The clustering behavior and cluster composition of hermit crabs as well as the patterns of shell utilization of clustered and scattered individuals were studied. This study was conducted in the intertidal region of Grande Beach, São Sebastião, southeastern Brazil. Samples were taken both in randomized transects and 1 m2 quadrats during low tide periods. Crabs were counted, measured (shield length), and sexed. Shells were identified and had their adequacy and condition (physical damage and… 
Reproductive behavior of intertidal hermit crabs (Decapoda, Anomura) in southeastern Brazil
TLDR
Male to male agonistic encounters over females and guarding behavior were more common to C. sclopetarius and C. vittatus while Pagurus criniticornis, which courted successfully as males fertilizing females' eggs, were demonstrated to be intersex, with both male and female gonopores.
SHELL UTILIZATION PATTERNS OF A TROPICAL ROCKY INTERTIDAL HERMIT CRAB ASSEMBLAGE: I. THE CASE OF GRANDE BEACH
TLDR
There was a tendency toward high numbers of ovigerous females in relatively lighter and small-aperture shells, such as Cerithium atratum and Morula nodulosa, which was associated with growth restriction and low fecundity imposed by shell morphology.
Characterization of the occupied shells by the hermit crab Clibanarius vittatus (Decapoda, Diogenidae) at Baixio Mirim tideflat, Guaratuba Bay, southern Brazil.
TLDR
The successful establishment of C. vittatus at Baixio Mirim is mainly due to the appropriately shaped and wide range of size of S. haemastoma shells that were most often occupied by the hermit crabs of the studied population.

Coexisting hermit crabs may competitively interact for shells and microhabitats, mainly when shell availability is habitat-related. Three species of Clibanarius (C. antillensis, C. sclopetarius, and
Ecology of subtropical hermit crabs in SW Madagascar: refuge-use and dynamic niche overlap
TLDR
The results indicate that the SW Madagascar hermit crab assemblage is a speciose guild with (5D) niche complimentarity and temporally dynamic niche overlap.
Richness, abundance and shell use of subarctic and arctic hermit crabs
TLDR
These hermit crabs probably represent the least rich assemblage, with the lowest and most patchy typical abundances reported to date and are amongst the smallest individuals using the least diverse and most damaged gastropod shells.
Shell condition and adequacy of three sympatric intertidal hermit crab populations
TLDR
Fecundity of the crabs of this assemblage is thought not to be limited by shell use once ovigerous females are occupying optimal shells, while the smallest individuals in the populations used relatively heavier shells.

TLDR
This study describes the daily activity in a simulated high tide situation of four species of hermit crabs that coexist in an intertidal flat in southeastern Brazil, and shows high activity not influenced by day/night conditions during the entire observed period.

Field observations on activity and clustering in two intertidal hermit crabs, clibanarius virescens and calcinus laevimanus (Decapoda, Anomura)
TLDR
Activity and clustering in two intertidal species of hermit crabs were studied during a semilunar tide cycle in Somalia, suggesting that the clustering habit is exclusive to crabs which either need to frequently change their shells or are exposed to the air.
Tidal clustering and dispersal of the hermit crab Clibanarius digueti
At Puerto Penasco, Sonora, Mexico, field observations indicate that C. digueti exhibits a tidal rhythm of clustering and dispersal. Upon exposure, up to 700 individuals assemble in tight clusters
Hermit crabs (Crustacea: Decapoda: Anomura), gastropod shells and environmental structure: their relationship in southeastern Brazil
TLDR
Shell utilization and availability varied among sites and shell utilization seemed to be dependent on differences in local shell supply (size and abundance of living snails) and preferences of the hermit crabs for certain shell types.
Social behavior of the Paguridae and Diogenidae of Curaçao
TLDR
Measurements of shell-fighting pairs of Clibanarius tricolor indicated that smaller individuals very rarely win over larger crabs, females have a slight advantage in shell-fights and that recently moulted crabs are both more likely to be attacked and more likely than not to lose when attacked.
Movement patterns and dispersal of the hermit crab Clibanarius longitarsus in a mangrove swamp
TLDR
The spatial strategy of the hermit crab Clibanarius longitarsus was studied during a semilunar tidal cycle in a mangrove swamp in Kenya, finding that animals maintained the same locomotory sense during single HWs, and over subsequent HWs.
Behavioral Adaptations of Intertidal Hermit Grabs
TLDR
The behavioral patterns associated with living in shells which permit the shell to serve as a microhabitat constitute the major adaptation enabling the hermit crabs to exploit the intertidal environment so successfully.
The adaptive significance of clustering in the hermit crab Clibanarius digueti
TLDR
Results suggest that aggregation improves survivorship of extreme cold and desiccation and may also enable C. digueti to resist displacement by strong currents.
Hypotheses on proximate and ultimate factors influencing clustering in the tropical hermit crab Clibanarius laevimanus
Proximate and ultimate factors influencing clustering behaviour in the mangal-dwelling hermit crab Clibanarius laevimanus Buitendijk 1937 were studied in Kenya. First, a reasonable hypothesis to un...
