Hermit crabs, shells, and sentience

RW Elwood - Animal cognition, 2022 - Springer
Hermit crabs have an intimate relationship with gastropod shells and show numerous
activities by which they locate, select, and change shells in different contexts. They gather …

Metabolic and behavioural effects of hermit crab shell removal techniques: Is heating less invasive than cracking?

LM Burciaga, G Alcaraz - Animal Welfare, 2023 - cambridge.org
Hermit crabs (Paguroidea; Latreille 1802) offer great opportunities to study animal behaviour

What motivates hermit crabs to abandon trapped shells? Assessing the influence of shell value, olfactory attractants, and previous experience

D Gorman, F Barros, A Turra - Hydrobiologia, 2015 - Springer
Hermit crabs finding themselves in a trapped shell face a critical decision that will require an
assessment of the benefits of abandonment against the increased risks of predation and …

Risk-taking and risk-avoiding behaviors by hermit crabs across multiple environmental contexts

D Gorman, MN Ragagnin, ID McCarthy… - Journal of Experimental …, 2018 - Elsevier
