In an era of global change, thermal biology and ecology are becoming increasingly popular topics in invertebrate research, including molluscs. However, this area of research is still very limited, essentially due to the intrinsic spatial limitations of traditional single-point temperature measurements (e.g. thermocouples, iButtons and infrared thermometers). This is not the case, however, with infrared thermography, which has the desirable attribute of producing images that allow for… 
Snails in the sun: Strategies of terrestrial gastropods to cope with hot and dry conditions
TLDR
Future work on this subject requires multicausal thinking to account for the complexity of relationships involved in snails' adaptation to insolation, heat, and drought, as well as research gaps and questions that remained unanswered.
Where three snail species attach while emersed in relation to heterogenous substrate temperatures underneath intertidal boulders
TLDR
The results suggest that gastropod thermoregulatory behaviour is far more complex than simply retreating underneath boulders at low tide, as there is also a range of under-boulder temperatures that they interact with.
Rocks of different mineralogy show different temperature characteristics: implications for biodiversity on rocky seashores
As some intertidal biota presently live near their upper tolerable thermal limits when emersed, predicted hotter temperatures and an increased frequency of extreme-heat events associated with global
Morphometric analysis of the shell of the intertidal gastropod Echinolittorina lineolata (d'Orbigny, 1840) at different latitudes along the Brazilian coast
TLDR
Of the morphometric variables, the length and the width of the shell were the most representative variables that influenced the gastropods in the different latitudes and were also different in males and females, with females having larger shell lengths and widths across all latitudes.
Species density and morphometric variation of species belonging to Conus (Gastropoda: Conidae) genera in the coastal waters of Ambon Island, Indonesia
Abstract. Tebiary LA, Leiwakabessy F, Rumahlatu D. 2022. Species density and morphometric variation of species belonging to Conus (Gastropoda: Conidae) genera in the coastal waters of Ambon Island,
Relationship between contrasting morphotypes and the phylogeny of the marine gastropod genus Tegula (Vetigastropoda: Tegulidae) in East Asia
TLDR
The findings show that shell sculpture is not a reliable character to use for species delimitation in Tegula, and suggest that differences in habitat preferences may potentially drive the genetic divergences seen in this group.
Movement patterns of the epizoic limpet Lottia tenuisculpta on two host snails Omphalius nigerrimus and Reishia clavigera
TLDR
The tiny epizoic limpet Lottia tenuisculpta lives on rocky surfaces and shells of the snails Omphalius nigerrimus and Reishia clavigera and the potential role of this behaviour in creating home scars is discussed.

TLDR
Results indicate a highly intricate pattern of thermal stress, where the interaction of climate with the dynamics of the tidal cycle determines the timing and magnitude of temperature extremes, creating a unique “thermal signal” at each site.
Temperature relationships of some tropical Pacific intertidal gastropods
TLDR
A very important factor in the temperature regulation of intertidal snails appears to be the extent of the area of contact between the animal and the substratum, which is greatest in limpets and least (negligible) in littorinids.
Infrared thermography in marine ecology: methods, previous applications and future challenges
TLDR
The aim of this paper was to summarise the rapidly growing application of IRT in marine ecology, to discuss best practises for using I RT in the marine environment whilst outlining some common limitations, and to suggest future research directions.
Thermal Stress in a High Shore Intertidal Environment: Morphological and Behavioural Adaptations of the Gastropod Littorina africana
Thermal stress, coupled with desiccation, is one of the major physical hazards to be overcome by intertidal organisms. Biogeographic trends are generally temperature mediated (eg. Brown and Jarman,
Importance of Behavior and Morphological Traits for Controlling Body Temperature in Littorinid Snails
TLDR
A mechanistic heat-budget model is used to compare the effects of behavioral and morphological traits on the body temperatures of five species of littorinid snails under natural weather conditions and indicates that, for all five species, the relative contribution of shell color or sculpturing to temperature regulation is small.
Behavioral thermoregulation of the tuatara, sphenodon punctatus, under hydric and digestive constraints
TLDR
Experimental evidence is provided that reptiles are capable of adjusting their habitat selection behavior in response to differing humidity constraints and that those choices may change with the metabolic requirements of digestion.
Thermal ecology on an exposed algal reef: infrared imagery a rapid tool to survey temperature at local spatial scales
TLDR
The results support the utility of IR thermography in exploring thermal ecology, and demonstrate the steps needed to calibrate data leading to establishment of baseline conditions in a changing and heterogeneous environment.
Microhabitats in the tropics buffer temperature in a globally coherent manner
TLDR
The need for a next generation of predictive models that account for species' ability to move within microhabitats to exploit favourable buffered microclimates is illustrated.
The role of temperature and desiccation stress in limiting the local‐scale distribution of the owl limpet, Lottia gigantea
TLDR
The combination of direct measurements of sub-lethal and lethal temperature thresholds using realistic stress exposures and predictions from a heat-budget model give insight into the role of thermal disturbance in affecting the local-scale distributions of intertidal organisms.
