    Résumé

    The speartooth shark Glyphis glyphis is found in Australia and Papua New Guinea, and it was never reported beyond this extension range. The present paper provides the first register of this species outside its known distribution. We collected one of G. glyphis in 2018 at Digul River, Mapi district, Papua province, Indonesia. This record represents the first known occurrence of this species in Indonesia, and an extension of its original geographical distribution in about 250 km north. Registers of new localities for G. glyphis were based on photographs.

    Résumé

    Fossil remains, including a vertebral centrum and some scales, from the Lower Cretaceous Marizal Formation of the Tucano Basin are described as belonging to  an amiid fish likely of the subfamily Vidalamiinae. A comparison made from the largest midline predorsal scale with scales in several species of amiids suggests a standard length of approximately 1400 mm for the Marizal Formation’s species. This amiid represents the largest fossil fish known from the Marizal ichthyofauna in the palaeobiota and likely was an apex predator.

    Résumé

    Nine species of marine fishes are recorded from Réunion Island for the first time, observed during a faunal inventory under MesoRun program. These species, Dunckerocampus boylei Kuiter 1998 (Syngnathidae), Luzonichthys waitei (Fowler, 1931) (Serranidae), Plectranthias winniensis (Tyler, 1966) (Serranidae), Ostorhinchus fukuii (Hayashi, 1990) (Apogonidae), Hoplolatilus cuniculus Randall & Dooley, 1974 (Malacanthidae), Pterocaesio lativittata (Carpenter, 1987) (Caesionidae), Halichoeres trispilus Randall & Smith, 1982 (Labridae), Priolepis nocturna (Smith, 1957) (Gobiidae) and Canthigaster tyleri Allen & Randall, 1977 (Tetraodontidae) were photographed in the lower mesophotic zone (70 – 110 m depth). Two other species Chromis sp. (Pomacentridae) and Gymnothorax aff. breedeni McCosker & Randall, 1977 (Muraenidae) are also reported from Réunion for the first time. New depth records are provided for Luzonichthys waitei (102 m), Ostorhinchus fukuii (100 m), Pterocaesio lativittata (100 m), Halichoeres trispilus (110 m), Priolepis nocturna (97 m) and Canthigaster tyleri (85 m). The ichthyological biodiversity in the mesophotic zone in the southwestern Indian Ocean, especially within mesophotic coral ecosystems, has been poorly studied. More thorough sampling efforts would probably result in the description of new species and additional new records.

    Résumé

    The present study contributed to report the Hippocampus patagonicus Piacentino and Luzzatto 2004 occurrence in shallow rocky reefs. We found two individuals in two different Guaíba Island beaches, Sepetiba bay, Rio de Janeiro, Brazil. We recorded two adults with similar morphometry as reported in other studies with the same species. They are not usually found in shallow waters, but the present study reported them associated with rocky reefs less than one meter deep. This is the first record for the species in that environment and in Sepetiba Bay.
