ABSTRACT
The caudal skeleton is one of the most important tools to evaluate teleostean interrelationships, but just the anatomy of few species have been investigated. Black-striped pipefish (Syngnathus abaster) has never been examined for its caudal morphology. Here, red alizaryn is applied as specific staining for calcified structures, providing a better understanding of caudal skeleton organization. Our results and interpretation just partially fit with previous knowledge on other Syngnathus species. This emphasizes both the importance of facing same problems with new technics and methodologies, and the existence of a heterogeneous situation between close-related taxa.
RESUMEN
El esqueleto caudal es una de las más importantes herramientas para evaluar las interrelaciones de teleósteros, pero la anatomía de pocas especies han sido investigada. Nunca se ha estudiado la morfología de la cauda del pez aguja de río de rayas negras (Syngnathus abaster). Se usó una técnica específica de tinción con alizarina roja, para visualizar estructuras calcificadas, obteniéndose un gran conocimiento de la organización del esqueleto caudal. Los resultados e interpretación de ellos coinciden parcialmente con los hallazgos en otras especies de Syngnathus. En ambos casos se enfatiza la importancia de tratar los problemas con nuevas técnicas y metodologías.
