KING crabs (Family Lithodidae) are among the world's largest arthropods, having a crab-like morphology and a strongly calcified exoskeleton1–6. The hermit crabs, by contrast, have depended on gastropod shells for protection for over 150 million years5,7. Shell-living has constrained the morphological evolution of hermit crabs by requiring a decalcified asymmetrical abdomen capable of coiling into gastropod shells and by preventing crabs from growing past the size of the largest available… Expand
The origin of king crabs: hermit crab ancestry under the magnifying glass
TLDR
It is suggested that the advances resulting from abandoning a shell-inhabiting lifestyle, rather than constraints of such shelters, played a central role in carcinization in this taxon. Expand
Hermit to king, or hermit to all: multiple transitions to crab-like forms from hermit crab ancestors.
TLDR
It is shown by phylogenetic analysis of five nuclear protein-coding gene sequences that hermit crabs have a single origin, but surprisingly, that almost all other major clades and body forms within the Anomura, are derived from within the hermit crab. Expand
The anatomy of the king crab Hapalogaster mertensii Brandt, 1850 (Anomura: Paguroidea: Hapalogastridae): new insights into the evolutionary transformation of hermit crabs into king crabs
TLDR
This work studied the hemolymph vascular system and associated organs of representatives of Hapalogaster and presents the first micro-computer tomography data pertaining to the internal anatomy of hapalogastrids, an evolutionary intermediate form that connects pagurids and lithodids. Expand
Evolution of crabs – history and deconstruction of a prime example of convergence
TLDR
A definition of what a crab is is proposed and it is shown that not all Brachyura are crabs in the typological sense, which reveals that carcinization does not involve such dramatic changes in morphology as has been suggested. Expand
Evolutionary morphology of the hemolymph vascular system in hermit and king crabs (Crustacea: Decapoda: Anomala)
TLDR
Internal organs such as the hemolymph vascular system and adjacent anatomical structures of several Recent hermit crab and king crab species led to an increase in the potential for intraspecific variability and interspecific variation in the arterial branching pattern. Expand

crabs at all, being members ofthe Anomura. Well known examples are the anomuran king crabs (family Lithodidae) for which it has been argued recently that they form the sister group of a particularExpand
Aspects of evolution in the anomuran superfamily Paguroidea: one larval prospective
TLDR
The megalopal and first or first- and second-crab stages of representatives of both subfamilies of the Lithodidae provide the first of such larval information that disprove the Bouvierian concept of lithodid abdominal plate development and lend substantial support to McLaughlin and Lemaitre's hypothesis. Expand
Rapid evolution to terrestrial life in Jamaican crabs
TLDR
Molecular evidence is presented that Jamaican land crabs represent a single adaptive radiation from a marine ancestor that invaded terrestrial habitats only 4 million years ago and probably reflects the Mid-Tertiary inundation of that island. Expand
Chromosome‐level genome assembly of Paralithodes platypus provides insights into evolution and adaptation of king crabs
TLDR
Gen families related to developmental pathways, steroid and thyroid hormone synthesis, and inflammatory regulation were expanded in the genome, suggesting that these genes contributed substantially to the environmental adaptation and unique body plan evolution of the blue king crab. Expand
Exceptional preservation of mid-Cretaceous marine arthropods and the evolution of novel forms via heterochrony
TLDR
A new, exceptionally preserved enigmatic crab from the mid-Cretaceous of Colombia and the United States is described, whose completeness illuminates the early disparity of the group and the origins of novel forms. Expand

Size, shell–living and carcinization in geographic populations of a hermit crab, Pagurus hirsutiusculus
TLDR
Measurements derived from image analysis of P. hirsutiusculus specimens from geographic locations along the Pacific coast of North America show that Alaskan specimens: (1) are larger, (2) exhibit reduced snail shell–living, and (3) have relatively broader anterior carapaces than southern Californian specimens.

VARIATION OF CHELIPED ALLOMETRY IN A HERMIT CRAB: ThE ROLE OF INTRODUCED PERIWINKLE SHELLS
TLDR
Geographic patterns of shell use may indicate that periwinkle shells increased the shells available to P. longicarpus in New England, and may be responsible for the correlation between use of L. littorea shells and reduced right cheliped allometry in field populations. Expand
MOLECULAR AND GEOLOGIC EVIDENCE OF SHARED HISTORY BETWEEN HERMIT CRABS AND THE SYMBIOTIC GENUS HYDRACTINIA
TLDR
A linear scaling between a measure of hydroid sequence divergence and independent geologic estimates of the timing of the vicariant events believed to have established the hermit crab range disjunctions is consistent with the claim of temporal coincidence of cladogenic and vicariance events. Expand
Hermit Crabs―are They Really Polyphyletic?
TLDR
The question of hermit crab phylogeny (including the lithodids) is re-examined using cladistic methodology and the families Pomatochelidae, Diogenidae, Coenobitidae, Paguridae, Parapagur Families, and Lithodidae are reunited under the superfamily Paguroidea, infraorder Anomala. Expand
The Main Features of Brachyuran Evolution
TLDR
It seems obvious that the Brachyura have reached the highest organizational level found among the decapod Crustacea, and this new level of organization has led to great biological improvement as manifested by taxonomic diversity, wide distribution and the ability to leave the primary (littoral) environment.

Phylogenetic Relationships of the Genus Aegla (Decapoda: Anomura: Aeglidae), With Comments on Anomuran Phylogeny
TLDR
A proposed hypothesis of anomuran phylogeny separates thalassinoids from Anomura sensu stricto, places aeglids with other galatheoids, and removes lithodids and Lomis from the paguroid line. Expand

When Biotas Meet: Understanding Biotic Interchange
TLDR
Studies of episodes of marine and terrestrial biotic interchange that have occurred during the last 20 million years show that large-scale extinction of species before the onset of interchange renders biotas especially prone to invasion. Expand
Size and shape in ontogeny and phylogeny
TLDR
A quantitative method for describing how heterochronic changes in ontogeny relate to phyletic trends is presented, and a greatly simplified and logical scheme of classification is obtained that will be particularly useful in studying the data of paleontology and comparative morphology. Expand
Accuracy of estimating genetic distance between species from short sequences of mitochondrial DNA.
TLDR
The influence of the number of basepairs on genetic distance estimates based on mtDNA sequence data is investigated by randomly subsampling known DNA sequences and then determining the variance of geneticdistance estimates among subsamples. Expand
