Using ecological, taxonomic and phylogenetic approaches, we here describe geographically isolated symbiotic relationships between a gobiid fish and two misdescribed alpheid snapping shrimps. This was discovered in the southwestern province of the Persian Gulf, more specifically, in the harsh hyperarid intertidal zone separating the coastal ecosystem from the Middle East desert. Phylogenetic results based on the 16S rRNA gene indicate the existence of two new cryptic species within the Alpheus lobidens De Haan, 1849 species complex, described and named here as Alpheus qatari n. sp. and Alpheus arabicus n. sp. Furthermore, phylogeographic results suggest resurrection of Alpheus crassimanus Heller, 1865 within the same species complex. A phylogenetic comparison of the endemic Arabic goby Cryptocentroides arabicus (Gmelin, 1789) with some of its congeners confirms its presence along both sides of the Persian Gulf. Ecologically noteworthy is the facultative symbiotic interaction between this endemic Arabic goby with the two mentioned endemic alpheid shrimps within two distinct ecosystems. Therefore, we herewith report a case of exceptional symbiosis of a littoral fish species with two potential partners, niche-restricted to shallow intertidal zones, however, with niche differentiation defined by the adaptability of each associated shrimp species. Furthermore, the presence of the goby depends on suitable sediment needed for burrowing: either gravel in the periphery of coral reefs, or mud in the periphery of mangrove ecosystems. The corresponding ecology, taxonomic status and phylogeography are discussed with respect to the recorded facultative character of the symbiotic relationship.

AbstractThree new species of snapping shrimps of the genusAlpheusare described from the Persian Gulf. These belong to theAlpheus edwardsiispecies-group, which is mainly characterized by unarmed orbital hoods and the presence of dorsal and ventral notches on the palm of the major chela.Alphus ankerisp. nov. shows a close affinity toA. pacificusDana, 1852 andA. heronicusBanner & Banner, 1982 bearing no balaeniceps crests in both sexes on the dactylus of the minor chela, and the merus of the major chela of both sexes are unarmed. This species differs from the closely related species by the absence of an overhanging proximal shoulder in the major chela. The other rock crevice inhabiting species,A. mohammadpourisp. nov. is diagnosed by exhibiting sexual dimorphism in its balaeniceps crests and the armed merus of the major chela. These two characters are similar to those recorded for three sandy/rubble dwelling species:A. inopinatusHolthuis & Gottlieb, 1958,A. lobidensDe Haan, 1849 andA. australiensisBanner & Banner, 1982. This new species is distinguishable from these latter species by the shape of the minor chela and colour pattern. A coral inhabiting speciesA. abumusasp. nov. appears to be closely related toA. maindroniCoutière, 1898, showing an armed merus of the major chela and the absence of spine-like seta on the ischia of the third legs. This last new species is easily discriminated fromA. maindroniby longer antennular segments, a markedly concave frontal margin between the rostrum and orbital hood, and a different colour pattern.

Boleophthalmus Dussumieri

Abstract Background Mudskipper is from the Gobiidae family and from the subfamily Oxudercinae. Mudskipper contains four main genera Boleophthalmus, Periophthalmodon, Periophthalmus, and Scartelaos. The aim of this research identification of bacterial agent (Marine bacteria) mudskippers Boleophthalmus dussumieri on the Shores of the northern intertidal areas of the Persian Gulf (Abadan, Hendijan and Bahrekan), Iran. The mud sediment and water samples (at the depth of one m), and mudskipper fish samples (near shore at the intertidal) were collected from Abadan, Hendijan and Bahrekan in northern coasts of the Persian Gulf, Iran. Results A total of 80 aerobic bacteria marine (from the intestines of mudskipper, seawater, and muddy sediments ) was identified by biochemical tests and 16S rRNA gene sequence analysis. The bacteria's (Marine bacteria) [Eubacterium] tenue strain DSM 20695, Praclostridium bifermentans strain JCM 1386 and Vibrio hyugaensis strain 090810a was first identified in the northern intertidal areas of Persian Gulf, Iran. Conclusions Bacteria compete with other organisms to get oxygen to the surface layers of the flower bed. They give that the bacterial species common to the fish intestines and sediments is high and due to fish feeding of sediment it can be concluded that the species present in the fish intestine in the present study may be a function of substrate species that needs further studies to prove this.

The Relationship

The relationship between morphometric characters (length, weight and height) of otolith and fish standard length was determined for six intertidal gobiid species from the northern Persian Gulf and Oman Sea. A total of 144 sagittal otoliths were extracted and anlysed from Periophthalmus waltoni, Boleophthalmus dussumieri, Scartelaos tenuis, Istigobius ornatus, Bathygobius meggitti and Trypauchen vagina. Regression equations were derived and found that there is no significant difference in regression coefficients between left and right otoliths of the species studied. Results of the study showed that otolith length (OL) and height (OH) could estimate standard length in all the species studied except in T. vagina, where the otolith weight gave the best estimate of standard length. Results clearly indicated that otolith dimensions of the gobiid fishes studied could provide information about the species and size.

A New Species

Published records on the Ophiuroidea fauna of the Persian Gulf and Gulf of Oman are scattered in difficult to access journals and books. This study presents a compilation of all published records, complemented with data from new samples. Distribution, habitat and depth in the study area, as well as known Indian Ocean distributions, are included. The taxonomic status of all species was evaluated, critical comments were added as applicable, and several previous records were reassigned to other species. Ophiocoma erinaceus was removed from the fauna of the Persian Gulf and Gulf of Oman, because the only published record was instead Ophiocoma schoenleinii. Previous studies assumed that 46 species of brittle star were known from the study area, but only 38 species were confirmed by this re-assessment, including two new records (Ophiothrix (Ophiothrix) foveolata and Ophiocomella sexradia). Diagnostic features are supplied for difficult to distinguish species. Five species (Macrophiothrix elongata, Amphiura fasciata, Amphiura (Ophiopeltis) hexactis, Amphioplus echinulatus, and Amphioplus seminudus) are so far worldwide known only from the Persian Gulf area. A hexamerous, fissiparous species of Ophiothela that does not concur with any known species was found and may represent a new species. All newly collected species are illustrated with photographs.

Neanthes Glandicincta

Currently, only 31 nereidid species are known from the Persian Gulf and Gulf of Oman. The present study was carried out in order to investigate the poorly known diversity of nereidid polychaetes from seas of the southern coasts of Iran. Specimens were collected from 23 locations along the intertidal zones of the two water bodies. Among the 26 species found: two are new, and are described here, including Simplisetia qeshmensis sp. nov. and Neanthes biparagnatha sp. nov.; 11 are new geographical records. Neanthes biparagnatha sp. nov. is most similar to N. deplanata (Mohammed, 1971), which is also found in the Persian Gulf, but can be most easily distinguished from it by the presence of bars in addition to cones in Area IV of the pharynx. Simplisetia qeshmensis sp. nov. may be distinguished from its closest congener, S. erythraeensis (Fauvel, 1918), also reported from the Persian Gulf, by having a greater number of paragnaths in Area I of the pharynx, an additional type of chaeta (homogomph spinigers) in the ventral neuropodial fascicle and having a reduced notopodial lobe in posterior chaetigers. The list of new records includes: one species from both areas, Neanthes glandicincta (Southern, 1921); eight species from the Persian Gulf, Leonnates decipiens Fauvel, 1929, Neanthes acuminata (Ehlers, 1868), Neanthes sp., Neanthes sp. cf. N. acuminata, Nereis sp. cf. N. pelagica Linnaeus, 1758, Perinereis cultrifera (Grube, 1840) species complex., Pseudonereis trimaculata (Horst, 1924), Pseudonereis sp. cf. P. variegata (Grube, 1857) and two from the Gulf of Oman, Leonnates persicus Wesenberg-Lund, 1949 and Perinereis kuwaitensis Mohammed, 1970. The present study brings to 40 the number of nereidid species currently known from the Persian Gulf and Gulf of Oman. A taxonomic key to nereidid species from the intertidal zones of the Persian Gulf and Gulf of Oman is presented to facilitate future investigations.

Annotated Checklist

In the present study, shrimps belonging to the genus Alpheus from the Persian Gulf and Gulf of Oman are documented based on the existing literature and extensive new sampling from 2013 to 2018 along the Iranian coast. A total of 35 species are recorded from the region, of which 40% (14 species) and 60% (21 species) are new records for the Persian Gulf and Gulf of Oman, respectively. Among 19 sampling localities, A. lobidens De Haan, 1849, A. edwardsii (Audouin, 1826) and A. edamensis De Man, 1888 occurred in 14, 13 and 9 localities, respectively. Among the visited habitats, 14 species (40%) were associated with coral or other sessile invertebrates, 13 species (37%) were collected on sandy or rocky substrates, five species (14%) were obtained from muddy substrates, and three species (9%) were found associated with goby fishes. Among Alpheus species, three (10%) were endemic to the Persian Gulf. Most taxa show affinities to both western Indian Ocean and East Indian/West Pacific Oceans.

Partial Revision

The pontoniine shrimp Philarius gerlachei (Nobili, 1905) is revised based on Nobili’s type material from the Persian Gulf and specimens recently collected in Madagascar, Australia and French Polynesia. Philarius gerlachei is redescribed and four species are described as new: P. polynesicus n. sp. from Moorea, French Polynesia; P. rufus n. sp. and P. minor n. sp., both from Heron Island, Great Barrier Reef, Australia, and P. albimaculatus n. sp. from Nosy-Bé, Madagascar. These species differ from P. gerlachei and/or from each other by a combination of morphological characters and species-diagnostic colour patterns. All species of Philarius appear to be obligate associates of branching corals of the genus Acropora.
