Twelve species from the Bay of Bengal, the Red Sea, the western Indian Ocean, and southwestern Australia are reclassified in Marmorofusus. These include: Murex undulatus Gmelin, 1791, a senior synonym of Murex variegatus Perry, 1811 and Fusus laticostatus Deshayes, 1831, formerly regarded as a junior synonym of Marmorofusus nicobaricus (Röding, 1798); Murex verrucosus Gmelin, 1791 (synonyms Fusus tuberculatus Anton, 1839 non Lamarck, 1822, F. marmoratus Philippi, 1846 and F. rudicostatus G.B. Sowerby II, 1880); F. polygonoides Lamarck, 1822 (synonym F. biangulatus Deshayes, 1833); F. tuberculatus (Lamarck, 1822) (synonyms Fusus indicus Anton, 1839, F. maculiferus Tapparone Canefri, 1875, Fusinus t. priscai Bozzetti, 2013 and F. t. fuscobandatus Bozzetti, 2017); Fusus philippii Jonas in Philippi, 1846, an earlier name for Fusus tessellatus G.B. Sowerby II, 1880 (other probable synonyms Fusus exilis Menke, 1843, non Conrad, 1832 and Fusinus dampieri Finlay, 1930, replacement name for F. exilis Menke); Fusus oblitus (Reeve, 1847) (synonym Fusus turrispictus Hedley, 1918); F. leptorhynchus Tapparone Canefri, 1875 (synonym F. subquadratus G.B. Sowerby II, 1880), Fusinus vercoi Snyder, 2004; F. wellsi Snyder, 2004; F. brianoi Bozzetti, 2006; F. verbinneni Snyder, 2006; and F. bishopi Petuch & Berschauer, 2017. Fusus toreuma Deshayes, 1843, sometimes misidentified as M. tuberculatus, is a member of the Fusinus colus (Linnaeus, 1758) species group.

The Relationship

This chapter reviews the evidence, nature, and development of maritime contacts in the Red Sea and from the Red Sea into the western Indian Ocean from the Neolithic until the start of the Islamic period, c. 4000 BCE–700 CE. In addition to summarizing and highlighting recent archaeological research and ongoing scholarly debates, emphasis is placed on identifying and explaining periods of intensified as well as reduced interaction, and on the relationship between internal Red Sea dynamics and contacts with the Mediterranean and the Indian Ocean worlds in light of climate, natural environment, hinterland interest, and a changing geopolitical situation.

Colour Patterns

The Doublebar Seabream, Acanthopagrus bifasciatus (Forsskål 1775) with two conspicuous vertical black bars across the head has long been recognized as a distinctive species from the Red Sea and Western Indian Ocean. Two distinct colour patterns are associated with two allopatric populations except southern Oman and Somalia which appears to be a zone of overlap: a northern population (Red Sea, through Persian Gulf, to Pakistan) with dorsal and caudal fins immaculate yellow; and a southern population (east coast of Africa from the Horn of Africa to South Africa, Madagascar, and Mascarene Islands) having the dorsal fin with a wide black margin and caudal fin rear margin with a narrow black edge (and both black margins disappearing with growth in specimens over 30 cm SL). Both populations resulted in the two valid species: A. bifasciatus for the northern population and A. catenula (Lacepède 1801) for the southern population. Nominal species (junior synonyms) of the two species are discussed.

Population genetic analysis is an important tool for estimating the degree of evolutionary connectivity in marine organisms. Here, we investigate the population structure of the three-spot damselfish Dascyllus trimaculatus in the Red Sea, Arabian Sea and Western Indian Ocean, using 1174 single nucleotide polymorphisms (SNPs). Neutral loci revealed a signature of weak genetic differentiation between the Northwestern (Red Sea and Arabian Sea) and Western Indian Ocean biogeographic provinces. Loci potentially under selection (outlier loci) revealed a similar pattern but with a much stronger signal of genetic structure between regions. The Oman population appears to be genetically distinct from all other populations included in the analysis. While we could not clearly identify the mechanisms driving these patterns (isolation, adaptation or both), the datasets indicate that population-level divergences are largely concordant with biogeographic boundaries based on species composition. Our data can be used along with genetic connectivity of other species to identify the common genetic breaks that need to be considered for the conservation of biodiversity and evolutionary processes in the poorly studied Western Indian Ocean region.

Reservoir Age

Known-age corals from the Cocos (Keeling) Islands, Indian Ocean, have been analyzed by accelerator mass spectrometry (AMS) for radiocarbon to determine marine reservoir age corrections. The ΔR value for the Cocos (Keeling) Islands is 66 ± 12 yr based on the analyses undertaken for this study. When our AMS and previously published dates for Cocos are averaged, they yield a ΔR of 64 ± 15 yr. This is a significant revision of an earlier estimate of the ΔR value for the Cocos (Keeling) Islands of 186 ± 66 yr (Toggweiler et al. 1991). The (revised) lower ΔR for the Cocos (Keeling) Islands is consistent with GEOSECS 14C data for the Indian Ocean, and previously published bomb 14C data for the Red Sea, Gulf of Aden, and Cocos Islands. The revised ΔR is also close to values for the eastern Indian Ocean and adjacent seas. These suggest surface waters that reach the Cocos Islands might be partly derived from the far western Pacific, via the Indonesian throughflow, and might not be influenced by the southeast flow from the Arabian Sea.

Type Specimens

The Red Sea has five species of the apogonid genus Fowleria, including F. isostigma, a Pacific Ocean species not yet known from the western Indian Ocean proper. Previously, F. isostigma was placed in the synonymy of F. punctulata (Rüppell 1838). However, the taxonomic status of the latter has not been established and in previous works it was placed in the synonymy of F. aurita or F. variegata. This paper compares Red Sea specimens identified as F. isostigma with F. variegata and with the type specimens of F. punctulata. The presence of F. isostigma in the Red Sea is established and F. punctulata is confirmed as a junior synonym of F. variegata. The holotype of F. punctulata is identified by the size given in the original description. A key to the Red Sea species of Fowleria is provided.

AbstractThe Mediterranean and Red Sea, which were connected via the Suez Canal during the 19th century after eons of separation, host two distinctive ecosystems. Species invasion through the Suez Canal from the Red Sea vastly influences the ecology of the Mediterranean, but the level of reverse migration is assumed to be negligible. We present the first reconstructed flow transport record through the canal during the period 1923–2016. According to this reconstruction, the flow intensity and direction through the canal are strongly influenced by seasonal and long-term sea-level changes, which could also play a role in the characteristics of species migration through it. Our record not only supports previous observations of the unidirectional invasion until the 1980s and the accelerated species migration rates to the Mediterranean ever since, but also suggest that southward migration could have become possible since the early 1980s. The southward flow was primarily enhanced by Indian Ocean cooling and the Eastern Mediterranean Transition in deep water formation during the period 1980–2000. It was then gradually reduced by accelerated sea-level rise in the northern Indian Ocean.
