In the past decade along the U.S. East coast, the overfished western North Atlantic stock of Carcharhinus plumbeus has been recovering; however, research investigating C. plumbeus habitats and seasonal habitat shifts is lacking. Accordingly, we studi

The behavioral responses of free-swimming, wild southern stingrays (Dasyatis americana) and nurse sharks (Ginglymostoma cirratum) to permanent magnets were evaluated in the Florida Keys, USA. Animals were attracted to a baited magnetic treatment boar

The pericardial and peritoneal spaces of elasmobranch fishes are connected by the pericardioperitoneal canal (PPC), which allows pericardial fluid to escape when pressures exceed 0.1–0.3 kPA. Using the horn shark (Heterodontus francisci), we tested
