is often extremely stable; for example, the Vipavska jama cave in Slovenia is home to a population of T. anophthalmus, and its water only varies from 10 °C (50 °F) in the winter to 11 °C (52 °F) in the summer. In some Dinaric caves, notably Vjetrenica, as many as three species may occur together.

Typhlatya is a genus of shrimp in the family Atyidae. These are small, stygobitic shrimp found in the West Mediterranean region, Caribbean region, Ascension Island and the Galápagos, although the individual species often have very small ranges. Species in this genus are found in salt, brackish and fresh waters, mostly in anchialine habitats and none in the open sea.

<i>Neocaridina davidi</i> Species of crustacean

Neocaridina davidi is a freshwater shrimp from Taiwan which is commonly kept in aquaria. The natural coloration of the shrimp is green-brown. There are a wide range of colors such as red, yellow, orange, green, blue, violet, black, etc., however, the red morph is more frequently sold. The density of coloration on adult shrimp, dependent on breeding, determines their sale price and "quality" (grading). This "quality" is purely aesthetic, as the size, behavior and other characteristics of the animal is more or less equal across varieties. Full-grown shrimp reach about 4 centimetres (1.6 in) long. They prefer clean water, with a pH of 6.5-8, and a temperature of 14–29 °C (57–84 °F) They are most comfortable at 22 °C (72 °F). N. davidi shrimp are omnivores that may live 1–2 years. These shrimp have previously been classified as Neocaridina heteropoda and Neocaridina denticulata sinensis, however are now known as Neocaridina davidi which is based on the oldest known published description of the species.

<i>Potamon fluviatile</i> Species of crab

Potamon fluviatile is a freshwater crab found in or near wooded streams, rivers and lakes in Southern Europe. It is an omnivore with broad ecological tolerances, and adults typically reach 50 mm (2 in) in size during their 10–12 year lifespan. They inhabit burrows and are aggressive, apparently outcompeting native crayfish.

Phylogeny of Malacostraca is the evolutionary relationships of the largest of the six classes of crustaceans, containing about 40,000 living species, divided among 16 orders. Its members display a great diversity of body forms. Although the class Malacostraca is united by a number of well-defined and documented features, which were recognised a century ago by William Thomas Calman in 1904, the phylogenetic relationship of the orders which compose this class is unclear due to the vast diversity present in their morphology. Molecular studies have attempted to infer the phylogeny of this clade, resulting in phylogenies which have a limited amount of morphological support. To resolve a well-supported eumalacostracan phylogeny and obtain a robust tree, it will be necessary to look beyond the most commonly utilized sources of data.

<i>Caridina dennerli</i> Species of crustacean

Caridina dennerli is a small species of freshwater shrimp from Sulawesi (Indonesia) that grows up to 2.5 centimetres (1.0 in) in length. It takes its name from the German company Dennerle, which supported the expedition that led to the scientific description of the species. It is popularly known as the 'Cardinal Shrimp' in the aquarium trade.

Caridina spongicola is a small species of freshwater shrimp from Sulawesi (Indonesia) that reaches 0.64 to 1.27 cm in length. In the wild it strictly lives on an undescribed species of freshwater sponge, making it one of only two known commensal species of freshwater shrimp. It is popularly known as the harlequin shrimp, and also sometimes Celebes beauty shrimp or sponge shrimp in the aquarium trade. It is often confused with Caridina woltereckae, a larger and more contrastingly colored species found in the same region as C. spongicola.
