> Abstract In the debate over phylogenetic relationships within the Decapoda that has raged for more than a century, the Anomura has been the source of many "conflicts", including disagreements over which taxa belong in this morphologically diverse infraorder, and even what name is appropriate (Anomura or Anomala). The Anomura currently includes 17 families, 222 genera, and about 2,469 species,...

The decapod crustaceans of the Gulf of Oman have been documented based on the published literature and new sampling along the Iranian coast between 2005 and 2015. A total of 121 species were collected along the Iranian coast, of which 43 are new records for the Gulf of Oman. The Decapoda of the Gulf is currently represented by 258 species belonging to five infraorders: Axiidea, Achelata, Anomur...

Samples and images of deep-water benthic decapod crustaceans were collected from the Nikko Seamounts, Mariana Arc, at depths of 520-680 m, by using the remotely operate vehicle "Hyper-Dolphin", equipped with a high definition camera, digital camera, manipulators and slurp gun (suction sampler). The following seven species were collected, of which three are new to science: Plesionika unicolor n....

Eight species of Brachyura and two species of Anomura were registered for the first time on the Santa Catarina coast, in the waters around the Arvoredo Marine Biological Reserve. The animals were collected by scuba divers, between 3 and 22 meters depth, from September 2001 to February 2003. A total of 31 decapod species were collected, and most of the new occurrences had already been registered...

Contesting animals typically gather information about the resource value and that information affects fight motivation. However, it is possible that particular resource characteristics alter the ability to fight independently of the motivation. Using hermit crabs, we investigate how the resource in terms of shell quality affects both motivation and ability to fight. These crabs fight for shells...

Evidence is provided to support the synonymy of two species sand crabs (Anomura: Albuneidae). Zygopa lalanai Ortiz, 2015 a synonym michaelis Holthuis, 1961 and Lepidopa boykoi Tello-Musi Morales-Moreno, 2018 benedicti Schmitt, 1935. Each recently described was based on single specimen collected well within range their respective senior synonyms.

Animals titrate their behaviour against the level of risk and an individual's conspicuousness should influence decisions such as when to flee and for how long to hide. Conspicuousness will vary with variation in substrate colour. Since hermit crabs frequently change the shells they occupy, shell colour will also influence conspicuousness and to be aware of their conspicuousness would require in...
