A survey of copepods from intertidal zone of the Persian Gulf and the Gulf of Oman resulted in discovery of three new species belonging to the family Canuellidae Lang, 1944. This work contributes to the final aim to describe meiobenthic copepods from this region and is the first description of meiobenthic copepods from Iranian coastline. The new species belong to the genera Brianola Monard, 1926, Canuella, T. & A. Scott, 1893, and Scottolana Huys, 2009. Compared to other congeners, Brianola haliensis sp. nov. is unique in the armature of the first leg, number of segments and setation of the antennary endopod and exopod. Canuella persica sp. nov. is easily distinguishable from its congeners by the shape of furcal rami and male genitalia. Scottolana gomezi sp. nov. is assigned to the longipes-group by the presence of two and three post-genital somites in the female and male, respectively. It is closely related to S. geei (Mu & Huys, 2004) recorded from the Bohai Sea, China, but can be distinguished by its eight-segmented antennary exopod, mouthparts setation, and shape of the furcal rami.

We report new findings of live specimens of Nassarius persicus (Martens, 1874) and N. tadjallii Moolenbeek, 2007, extending their range to the Gulf of Kachchh, Gujarat, India. The known distribution of both species was limited: N. persicus was distributed in the Persian Gulf, Gulf of Oman, and Karachi in Pakistan; N. tadjallii was reported from the Persian Gulf and the Gulf of Oman. We also provide comprehensive taxonomic descriptions of both species, along with additional morphological and ecological information.

The material of the present checklist has been collected from the Iranian intertidal and shallow subtidal shores of the Persian Gulf and Gulf of Oman from 2015 to 2019, in addition to re-examining all the materials deposited in the Zoological Museum of the University of Tehran. This checklist providing 16 new records for the Persian Gulf and 15 for the Gulf of Oman raised the number of recorded caridean shrimps to 109 and 49 for these gulfs, respectively. However, the actual number of these shrimps are higher than these numbers due to two facts. Firstly, most of the subtidal diverse ecosystems, e.g. coral reefs and seagrass bed have not been seriously investigated taxonomically. Secondly, there are some members of species complexes and probably some new species in the study which need to be carefully treated.

Abstract. The Persian Gulf Water and Red Sea Water are salty and dense waters recirculating at subsurface in the Gulf of Oman and the Gulf of Aden respectively, under the influence of mesoscale eddies which dominate the surface flow in both semi-enclosed basins. In situ measurements combined with altimetry indicate that the Persian Gulf Water is driven by mesoscale eddies in the form of filaments and submesoscale structures. In this paper, we study the formation and the life cycle of intense submesoscale vortices and their impact on the spread of Persian Gulf Water and Red Sea Water. We use a three-dimensional hydrostatic model with submesoscale-resolving resolution to study the evolution of submesoscale vortices. Our configuration is an idealized version of the Gulf of Oman and Aden: a zonal row of mesoscale vortices interacting with north and south topographic slopes. Intense submesoscale vortices are generated in the simulations along the continental slopes due to two different mechanisms. The first mechanism is due to frictional generation of vorticity in the bottom boundary layer, which detaches from the topography, forms an unstable vorticity filament, and undergoes horizontal shear instability that leads to the formation of submesoscale coherent vortices. The second mechanism is inviscid and implies arrested topographic Rossby waves breaking and forming submesoscale coherent vortices where a mesoscale anticyclone interacts with the topographic slope. Submesoscale vortices subsequently drift away, merge and form larger vortices. They can also pair with opposite signed vortices and travel across the domain. They can weaken or disappear via several mechanisms, in particular fusion into the larger eddies or erosion on the topography. Particle patches are advected and sheared by vortices and are entrained into filaments. Their size first grows as the square root of time, a signature of the merging processes, then it increases linearly with time, corresponding to their ballistic advection by submesoscale eddies. On the contrary, witout intense submesoscale eddies, particles are mainly advected by mesoscale eddies; this implies a weaker dispersion of particles than in the previous case. This shows the important role of submesoscale eddies in spreading Persian Gulf Water and Red Sea Water.

Extensive samplings of benthic fauna along the Iranian coastlines of the Persian Gulf and Gulf of Oman during 2018–2019 resulted in a small series of shrimps of the alpheid genus Salmoneus. Based on a thorough examination of this material, as well as previously collected specimens, one new species, S. rashedi n. sp., is described, whilst a significant range extension of S. chadwickae Ďuriš & Horká, 2016 is reported. Salmoneus rashedi n. sp. is a member of S. gracilipes species group. The present new species differs from other species of the group by a longer rostrum with a short dorsal crest and a single ventral rostral tooth; the species occurs in two colour forms from yellow to reddish orange with some transverse red bands.
