Regulation of bicarbonate secretion in marine fish intestine by the calcium-sensing receptor [PDF]
, 2018 In marine fish, high epithelial intestinal HCO3- secretion generates luminal carbonate precipitates of divalent cations that play a key role in water and ion homeostasis.

Functional morphology of the pharyngeal teeth of the ocean sunfish, Mola mola
The Anatomical Record, EarlyView.Abstract Many fish use a set of pharyngeal jaws in their throat to aid in prey capture and processing, particularly of large or complex prey. In this study—combining dissection, CT scanning, histology, and performance testing—we demonstrate a novel use of pharyngeal teeth in the ocean sunfish (Mola mola), a species for which pharyngeal jaw anatomy had ...

Frontiers in Behavioral Neuroscience, 2016 Animals use multiple senses during social interactions and must integrate this information in the brain to make context-dependent behavioral decisions. For fishes, the largest group of vertebrates, the mechanosensory lateral line system provides crucial ...

Reactivation of contraction in detergent-lysed teleost retinal cones. [PDF]
, 1982 Teleost retinal cones contract in the light and elongate in the dark. In the green sunfish, Lepomis cyanellus, the necklike myoid region of the cone contracts from as much as 120 micrometers (midnight dark-adapted) to 6 micrometers in fully light-adapted

The valvula cerebelli of the spiny eel, Macrognathus aculeatus, receives primary lateral-line afferents from the rostrum of the upper jaw [PDF]
, 1991 In the spiny eel, Macrognathus aculeatus, anterodorsal and (to a lesser degree) anteroventral lateralline nerves project massively to the granular layer of the valvula cerebelli, throughout its rostrocaudal extent.

The Anatomical Record, EarlyView.A new musculoskeletal reconstruction and revision of the cranio‐mandibular anatomy of the Devonian arthrodire placoderm Dunkleosteus terrelli from a comparative and functional anatomical perspective. Dunkleosteus is a specialized arthrodire with many specializations for feeding on large vertebrates, and many of its features are part of broader ...

Temperature-Mediated Processes in Teleost Immunity: Homeoviscous Adaptation in Teleost Lymphocytes
Experimental Biology and Medicine, 1982 AbstractIn vitro studies with pinfish (Lagodon rhomboides) lymphocytes demonstrated that the temperature to which a fish is acclimated in vivo affects the temperature dependence of lymphocyte responses to mitogenic stimulation with conconavalin A (ConA) in vitro, i.e., at an in vitro temperature of 20°, the lymphocytes of 17° acclimated fish responded ...
