Host-related Morphological Variation of Dwellings Inhabited by the Crab Domecia acanthophora in the Corals Acropora palmata and Millepora complanata (Southern Caribbean)

Diversity, 2020
Brachyuran crabs of various families are known as obligate associates of stony corals, with many of these species living as endosymbionts inside the skeleton of their hosts [...]

Is Eocarcinus Withers, 1932, a Basal Brachyuran? [PDF]

Journal of Crustacean Biology, 2010
Abstract Eocarcinus praecursor, the putative earliest member of Infraorder Brachyura of Early Jurassic age in Great Britain, cannot be accommodated within that infraorder. Numerous characters are inconsistent with placement within Brachyura, including: a lack of fusion of the epistome with the dorsal carapace; chelipeds on the first and putatively ...

Report of brachyuran crabs (Crustacea, Decapoda) from the Pliocene of Borgomanero, Novara (Piedmont, NW Italy)

Natural History Sciences, 2018
Some brachyuran crabs from the Pliocene of a new outcrop nearby Borgomanero (Novara, Piedmont, NW Italy) are reported. This study allows us to recognize a peculiar brachyuran crabs assemblage including: Macropipus cf. M.

Environmental and local habitat variables as predictors of trophic interactions in subtidal rocky reefs along the SE Pacific coast

Ecography, EarlyView.
Temperature generally drives latitudinal patterns in the strength of trophic interactions, including consumption rates. However, local community and other environmental conditions might also affect consumption, disrupting latitudinal gradients, which results in complex large‐scale patterns.

Conserved organ-specific microbial assemblages in different populations of a terrestrial crab

Frontiers in Microbiology, 2023
Microorganisms are ubiquitous in the environment and provide genetic and physiological functions to multicellular organisms. Knowledge on the associated microbiota is becoming highly relevant to understand the host’s ecology and biology.

Crushing and Cutting: Shape Variation and Morphological Integration Between the Claws of Two Swimming Crab Species (Brachyura: Portunidae)

Acta Zoologica, EarlyView.
ABSTRACT This study investigated shape variations and morphological integration between the components of crusher and cutter claws in two species of swimming crabs, Callinectes danae and Callinectes ornatus. The propodi and dactyli of the claws were analysed in males and females of both species, using geometric morphometric techniques to identify ...

An investigation into the diet of elephant fish (Callorhinchus milii) in the waters of Aotearoa/New Zealand

Journal of Fish Biology, EarlyView.
Abstract Chondrichthyans (sharks, rays and chimaeras) are increasingly understood to be an important part of ocean ecosystems, but their ecological role is unclear. Callorhinchus milii (elephant fish) is a chimaera species endemic to Aotearoa/New Zealand and southern Australian waters.

Evidence of Cheliped Autotomy and Regeneration in the Lower Miocene Crab Achelous monspeliensis From Portugal

Ecology and Evolution, Volume 16, Issue 7, July 2026.
Crab autotomy with evidence of regeneration is described for the first time in the fossil record. Autotomy is a defensive behavior that affects more males than females of Achelous monspeliensis and may be related to mating season. ABSTRACT Autotomy—the voluntary shedding of a limb as a defensive response to predation, intraspecific aggression, or ...

An atlas of larval organogenesis in the European shore crab Carcinus maenas L. (Decapoda, Brachyura, Portunidae)

Frontiers in Zoology, 2018
Background The life history stages of brachyuran crustaceans include pelagic larvae of the Zoea type which grow by a series of moults from one instar to the next.
