Infraorder Anomura MacLeay, 1838

2012
This chapter briefly discusses that the Infraorder Anomura Macleay, 1838. Anomura, of all the decapod infraorders, has had a particularly unstable taxonomic history, with groups such as the dromiacean crabs and the thalassinidean shrimps being variously included and excluded over the years. The name for the group has also been vigorously debated.

XIV.—The Fæcal Pellets of the Anomura

Proceedings of the Royal Society of Edinburgh, 1933
As far back as 1678 Martin Lister, in his Historiæ Animalium Tractatus, has noted that, in the case of certain Molluscs, the fæces are of a regular form, and that their shape differs according to the species; he deduces from this that the intestine must show a corresponding difference in the various species.

An annotated and illustrated checklist of the porcelain crabs of Panama (Decapoda: Anomura)

Zootaxa, 2021
The present study is the first exhaustive checklist of porcelain crabs (Porcellanidae) distributed on the Pacific and Atlantic (Caribbean) coasts of Panama, based on literature records and material collected between 2006 and 2019. The Panamanian porcellanid fauna is currently composed of a total of 76 species, with 26 species reported from the ...

The Chirostylidae of southern Australia (Crustacea: Decapoda: Anomura)

Zootaxa, 2004
The deep-water squat lobsters, Chirostylidae, of southern Australia are reported, comprising 31 species in three genera, increasing the known Australian fauna from 8 to 34. Two species of Eumunida Smith are reported, one of which, E. capillata de Saint Laurent & Macpherson, is a new record for Australia.

LARVAL AND ADULT STAGES OF BRITISH COLUMBIA ANOMURA

Canadian Journal of Research, 1937
The external morphology of the adult stage of four species of Anomura (hermit crabs), Upogebia pugettensis (Dana), Paguristes turgidus (Stimpson), Pagurus beringanus (Benedict) and Orthopagurus schmitti (Stevens) is compared and the larval stages described.

Digging in Sand Crabs (Decapoda, Anomura, Hippoidea): Interleg Coordination

Journal of Experimental Biology, 1997
ABSTRACT Sand crabs (Decapoda, Anomura, Hippoidea) are highly specialised for digging into sand using their thoracic legs. Using video-recording and electromyography, we examined the digging leg movements of three species of sand crabs belonging to two families: Blepharipoda occidentalis (Albuneidae), Lepidopa californica (Albuneidae ...

Reduction of Maxillary Endites in Larval Anomura and Brachyura

Crustaceana, 1982
The typical zoeal maxilla is a structurally complex and highly modified appendage. Although reduced in morphology from the generalized crustacean limb so that it appears to be a single segment, certain features remain distinguishable. Coxal and basal endites, usually bilobed and armed with setae, arise from the protopodite (the fused coxa and basis). A

Breeding biology of the intertidal sand crab, Emerita (Decapoda: Anomura)

2003
Emerita is a burrowing mole crab or sand crab, adapted to life in wave-washed sandy beaches of temperate and tropical seas. The reproductive biology of this anomuran crab presents several peculiarities, all contributing to its adaptation to this harsh environmental niche.

Repetitive DNA sequences as an insight into Aeglidae (Crustacea, Anomura) evolution

ELECTROPHORESIS, 1997
AbstractThe evolutionary relationships of five Atlantic Aeglidae species (Aegla neuquensis affinis, A. humahuaca, A. jujuyana, A. platensis, and A. uruguayana) were studied by (i) satellite DNA analysis using a restriction enzyme digestion and hybridization pattern approach and (ii) genome screening by using randomly amplified polymorphic DNA (RAPD ...

Spermatozoal ultrastructure in the Hippoidea (Anomura, Decapoda)

1999
Three species of anomuran mole and sand crabs (Albunea sp., Emerita talpoida and Hippo pacifica) in the superfamily Hippoidea are investigated for spermatozoal ultrastructure. Each species has a different spermatozoal morphology but shares, with the others, three apomorphies - a thickened, multi-layered operculum, a perforatorial septum, and a central ...
