  • First record of the oceanic puffer Lagocephalus lagocephalus (Linnaeus, 1758) from the Syrian marine waters (eastern Mediterranean)
    Marine Biodiversity Records, 2019
    Co-Authors: Firas Alshawy, Amir Ibrahim, Chirine Hussein, Murhaf Lahlah
    Abstract:

    Background The puffer fish species (Tetraodontidae) inhabit tropical and subtropical coastal waters around the world, and some species exist in many parts of the Mediterranean Sea. In the Syrian marine waters (eastern Mediterranean), five species are known to exist but Lagocephalus lagocephalus (Linnaeus, 1758) was not recorded there before. Method Samples were collected from a depth of 300 m off Banyas coast, Syria, using bottom longline, the morphometric measurements and meristic measurements were recorded. Results One specimen of the oceanic puffer Lagocephalus lagocephalus (Linnaeus, 1758) was caught from the marine water of Syria. Conclusion This is the first record of Lagocephalus lagocephalus (Linnaeus, 1758) in the Syrian marine waters.

  • how small puffers teleostei Tetraodontidae swim
    Ichthyological Research, 2003
    Co-Authors: I. Plaut, Tamar Chen
    Abstract:

    The tetraodontiform swimming mode has recently attracted attention because puffers swim very steadily and, unlike most of the other median and paired fin (MPF) swimmers, use more than one pair of fins to propel themselves through the water. To date, only one study presenting data concerning the swimming kinematics of puffers has been published, and this study dealt only with two species of large body size. In the present study, the swimming kinematics of small puffers (<6 cm TL) Tetraodon schoutedeni is described and compared to the swimming kinematics of larger puffers and boxfish. The results show that, generally, the swimming kinematics of small puffers is similar to that of larger puffers. The main differences that were found are in the synchronization of dorsal and anal fin motion, and in the motion of the pectoral fins, which complete their adduction before the dorsal and anal fins do. Maximum fin beat frequency was 18.4 Hz, much faster than that of larger puffers. At slow and median swimming speeds, dorsal fin beat amplitude increases with swimming speed and then remains constant between median and fast swimming speeds. The results confirm previous findings that puffers swim extremely steadily. Most of the differences in swimming kinematics between large and small puffers can be attributed to the size differences, but the difference in fin synchronization should be further studied to be completely understood.

  • How puffers (Teleostei: Tetraodontidae) swim
    Journal of Fish Biology, 1996
    Co-Authors: Malcolm S. Gordon, I. Plaut, D. Kim
    Abstract:

    Two species of marine Indo-Pacific puffers, Arothron meleagris and A. nigropunctatus, were filmed with a high-speed motion picture camera while swimming in a Brett-type water tunnel at speeds of 1-3.5 body lengths (BL) s−1. The puffers generated thrust by use of their pectoral fins in addition to their dorsal and anal fins; the long axis of the body tilted, mouth upwards, by 3–10) while the fishes swam; antero-ventral body profiles of the fishes changed as swimming speeds increased; pectoral fins undulated and moved 180) out of phase from each other, while dorsal and anal fins oscillated in phase with each other; frequencies of fin movements (F) increased linearly in relation to swimming speeds (Uc(rel)) and were described by the equation F=1.48 Uc(rel)+1.66; stride lengths also increased at higher Uc(rel); and, at swimming speeds above 3.0 BL s−1 puffers began to move their tails in sub carangiform-like modes of burst swimming. These results modify significantly the accepted view of the tetraodonti form mode of median and paired fin swimming.
