Short-Term Microplastic Exposure Impairs Cognition in Hermit Crabs [PDF]
Animals, 2023 We tested whether acute microplastic exposure impacts information gathering and processing (cognition) in hermit crabs (Pagurus bernhardus). For five days, we kept 51 hermit crabs in tanks containing either polyethylene microspheres (n = 27) or no ...

Scaling of olfactory antennae of the terrestrial hermit crabs Coenobita rugosus and Coenobita perlatus during ontogeny [PDF]
PeerJ, 2014 Although many lineages of terrestrial crustaceans have poor olfactory capabilities, crabs in the family Coenobitidae, including the terrestrial hermit crabs in the genus Coenobita, are able to locate food and water using olfactory antennae (antennules ...

Marine-dumped waste tyres cause the ghost fishing of hermit crabs [PDF]
Royal Society Open Science, 2021 Poorly managed waste tyres pose serious environmental and health risks, ranging from air pollution caused by fire, leaching of heavy metals and outbreaks of mosquitos, to destruction of vegetation and coral reefs.

Hermit crabs (Pagurus spp.) at their northernmost range: distribution, abundance and shell use in the European Arctic [PDF]
Polar Research, 2015 Hermit crabs are important components of Arctic benthic systems, yet baseline data on their densities and distribution patterns in this rapidly changing region are still scarce.

Polarization vision in terrestrial hermit crabs. [PDF]
J Comp Physiol A Neuroethol Sens Neural Behav Physiol, 2023 AbstractPolarization vision is used by a wide range of animals for navigating, orienting, and detecting objects or areas of interest. Shallow marine and semi-terrestrial crustaceans are particularly well known for their abilities to detect predator-like or conspecific-like objects based on their polarization properties.

Animal contests and microplastics: evidence of disrupted behaviour in hermit crabs
Royal Society Open Science, 2021 Microplastics are ubiquitous in global marine systems and may have negative impacts on a vast range of species. Recently, microplastics were shown to impair shell selection assessments in hermit crabs, an essential behaviour for their survival.

Morphological feminization in hermit crabs (family Paguridae) induced by rhizocephalan barnacles [PDF]
Zoological LettersRhizocephalans (Thecostraca: Cirripedia) are parasitic crustaceans that infect a wide range of decapod hosts, including hermit crabs, crabs, and shrimps.

Weak rappers rock more: hermit crabs assess their own agonistic behaviour. [PDF]
Biol Lett, 2016 Fighting animals use a variety of information sources to make strategic decisions. A neglected potential source of information is an individual’s own performance during a fight.

Phylogenetic synthesis of morphological and molecular data reveals insights on the classification of diogenid hermit crabs (Crustacea: Decapoda: Anomura) [PDF]
PeerJThe family Diogenidae Ortmann, 1892 is a diverse and abundance group of hermit crabs, but their systematics and phylogenetic relationships are highly complex and unresolved.

Multigene molecular systematics confirm species status of morphologically convergent Pagurus hermit crabs. [PDF]
PLoS ONE, 2011 IntroductionIn spite of contemporary morphological taxonomy appraisals, apparent high morphological similarity raises uncertainty about the species status of certain Pagurus hermit crabs.
