TL;DR: This compilation is the first comprehensive estimate of taxonomic diversity within the entire Decapoda, listing all known families and genera organized by higher taxonomic groups and including estimates of the number of species in every genus.
Abstract: – We present an updated classification for the entire Crustacea Decapoda, listing all known families and genera organized by higher taxonomic groups and including estimates of the number of species in every genus. All taxonomic names are also linked to the verified literature in which they were described, the first compilation of its kind for the Decapoda. To arrive at this compilation, we began with the classification scheme provided by Martin & Davis (2001) for extant families, updated the higher classification and included the fossil taxa. The resultant framework was then populated with the currently valid genera and an estimate of species numbers within each genus. Our resulting classification, spanning both extant (living) and fossil taxa, is the first comprehensive estimate of taxonomic diversity within the entire Decapoda. The classification consists of 233 families of decapods containing 2,725 genera and an estimated 17,635 species (including both extant and fossil species). Of the families in our classification, 53 are exclusively fossil, 109 contain both fossil and extant species, and 71 are extant only. The current estimate for extant species is 14,756, whereas 2,979 species are known exclusively as fossils.

TL;DR: Thalassinidean shrimp construct species-specific burrows which vary in morphology from simple 'U' or 'Y' shaped tubes to more complex tiers of galleries or reticulate branches, and each burrow type may be indicative of one of the 3 general trophic modes utilized by burrowing shrimp: deposit feeding, drift catching, and filter/suspension feeding.
Abstract: Thalassinidean shrimp construct species-specific burrows which vary in morphology from simple 'U' or 'Y' shaped tubes to more complex tiers of galleries or reticulate branches. Data on the burrow architecture of 44 species in 10 genera indicates that the morphological patterns of thalassinidean burrows are more diverse than previously recognized. Based on a review of these data and the existing information on thalassinidean feeding, we propose several generalizations in the form of a heuristic model relating burrow architecture and trophic mode in these fossorial decapods. Despite moderate levels of morphological variation between species, thalassinidean burrows can be categorized into 6 major groups based on their morphological characteristics The 6 burrow types are distinguishable based on the presence or absence of (1) surface sediment mounds at excurrent openings, (2) seagrasses in chambers or the burrow lining, and (3) a simple 'U' shaped burrow design. Although relatively little is known about the functional significance of the different architectural patterns, each burrow type may be indicative of one of the 3 general trophic modes utilized by burrowing shrimp: (1) deposit feeding, (2) drift catching, and (3) filter/suspension feeding. Two different types of burrows are discernible within the mound-producing, deposit-feeding group, 3 distinct burrow morphotypes are associated with filter/suspension feeding, and the 6th burrow morphotype is produced by the drift catchers. The ecological significance of these 6 burrow types is discussed in addition to the effects of various environmental parameters on mtraspecific variation in burrow morphology.

TL;DR: It is thought that the largely stable topology of the trees regardless of different types of analyses suggests that mitochondrial genomes show good potential to resolve the relationship within Decapoda.

TL;DR: While a large body of literature refers to many aspects of larval life histories in Thalassinideans, the focal subjects, scope, and quality vary widely, and taxonomic coverage of the group is not comprehensive.
Abstract: This chapter briefly talks about Infraorders Axiidea De Saint Laurent, 1979 and Gebiidea De Saint Laurent, 1979 (formerly known collectively as Thalassinidea). The infraorder Gebiidea de Saint Laurent, 1979a is characterized by having the first pereiopod chelate or subchelate (on rare occurrences, almost simple); and exhibiting the second pereiopod as either subchelate, or simple. The infraorder Axiidea de Saint Laurent, 1979a possesses a chelate first and second pereiopod. While a large body of literature refers to many aspects of larval life histories in Thalassinideans, the focal subjects, scope, and quality vary widely, and taxonomic coverage of the group is not comprehensive. Accounts of complete larval histories are very much biased to common and accessible members of Callianassidae and Upogebiidae, which at very least represent the two now-separated infraorders. Keywords: Callianassidae; Gebiidea De Saint Laurent, 1979; Infraorders Axiidea De Saint Laurent, 1979; larval life histories; Thalassinidea; Upogebiidae
