AbstractOn the evenings of June 11 and 12, 2019, 5 and 6 days before full moon, broadcast spawning by four echinoderm species and two mollusc species was observed on the Marsa Shagra reef, Egypt (25° 14′ 44.2" N, 34° 47′ 49.0" E). Water temperature was 28 °C and the invertebrates were observed at 2–8 m depth. The sightings included a single basket star Astroboa nuda (Lyman 1874), 2 large Tectus dentatus (Forskal 1775) sea snails, 14 individuals of the Leiaster cf. leachi (Gray 1840) sea star and 1 Mithrodia clavigera (Lamarck 1816) sea star, 3 Pearsonothuria graeffei (Semper 1868) sea cucumbers, and 2 giant clams, Tridacna maxima (Röding 1798). The observations presented here provide relevant information on broadcast spawning of non-coral invertebrate taxa in the Red Sea, where spawning is considerably less well documented than in other tropical geographical regions such as the Indo-Pacific and Caribbean.

SummaryIn this work, radiochemical analysis results of 126 unrecrystallized coral samples from the Egyptian shoreline of northwestern Red Sea and 120 fossil mollusk shell samples from the Atlantic coast of Moroccan High Atlas at the North of Agadir City in Morocco are presented and discussed. The coral samples were collected in Egypt from the emerged coral reef terraces over 500 km from The Ras Gharib-Ras Shukeir depression (28°10') in the north to Wadi Lahami (north of Ras Banas, 24°10') in the south. The fossil mollusk shells were collected in Morocco from Agadir-Harbour in the south to Tamri village in the north extending over about 50 km. The statistical distributions of results (For corals,For mollusk shells, except for Holocene sea level,

A new zooxanthellate reef-dwelling scleractinian coral species, Porites fontanesii sp. nov. (Scleractinia, Poritidae), is de-scribed. The examined material was collected from the Southern Red Sea, the Gulf of Tadjoura, and the Gulf of Aden.Porites fontanesii sp. nov. was most frequently observed along the Yemen south Red Sea and the north-western Gulf ofAden coasts. Although a complete molecular phylogeny of Porites is not available yet, the relationships between P. fon-tanesii sp. nov. and twenty other species of the genus were explored through analysis of the available rDNA sequences.Porites fontanesii sp. nov. was seen to be a distinct species basal to, and well divergent from, one of the two main clades so far identified in the genus rDNA phylogeny.
