Meristic Data

Remoras attach to sharks, big fish, and sea turtles and continue their lives with these creatures. Kapızlı and Tekeli beaches are located near Göksu Delta and Anamur nesting areas of Caretta caretta. In this study, two Remora individuals were caught with a fishing rod in July, when the ovulation was most intense. The smaller remora individual (33 cm) was caught from the coast of Tekeli with the chicken breast at a depth of 2.5 m, and the larger one (66 cm) with bread at a depth of 1.5 m from Kapızlı beach on 24.07.2020. The two Remora individuals caught were probably attached to the sea turtles. However, probably due to sea turtles going to the beach to lay eggs, Remoras started to free-swimming, and they were caught with the fishing line since they could not be fed. The present study reported that the first occurrence of Remora specimens is probably attached to turtles for Turkey's northeastern Mediterranean coast. Besides, this study is provided some morphometric and meristic data on this species and discussed a probable host of these specimens.

AbstractAnimal navigation allows individuals to efficiently find and use best available habitats. Despite the long history of research into well-studied taxa (e.g., pigeons, salmon, sea turtles), we know relatively little about squamate navigational abilities. Among snakes, documented philopatry (range maintenance) in a non-colubrid species has been rare. In this study, we document the first example of philopatry and homing in a new world elapid snake, Micrurus apiatus. Our data come from the first multi-year mark-recapture study of this species at the open urban preserve Zoológico Regional Miguel Álvarez del Toro, in Tuxtla Gutiérrez, Chiapas, Mexico. We show that on average snakes returned to within 144 m of their last capture point. By releasing snakes in one location, we noted that recaptured individuals preferentially returned to their last capture location, compared to a distribution of random locations in the park. We conclude with a preliminary discussion of the evolution of snake homing and potential mechanisms.

The morphology of balanomorph barnacles during metamorphosis from the cyprid larval stage to the juvenile has been examined by light microscopy and scanning electron microscopy (SEM). The free-swimming cyprid attaches to a substrate, rotates 90° in the vertical plane, molts, and assumes the adult shape. The resulting metamorph is clad in soft cuticle and has an adult-like appearance with a mantle cavity, thorax with cirri, and incipient shell plates. At some time during the development from cyprid to juvenile, the barnacle begins to mineralize its shell, but it is not known whether calcification occurs before, during, or after ecdysis. To examine this issue, electron probe x-ray microanalysis (EPXMA) was used to detect calcium in cyprids and juveniles at various times during metamorphosis.Laboratory-raised, free-swimming cyprid larvae were allowed to settle on plastic coverslips in culture dishes of seawater. The cyprids were observed with a dissecting microscope, cryopreserved in liquid nitrogen-cooled liquid propane at various times (0-24 h) during metamorphosis, freeze dried, rotary carbon-coated, and examined with scanning electron microscopy (SEM). EPXMA dot maps were obtained in parallel for qualitative assessment of calcium and other elements in the carapace, wall, and opercular plates.
