Predation and Crypsis in the Evolution of Electric Signaling in Weakly Electric Fishes

Frontiers in Ecology and Evolution, 2019
Eavesdropping by electroreceptive predators poses a conflict for weakly electric fish, which depend on their Electric Organ Discharge (EOD) signals both for navigation and communication in the dark.

Electric imaging through evolution, a modeling study of commonalities and differences. [PDF]

PLoS Computational Biology, 2014
Modeling the electric field and images in electric fish contributes to a better understanding of the pre-receptor conditioning of electric images. Although the boundary element method has been very successful for calculating images and fields, complex ...

Comparable ages for the independent origins of electrogenesis in African and South American weakly electric fishes. [PDF]

PLoS ONE, 2012
One of the most remarkable examples of convergent evolution among vertebrates is illustrated by the independent origins of an active electric sense in South American and African weakly electric fishes, the Gymnotiformes and Mormyroidea, respectively ...

The Astonishing Behavior of Electric Eels

Frontiers in Integrative Neuroscience, 2019
The remarkable physiology of the electric eel (Electrophorus electricus) made it one of the first model species in science. It was pivotal for understanding animal electricity in the 1700s, was investigated by Humboldt and Faraday in the 1800s, was ...

Multisensory integration and behavioral plasticity in sharks from different ecological niches.

PLoS ONE, 2014
The underwater sensory world and the sensory systems of aquatic animals have become better understood in recent decades, but typically have been studied one sense at a time.

Synapsids and sensitivity: Broad survey of tetrapod trigeminal canal morphology supports an evolutionary trend of increasing facial tactile specialization in the mammal lineage

The Anatomical Record, EarlyView.
Abstract The trigeminus nerve (cranial nerve V) is a large and significant conduit of sensory information from the face to the brain, with its three branches extending over the head to innervate a wide variety of integumentary sensory receptors, primarily tactile.

Sensory Biology of the Franciscana (Pontoporia blainville, Pontoporiidae, Cetartiodactyla): Ontogenetic Modifications of Vibrissae and Vibrissal Crypts

Integrative Zoology, EarlyView.
The transition of cetaceans from a terrestrial to an aquatic environment involved a crucial sensory adaptation to environments with limited visibility. Vibrissae, important mechanoreceptors, undergo an ontogenetic transformation in odontocetes. This research describes the histomorphology of vibrissae and crypts at different developmental stages ...

Smart Hydrogel Tactile Sensors and Systems: A Comprehensive Review

SmartSys, Volume 1, Issue 4, December 2025.
ABSTRACT The rise of wearable electronics and intelligent robotics has created an urgent demand for tactile sensors that are soft, biocompatible, and responsive. Hydrogels, with high water content and mechanical compliance such as biological tissues, provide a unique platform for constructing next‐generation tactile sensors that mimic human skin’s ...

Surface morphology and distribution of oropharyngeal taste papillae in sharks and rays (Elasmobranchii, Chondrichthyes): Implications for gustatory sensitivity

Journal of Anatomy, Volume 247, Issue 5, Page 924-952, November 2025.
This study investigates the morphology, abundance, and distribution of taste papillae in the oropharyngeal cavity of a range of elasmobranchs using SEM, histology, and topographic analyses. The interspecific importance of gustation is reflected in quantitative differences in the size, density, and distribution of taste papillae, which have implications

Body Size and Thermal Sensitivity of a Facultative Air‐Breathing Fish Amidst Environmental Change

Ecology of Freshwater Fish, Volume 34, Issue 3, July 2025.
ABSTRACT Many freshwater fish populations are increasingly required to respond to warming waters and low dissolved oxygen concentrations as a result of land‐use change and climate change. In addition, the average size of fish in harvested populations can be drastically reduced due to heavy fishing pressure.
