Acclimation from marine to dilute environments constitutes among the dramatic evolutionary transitions in the history of life. Such adaptations have evolved in multiple lineages, but studies of the blood/hemolymph homeostasis mechanisms are limited to those using evolutionarily advanced Deuterostome (chordates) and Ecdysozoa (crustaceans). Here, we examined hemolymph homeostasis in the advanced Lophotrochozoa/mollusc, the other unexplored taxa, and its possible regulation by the vasopressin… 
Salinity induced alterations in ionic concentration of haemolymph and its effects on histopathology of gills and digestive gland in razor clam (Solen dactylus von Cosel, 1989; Bivalvia, Solenidae)
TLDR
Histopathological analysis showed severe tissue damage at low salinities with expanded intercellular spaces, an increase of intracytoplasmic vacuoles in the digestive tubules, and necrosis and destruction of lamellae in gill tissues.
Hyperosmotic tolerance of adult fish and early embryos are determined by discrete, single loci in the genus Oryzias
TLDR
Results indicate that a maternal factor governs embryonic hyperosmotic tolerance and maps to a locus distinct from that associated with adult hyperosMotic tolerance.
Paralarvae of Octopus vulgaris Type II are stenohaline conformers: relationship to field distribution and dispersal
The degree of euryhalinity of cephalopod planktonic paralarvae potentially affects the dispersal capacity and distributional range of species. Herein, we tested the hypothesis that O. vulgaris Type
Transcriptomic response to three osmotic stresses in gills of hybrid tilapia (Oreochromis mossambicus female × O. urolepis hornorum male)
TLDR
A global overview of gene expression patterns and pathways that related to osmoregulation in hybrid tilapia could contribute to a better understanding of the molecular regulation mechanism in different osmotic stresses.
Disparate responses to salinity across species and organizational levels in anchialine shrimps
TLDR
Responses to salinity change at multiple organizational levels in five species of shrimp representing at least three independent invasions of the anchialine ecosystem show wide variation in response to fluctuating salinity at the whole-animal, tissue and molecular level.
Comparative and Evolutionary Physiology of Vasopressin/ Oxytocin-Type Neuropeptide Signaling in Invertebrates
TLDR
The comparative physiology of VP/OT-type neuropeptides in invertebrates is reviewed, with roles in regulation of reproduction, feeding, and water/salt homeostasis emerging as common themes and recent reports of roles inregulation of oocyte maturation in the sea-squirt, extraoral feeding behavior in the starfish Asterias rubens and energy status and dessication resistance in ants are highlighted.
Highly diversified expansions shaped the evolution of membrane bound proteins in metazoans
TLDR
The possible LHCA membrane proteome is defined and the fundamental functional clusters that underlie metazoan diversity and innovation are described.
Molecular cloning and distribution of oxytocin/vasopressin-like mRNA in the blue swimming crab, Portunus pelagicus, and its inhibitory effect on ovarian steroid release.
TLDR
The knowledge gained from this study will provide more understanding on neuro-endocrinological controls in this crab species and strong molecular conservation of the PpelOT/VP-like peptide with those of other animals.
Drivers of octopus abundance and density in an anchialine lake: A 30 year comparison
TLDR
Given the ecosystem's unique and closed ecological community and the population dynamics and distribution drivers, Sweetings Pond has the potential to act as a ‘natural laboratory’ to explore further questions about marine insular systems and their influence on species populations in terms of ecological and behavioural change.
Marine Structural Protein Stability Induced by Hofmeister Salt Annealing and Enzymatic Cross-Linking.
TLDR
Understanding secondary structure changes caused by aqueous and ionic environments can be instructive for the tuning of the suckerin film sclerotization, its conversion to a tough biological material, and to ultimately produce the natural squid sucker ring teeth.

TLDR
Results of the hemolymph osmotic and ionic status indicate that G. depressus is able to adapt for more than 10 days in these salinities and for 2 days under terrestrial conditions.

TLDR
The hypothesis that the energy budget of adult cephalopods is not significantly compromised during long-term exposure to moderate environmental hypercapnia is supported, however, the downregulation of ion regulatory and metabolic genes in late-stage embryos, taken together with a significant reduction in somatic growth, indicates that cepinghalopod early life stages are challenged by elevated seawater Pco(2).
Development in a naturally acidified environment: Na+/H+-exchanger 3-based proton secretion leads to CO2 tolerance in cephalopod embryos
TLDR
Using cephalopod molluscs as an invertebrate model this work provides important insights regarding the unifying evolutionary principles of pH regulation in different animal taxa that enables them to cope with CO2 induced acid–base disturbances.

TLDR
A large suite of potential endocrine control mechanisms have been identified, and recent evidence suggests that paracrines such as endothelin, nitric oxide, and prostaglandins might also control MRC function.
A structure-function analysis of ion transport in crustacean gills and excretory organs.
TLDR
The diversity of structural architectures encountered in different crustacean gill types, and in constituent cell types are addressed, before examining the physiological mechanisms of Na(+), Cl(-), Ca(2+) and NH(4)(+) transport, and of acid-base equivalents, based on findings obtained over the last two decades employing advanced techniques.
Ion Regulation in Invertebrates: Molecular and Integrative Aspects*
TLDR
This overview discusses mechanisms of metal detoxification and the presence of Cl‐ATPase in marine organisms to avoid excess intracellular Cl−; Ca2+ regulation and endocrine aspects of adaptations to transitional (semiterrestrial) environments; adaptations to Ca2+, particularly the reabsorption through specific transporters found in the urine; and ionoregulatory mechanisms for life on land.

TLDR
Crustacean hyperglycaemic hormone (CHH) has now been confirmed to have effects on hydromineral regulation, and a putative role for neuropeptides in salt and water balance suggests that current models for salt regulation are probably incomplete.

TLDR
The results show that the nutritional state of an animal is important in modulating its physiological responses to environmental perturbations, and underscores the importance of studying physiological responses at the whole organism level under conditions closely approximating those of the natural environment.
