Skeletal Organization of Caudal Fin in Syngnathus abaster (Osteichthyes, Syngnathidae) International Journal of Morphology
Bartolino,Valerio.
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

Collaborative monitoring of the ornamental trade of seahorses and pipefishes (Teleostei: Syngnathidae) in Brazil: Bahia State as a case study Neotropical Ichthyology
Rosa,Ierecê L.; Sampaio,Cláudio L. S.; Barros,Adrianne T..
Many species of seahorses and pipefishes (family Syngnathidae) are traded for medicinal purposes and aquaria; some are also sold as souvenirs or curiosities. Brazil is one of the main suppliers of seahorses for the international aquarium trade, nevertheless, little is known about the magnitude of that trade in the country. With regards to pipefishes, virtually nothing is known about their captures for ornamental purposes in Brazil. The present study assesses the magnitude of captures and trade of seahorses and pipefishes, based on data obtained through a collaborative monitoring program established with the main retailer of marine ornamental organisms in the State of Bahia. The syngnathid fishery is conducted in shallow waters never exceeding 7 m,...
