First Occurrence of Heniochus intermedius Steindachner, 1893 in The Syrian Marine Waters (Levantine Basin)

On May 18, 2022, a Heniochus intermedius (Steindachner, 1893) individual with a total length of 140 mm and a total weight of 58.4 g was caught by trap at a depth of 14 meters, with a mixed bottom of sand and stones, in front of the beach of Banias (N: 35) ° 7. 0.5' 17', E: 35° 54' 14.73). In this work, we document the first record of a Red Sea species (Lesbesian immigrant), Heniochus intermedius (Steindachner, 1893), in the Syrian coast, the seventh record in the entire Mediterranean. As a result, the number of fish migrating from the Red Sea to the Syrian marine waters has reached 82 species. The methods of introduction and arrival of fish of this species into the Mediterranean are also discussed.
