The state of knowledge on four families of Syngnathoidei fishes (Teleostei: Syngnathiformes): Aulostomidae, Centriscidae, Fistulariidae and Solenostomidae

Journal of Fish Biology, EarlyView.
Abstract Knowledge on the ecology and life‐history traits of coastal marine species is vital to inform their conservation and management, especially as their coastal habitats come under increasing threats. However, such data have never been collated for four of the five families in the suborder Syngnathoidei—the close relatives of the better‐studied ...

Bony fish genomes: Status and gaps

Journal of Fish Biology, EarlyView.
Abstract Bony fish constitute an exceptionally species‐rich group of aquatic vertebrates, comprising more than 95% of all living fish. The adaptive processes on the diversity of environments they inhabit make them a highly diverse group from taxonomic, morphological and evolutionary standpoints.

First record of young‐of‐the‐year smooth hammerhead (Sphyrna zygaena) in coastal waters of Galicia, northwest Spain

Journal of Fish Biology, EarlyView.
Abstract The smooth hammerhead (Sphyrna zygaena) is typically considered an oceanic species and is only rarely observed in the cooler coastal waters of the northeastern Atlantic. On 20 December 2024, a juvenile S. zyganea was captured at 25 m depth in the inner Ría de Pontevedra (Rías Baixas, northwest Spain).
