While morphological abnormalities have been widely reported in batomorphs, ontogenetic deformities of the posterior pectoral fin are rare. In this paper, we present a bluespotted ribbontail ray, (Forsskål, 1775), with symmetrically deformed posterior pectoral fins. The specimen was observed through aerial imagery on a coastal sandflat in the central Red Sea (22.

- Climate change is causing shifts in animal habitats, particularly affecting the distribution of threatened marine species like whale sharks.
- Projections indicate that by 2100, whale sharks could lose more than 50% of their core habitat in some areas, with significant geographic shifts that could place them in closer proximity to large ships.
- The increase in whale shark interaction with shipping is expected to be dramatically higher under high emission scenarios compared to sustainable development, highlighting the urgency for better climate-threat predictions in conservation strategies for endangered marine life.
Background: Spetzler-Martin (SM) Grade III brain arteriovenous malformations (BAVMs) represent a transitional risk zone between low- and high-grade BAVMs, characterized by diverse angioarchitecture. The primary treatment options are endovascular embolization, microsurgical resection (MS), and stereotactic radiosurgery (SRS). This study compares the efficacy and outcomes of MS and SRS.

- Latin America's genetic diversity offers a unique opportunity to study Alzheimer's disease (AD) and frontotemporal dementia (FTD), with a focus on identifying related genetic variations.
- The study involved 2,162 participants from six countries who underwent extensive genomic sequencing and analysis to detect genetic factors linked to these dementias.
- Results highlighted a mix of American, African, and European ancestries, discovered 17 pathogenic variants, and revealed specific genetic variations tied to AD and FTD inheritance patterns in affected families.
