Side-by-Side Comparison
| Feature | rana | ruano |
|---|---|---|
| Definition | Cualquiera de varios centenares de especies de batracios anuros, sobre todo aquellos de la familia Ranidae. Se caracterizan por un cuerpo corto y robusto, carente de cola, con las patas traseras largas y musculosas para permitir el salto, la presencia de membranas interdigitales en las cuatro extremidades, ojos protuberantes, y una piel lisa y de aspecto húmedo. Aunque el color considerado típico es el verde, existen ranas de coloraciones muy diferentes, incluyendo vistosos amarillos, rojos y azules en algunas especies que secretan alcaloides venenosos. Los juveniles son similares a alevines, y de hábitat acuático, mientras los adultos son plenamente anfibios y se desplazan con facilidad en tierra, siendo muchas especies trepadoras. La diferencia con los sapos es coloquial y basada en la apariencia lisa de las ranas contra la rugosa de estos últimos, pero no tiene base taxonómica. | Variante de roano (caballo de pelaje grisáceo). |
