New Paper: Results support mitochondrial genetic continuity across Western Atlantic electric ray-Narcine populations. 🦑🧪🐟🧬🦈 link.springer.com/article/10.1...
Mitogenomic and phylogenomic analyses identify a cohesive Western Atlantic lineage within the Narcine complex (Torpediniformes: Narcinidae) - Molecular Biology Reports
Background Accurate species delimitation within electric rays of the genus Narcine has been hindered by overlapping morphological characters and limited molecular resolution in previous single-locus s...

This year’s theme, Collaboration, reflects exactly what manta conservation requires.
Manta rays move across borders and depend on particular places to feed, clean, aggregate, and reproduce.
