Dikerogammarus Haemobaphes
''Dikerogammarus haemobaphes'' is a species of freshwater gammarid crustacean. These gammarids are commonly known as demon shrimp, likely because they are an extremely successful invasive species. Native to the Ponto Caspian basin, ''Dikerogammarus haemobaphes'' expanded their range in 1955. This expansion began in Lake Balaton, Hungary and then spread into certain rivers and lakes in Austria, Belgium, Germany, Poland, Russia, Ukraine, and the United Kingdom. These crustaceans likely broadened their range due to the interconnection of waterways in Europe and the use of transportation vectors such as boats and ships.   Identification ''Dikerogammarus haemobaphes'' have a semi-transparent, white body consisting of a head, thorax, and abdomen. Their body consists of seven segments, each with a pair of pereopods (walking legs). These shrimp are different from other gammarid species as their peduncle, flagellum of antennae, and gnathopods have short bristles rather than long o ...

Dikerogammarus Villosus
''Dikerogammarus villosus'', also known as the killer shrimp, is a species of amphipod crustacean native to the Ponto-Caspian region of eastern Europe, but which has become invasive across the western part of the continent. In the areas it has invaded, it lives in a wide range of habitats and will prey on many other animals. It is fast-growing, reaching sexual maturity in 4–8 weeks. As it has moved through Europe, it threatens other species and has already displaced both native amphipods and previous invaders. Description ''D. villosus'' can grow up to in length, relatively large for a freshwater amphipod. It varies in appearance, with some specimens being striped, and some not. It has relatively large mandibles which allow it to be an effective predator. Distribution ''D. villosus'' was originally found in the lower courses of large rivers in the Black Sea and Caspian Sea drainage basins. It has become an invasive species across central and western Europe, using the Dan ...

Gammaridae
Gammaridae is a family of amphipods. In North America they are included among the folk taxonomic category of " scuds", and otherwise gammarids is usually used as a common name. They have a wide distribution, centered on Eurasia, and are euryhaline as a lineage, inhabiting fresh to marine waters. Systematics The Gammaridae were for a long time used as a " wastebin taxon", which included numerous genera of gammaridean amphipods that since then have been removed to their own families, such as the Anisogammaridae, Melitidae, Niphargidae. The following genera are currently listed in the family: *'' Akerogammarus'' Derzhavin & Pjatakova, 1967 *'' Albanogammarus'' Ruffo, 1995 *'' Amathillina'' G. O.
