The first phylogenetic hypothesis of relationships among 36 extant genera of alpheid shrimps is presented, based on a cladistic analysis of 122 morphological characters from 56 species, and this hypothesis is used to explore evolutionary trends in morphology and species diversity.

With the exception of Antarctica, freshwater shrimp are present in all biogeographical regions, however, the Oriental region harbours the majority of species, whilst the Nearctic and western Palaearctic are very species-poor.

Commensal animals most frequently observed in echiuran burrows are bivalves, polychaetes, brachyuran crabs, alpheid shrimps, and copepods, which may also live in association with non-burrowing, crevice-dwelling echiurans.

Six species of the alpheid shrimp genus Salmoneus Holthuis, 1955, including two new species, are reported from the tropical western Atlantic, and Parabetaeus hummelincki is recorded for the first time in Brazil.
A MULTILOCUS TEST OF SIMULTANEOUS DIVERGENCE ACROSS THE ISTHMUS OF PANAMA USING SNAPPING SHRIMP IN THE GENUS ALPHEUS

Divergence times in two species pairs were shown to occur much earlier than the Isthmus final closure, but much of the variance in pairwise genetic distances from cytochrome oxidase I (COI) was explained when ancestral polymorphisms were accounted for.
Molecular phylogeny reveals extensive ancient and ongoing radiations in a snapping shrimp species complex (Crustacea, Alpheidae, Alpheus armillatus).

Two new species of snapping shrimps from the Indo-Pacific, with remarks on colour patterns and sibling species in Alpheidae (Crustacea : Caridea)
- A. Anker
- Biology
- 2001
Two new species of snapping shrimps belonging to the A. edwardsil group can be distinguished from all other species of Alpheus by several features of the first and second chelipeds, liontal region, third maxilliped, and most readily by their conspicuous colour patterns.
