Pempheris Mangula
''Pempheris mangula'', the black-edged sweeper, Moluccan sweeper or black-margin bullseye is a species of Indo-Pacific sweeper from the family Pempheridae. The history of the identification of the Indo-Pacific sweepers is complex and this species has been identified as the ''"Pempheris vanicolensis"'' which has colonised the Mediterranean Sea from the Red Sea via the Suez Canal by Lessepsian migration but this identification is not universally accepted.

Only the tip of the dorsal fin is blackish. The very large eye has a diameter which is equal to 13.0-15.3% of the standard length and 43.6-51.5% of the head length.

Cuvier was a major figure in natural sciences research in the early 19th century and was instrumental in establishing the fields of comparative anatomy and paleontology through his work in comparing living animals with fossils. Cuvier's work is considered the foundation of vertebrate paleontology, and he expanded Linnaean taxonomy by grouping classes into phylum, phyla and incorporating both fossils and living species into the classification. Cuvier is also known for establishing extinction as a fact—at the time, extinction was considered by many of Cuvier's contemporaries to be merely controversial speculation. In his ''Essay on the Theory of the Earth'' (1813) Cuvier proposed that now-extinct species had been wiped out by periodic catastrophi ...
