Electroreception in marine fishes: chondrichthyans.
Level 5 - mechanism / opinion, no new human data
Level 5 by design analogy; narrative review of non-human sensory biology without systematic search criteria.

What was done
The authors conducted a narrative review summarizing the history, receptor morphology, peripheral and central nervous system physiology, and behavioral roles of passive electroreception in marine chondrichthyans (sharks, skates, rays, and chimaeras), alongside the potential contributions of genomic and molecular approaches.
What was found
The abstract provides no quantitative data or specific numerical metrics. It summarizes qualitative domain knowledge regarding morphological adaptations across taxa and habitats, neural pathways mediating passive electroreception, and mediated behaviors, while highlighting emerging genetic tools.
Why it matters
It synthesizes the fundamental sensory biology of elasmobranch electroreception and frames key questions regarding how marine species will respond to anthropogenic electromagnetic perturbations.
Limits
The abstract describes a non-systematic narrative review with no defined search strategy, sample size, or quantitative meta-analytic data. It lacks specific empirical findings on the magnitude of behavioral or physiological disruption caused by anthropogenic fields.
