ISRAEL JOURNAL OF ZOOLOGY Vol. 16, 1967, pp. 166- 169 LEITER TO THE EDITOR A TENTATIVE LIST OF IMMIGRANTS VIA THE SUEZ CANAL H. STEINITZ Department of Zoology, The Hebrew University of Jerusalem When the Suez Canal was opened in 1869 the waters of the Mediterranean and the Red Sea, which had been separated by the Isthmus of Suez, came into direct contact. For plants and animals, elements of the Atlanta-Mediterranean and the Indo-Pacific-Erythrean flora and fauna, an opportunity was thus created to penetrate into new regions. For one hundred years, the colonisation of the Suez Canal and the movement through this passage has been going on, but surprisingly little is known of its results· The following list*, compiled from numerous sources, is an attempt to show in a preliminary way, what is known today of the outcome of the two-way migration via the Suez Canal. Verification of records has not been made at this stage; rather, records have been adopted at their face value, for the present purpose. A critical evaluation of the data is planned. The amended list, which is to appear at a later date, will be fully documented. FROM RED SEA TO MEDITERRANEAN Plants Algae Cormophyta Cladophoropsis zollingeri (Klitz.) B0 rg. Halophila stipulacea (Forssk.) Asch. Animals Spongia Hydro idea Halichondria viridis (Keller) Pennaria disticha australis Bale Didiscus placospongoides Dendy Filellum serratum (Clarke) • The list was, except for a few changes, part of a paper submitted to the 20th Plenary Meeting of the International Commission for the Scientific Exploration of the Mediterranean Sea (I.C.S.E.M.S.) in Bucharest, October 1966. However, in the actual publication of that paper (Remarks on the Suez Canal as pathway and as habitat. Rapp. Comm. int. Mer Medit., 1968), the list itself could not be included.
