Pregnancy has been traditionally defined as the period during which developing embryos
are incubated in the body after egg–sperm union. Despite strong similarities between …

The seahorses, pipefishes and seadragons (Syngnathidae) are among the few vertebrates
in which pregnant males incubate developing embryos. Syngnathids are popular in studies …

The goal of this review was to provide a historical overview of how molecular techniques
have increased the understanding of the ecology and evolution of the family Syngnathidae …

Uniquely among vertebrates, seahorses and pipefishes (Family Syngnathidae) incubate
their eggs within a male brood pouch. This has contributed to a widespread, but poorly …

Testes, spermatogenesis and sperm morphology have been analysed in four species of the
Syngnathus genus. All species show testes of unrestricted lobular type, characterized by a …

Testes morphology, spermatogenetic process and mature sperm ultrastructure were
analysed in Hippocampus guttulatus, using both light and transmission electron microscopy …

Osteoglossiformes are an order of “bony tongue” fish considered the most primitive living
order of teleosts. This review seeks to consolidate known hypotheses and identify gaps in …

Like seahorses, some of the closely-related pipefish species (Family Syngnathidae)
incubate their eggs within a male brood pouch. This has contributed to considerable …

Lagoons and estuaries are transition spaces between earth and sea. Beyond their expanse,
geographic repartition, geomorphological, hydroclimatic and ecobiological diversity and …

Les lagunes et les estuaires sont des espaces de transition entre la terre et la mer. Au-delà
de leur étendue, de leur large répartition géographique, de leur diversité …
