A great week for e-fish papers! In this one Poon & Crampton show that electric eels predators suppress their low-voltage electrolocation EODs when hunting weakly electric gymnotiform prey which in turn suppress theirs to hide from the eels. Cool stuff! doi.org/10.1016/j.cu...

Landscape Evolution Drives Continental Diversification in Neotropical Freshwater Fishes of the Family Erythrinidae (Teleostei, Characiformes) Conde-Saldaña et al. @gymnotus.bsky.social 2025 Journal of Biogeography doi.org/10.1111/jbi.... Shows connection between evolutionary history and geology.
FIGURE 4 | Estimated mean dates for biogeographic events in Erythrinidae on tectonically active (Western) and passive (Eastern) continental
margins. (A) Phylogenies of species in erythrinid genera from Figure 2A. Numbered circles represent biogeographic events dated using the geological
literature (Table S3). Lettered tip labels represent biogeographic areas on the map. Red numbers at tree nodes represent mean divergence time esti-
mates (Ma). (B) Lineage-age distribution of biogeographic events for clades in Panel A. Estimates are reported for minimum, median and maximum
(mean dates from Figure 1) event age (Table S3). Ages of tectonic uplifts are indicated by horizontal rose bars. Note pulsed-age distribution of bio-
geographic events in clades on the active Western margin, while the more continuous age distribution of events on the passive Eastern margin. Note
opposite directions of watershed migration and geodispersal routes. Fish photographs: Hoplias and Erythrinus (Martin Taylor) and Hoplerythrinus

Turns out the Snail Darter, which halted a TVA dam’s construction in the first major test of the Endangered Species Act, was never a distinct species. All species descriptions are hypotheses open to testing.
