    Description: The sohal surgeonfish or sohal tang, Acanthurus sohal, is a Red Sea endemic which grows to 16 in (40 cm) in the wild. Its striking blue and white horizontal stripes have made it what many consider the 'poster fish' for the Red Sea reef environment. It is a valued aquarium fish. A common species found in seaward edges of reefs exposed to surge. Aggressive and territorial. Feeds on various kinds of algae, mainly Sargassum, and fine filamentous green algae. Caught with nets; traps and occasionally by trawls.

    Description: This is one of the largest species of angelfish reaching almost 20 inches (50cm) in length. As an adult it has a violet blue body with a large yellow blotch on the side that some say resembles the continent of Africa. As a juvenile it is similar in appearance (and easily confused with) other young Pomacanthus, especially the Blue-ring Angelfish P. annularis. But as its color pattern begins to metamorphosis, the sub-adult begins to look very much like the Arabian Angelfish P. asfur. It will have a similar looking vertical yellow bar on its body, but lack the bright yellow tailfin of the Arabian Angel. Its yellow marking develops as a characteristic "yellowband", finally becoming more prominent and blotch-like as the fish ages. Hence this fish is also known by a number of descriptive common names including Yellowbar Angelfish, Half Moon Angelfish, Map Angelfish, Yellow-Band Angelfish, Yellow-blotch Angelfish, Blue-moon Angelfish, and more.

    Description: Chrysiptera unimaculata, an algivorous species also living on the coral reef flat and being territorial but not considered as a strict farmer in this location. Maximum length is 8 cm in Persian Gulf. It is living in close association with macrophytes. Adults are found solitarily or in small groups among coastal algal reefs, rubble or over open beach-rock of reef flats exposed to moderate surge and feeds mainly on benthic algae. C. unimaculata is oviparous, distinct pairing during breeding. Eggs are demersal and adhere to the substrate. Males guard and aerate the eggs.

    Torpedo sinuspersici  Olfers, 1831 (2021)

    Description: Electric rays, thought to be the most primitive of the skates and rays, have stout tails but have rather expansive disc. This group is distinguished by the presence of powerful electric organs, derived from branchial muscles in head region. Torpedo sinuspersici found inshore in sandy bottoms, and well offshore from the surf zone down to 200 m. Also on or near coral reefs (like Kish Island in Persian Gulf). Common in shallow sandy areas. Occasionally hooked by anglers, more often seen by divers; can deliver a strong shock. Flesh is edible. T. sinuspersici can survive for hours after being stranded on the beach. Little is known of the life history of the Gulf torpedo. It is a sluggish predator of bony fishes. At night it actively hunts for food, sculling slowly through the water about a meter above the bottom; during the day it usually rests on the bottom and opportunistically ambushes unwary prey. It uses its broad pectoral fins to envelop the target fish before delivering an electric shock to stun it. Usually solitary, they may form groups during the mating season. Reproduction is a placental viviparous, with the developing embryos initially surviving on their yolk sacs, and then on enriched uterine fluid produced by the mother. Litters of 9-22 young are birthed in the summer. Newborns measure about 10 cm wide; males mature at a disc width of 39 cm and females at 45 cm.

    Boloceroides spp. (2021)

    Description: Boloceroides spp. are looking like an untidy mop, this anemone is sometimes seen in sea grass areas on many of our shores. It is possibly seasonal. Sometimes, large numbers are seen (up to 10-20 animals in a trip) and then none at all.  Tiny swimming anemones may sometimes be confused with Sea grass anemones which have translucent tentacles with tiny spots. The swimming anemone harbors symbiotic single-celled algae (zooxanthellae). The algae undergo photosynthesis to produce food from sunlight. The food produced is shared with the sea anemone, which in return provides the algae with shelter and minerals. The oral disk and tentacle muscles are used to obtain, retain, and ingest prey; in Boloceroides spp. tentacles can autotomize if it is needed to evade a predator. Tentacles can control body form by use of their endodermal muscles. Retractors are longitudinal muscles that will aid in withdrawing tentacles and the oral disk if they are exposed to the open air.  This hypothesis is furthered because in comparison to other sea anemones, Boloceroides is loosely attached to its respective substrate, thus allowing the pedal disk to detach quickly resulting in a rapid swimming response. Boloceroides can reproduce both sexually and asexually. As Anthozoans, Boloceroides produce sexually by bypassing the medusa life cycle stage; this allows Boloceroides (and all Anthozoans) to release their egg and sperm creating planula a bilaterally symmetrical, flattened, ciliated, motile larva.

    Description: Many aquarists know this fish as Ambylgobius hectori but accepted name is actually Koumansetta hectori. K. hectori, Hector's goby, is a species of goby native to the Indian Ocean (including the Red Sea), first record from Persian Gulf (Kish Island, Iran) to the islands of Micronesia in the western Pacific Ocean. It can be found on sheltered coral reefs at depths of from 3 to 30 meters (though usually between 5 to 20 meters). This species reaches a length of 8.5 centimeters (3.3 in) SL. This attractive little fish measures only 2” at maturity and spends its time hovering over rocks and substrates out in the open water column. Known for their bold yellow stripes, peaceful disposition, the diminutive Hector’s Goby is a nano reef favorite. It can also be found in the aquarium trade.

    Description: Pempheris vanicolensis has reported for the first time from Persian Gulf (Kish Island). Various aspects of the biology of P. vanicolensis Cuvier & Valenciennes, a recent Lessepsian (Suez Canal) immigrant into the Mediterranean, are given. Red Sea and Mediterranean populations were compared, and the results indicate that the spawning season is shortened in the Mediterranean, continuing from April to September, as opposed to year-round in the Red Sea. Descriptions of a ripe ovary and post-larva from the Mediterranean are given. Individuals reach a mean size of 10.8 cm in their first year, and 14.4 cm in the second year. Little change has occurred in the diet of the immigrant population, and both populations feed nocturnally, chiefly on larval and adult stages of planktonic crustaceans. Direct underwater observations on the diurnal behavior of the species show that the fish leave their daytime cave shelter at sunset, congregate at a nearby site and then migrate inshore and disperse into small groups to feed. Before dawn, they reassemble at the cave's entrance, and finally enter it at sunrise, after the school has built up. Observations on Persian Gulf sweepers show that the fish are segregated into size groups, ranging 15–18 cm adults at depths of 3 m.

    Description: Chromis viridis (green chromis) is a species of damselfish. It is found in tropical and subtropical waters. C. viridis is encountered in wild specimens prefer to school in large shoals amongst branching corals like Acropora in sheltered areas such as subtidal reef flats and lagoons. We report for the first time from Iranian Waters) Persian Gulf, Kish Island), we found it at depth of 2-8 m, and Maximum length is 7 cm in Kish Island (Iranian Waters). Adults of this species can grow up to 10 cm at maximum length. When they are breeding, males turn more yellowish. The marriages are a pair matter, but they take place grouped. The males chose for the nest, a small dimple dug in the sand, the dead branch of madrepora or simply, one hospitable seaweed. Then they dance, moving up and down, like if they were jumping inside a virtual column of water, for attracting the attention of the females and show the competitors that is their place. Oviparous, distinct pairing during breeding. Eggs are demersal and adhere to the substrate. Males guard and aerate the eggs. Juveniles closely tied to individual coral heads.
