Mexican Tetra
Astyanax mexicanus
A freshwater fish with both surface and cave-dwelling populations, used to study evolution and adaptation.
Dataset Statistics
Overview
Mexican Tetra (Astyanax mexicanus) is a remarkable model organism for evolutionary biology, cave adaptation, and developmental genetics research. This species exists in two distinct forms: surface-dwelling populations and cave-dwelling populations that have independently evolved unique adaptations including eye degeneration, pigmentation loss, and enhanced metabolic efficiency. This portal provides comprehensive genomic resources for studying the molecular mechanisms underlying evolutionary adaptation and phenotypic diversification.
Research Areas Covered
- Evolutionary Biology: Cave adaptation, surface vs. cave population differences
- Metabolic Adaptation: Energy metabolism, nutrient sensing pathways
- Comparative Genomics: Cis-regulatory changes underlying adaptive evolution
