Observations on an Aggregation of Grey Reef Sharks and Tools for Photo-Identification—A New Aggregation Nursery Site?
Between 2012 and 2023, using non-invasive photo-identification techniques, 23 specimens of grey reef sharks were identified in the Mozambique Channel off Nosy Be, in an area called “Mokarran”. Some specimens have been re-sighted in this area for up to 1982 days. A probable aggregation and nursery area for this species may have been identified off the coast of Madagascar and, if confirmed, it will be necessary to provide for its protection. Following preliminary underwater observations of about 1000 h carried out monthly between 2012 and 2023 (except the years 2021 and 2022), 23 specimens of grey reef sharks were spotted and photo-identified off the coast of Nosy Be in Madagascar, on an emerging reef called “Mokarran” at a depth between 15 and 30 m. Over 10 years of observations, eight specimens were re-sighted, identified with a non-invasive photo-identification technique of part of the first dorsal and the caudal fin, and one specimen was re-identified after 1982 days from the first sighting, i.e., after more than 5 years. In addition, six specimens of probably pregnant females were also identified in the same area. The population was entirely made up of females. The aggregation area could represent a new nursery site which, if confirmed after further investigations, will require greater protection.

The first recognition of the enigmatic fossil shark genus Megalolamna as the newly designated type species for the genus
Megalolamna is an elusive extinct shark genus (Lamniformes: Otodontidae) previously known from the upper Oligocene-Miocene of the USA, Colombia, Ecuador, Peru, and Japan. Here, we document the first occurrence of Megalolamna from Miocene marine deposits in Europe, specifically from Austria, France, Germany, and Italy. Although the taxon is regarded as a monospecific genus, this study reveals that the species name serotinus has the priority over any previously used names for the taxon and thus redescribes it as Megalolamna serotinus (Probst), comb. nov. This study is also significant because it demonstrates the existence of Megalolamna in the Mediterranean and Paratethys seas during the Miocene. Megalolamna inhabited the tropical-mid-latitudinal zones with spotty but wide geographic distribution. Keywords: Austria, Elasmobranchii , France, Germany, Italy, Neogene, taxonomy
