Striped eel cat fish ( Plotosus lineatus ) .. Reach up to 32 cm. at depth 1 - 30 m .. Most of world`s 2000 Cat Fish species occur in fresh water . Only two families contain marine species . It is found in inshore habitats including estuaries and tide pools . Juveniles occur in dense schools over sand and sea grass , adults live solitarily and hide by day . At night they prey on crustaceans , molluscs and fish ..
One should avoid handling these Cat Fish , as their stout pectoral and dorsal fin spines are highly venomous and have strong barbs on their edges that make removal from a wound difficult ..
Stings are extremely painful and can be fatal . Heat ( water or air from hair dryer , as hot as the stung person can tolerate ) has to be applied to the wound as soon as possible to destroy the toxic proteins ..

Arabian angel fish ( Pomacanthus maculosus ) .. Reach up to 50 cm. at depth 2 - 60 m. The species is often seen solitary and inhabits fringing reefs with rich coral growth , but also muddy areas . It was observed leaving the coral reef to feed in nearby beds of sea grass as well . Due to its distribution from the northern tip of Aqaba Gulf to the western tip of the Arabian Gulf this species deserves its popular name Arabian Angel Fish .

Good evening my dear friends .. I wish you all a happy new year ..
The remoras sometimes called suckerfish are a family ( Echeneidae ) of ray-finned fish in the order Perciformes . They grow to 7–75 cm long . Their distinctive first dorsal fins take the form of a modified oval, sucker-like organ with slat-like structures that open and close to create suction and take a firm hold against the skin of larger marine animals . The disk is made up of stout , flexible membranes that can be raised and lowered to generate suction . By sliding backward , the remora can increase the suction , or it can release itself by swimming forward . Remoras sometimes attach to small boats , and have been observed attaching to divers as well . They swim well on their own , with a sinuous , or curved , motion . Remora front dorsal fins have evolved to enable them to adhere by suction to smooth surfaces and they spend their lives clinging to a host animal such as a whale , turtle , shark or ray . It is probably a mutualistic arrangement as the remora can move around on the host , removing ectoparasites and loose flakes of skin , while benefiting from the protection provided by the host and the constant flow of water across its gills . Although it was initially believed that remoras fed off particulate matter from the host's meals , this has been shown to be false , in reality , their diets are composed primarily of host feces . Remoras are tropical open-ocean dwellers , but are occasionally found in temperate or coastal waters if they have attached to large fish that have wandered into these areas . In the mid-Atlantic Ocean , spawning usually takes place in June and July , in the Mediterranean Sea , it occurs in August and September . The sucking disc begins to show when the young fish are about 1 cm long . When the remora reaches about 3 cm , the disc is fully formed and the remora can then attach to other animals . The remora's lower jaw projects beyond the upper , and the animal lacks

Potato grouper ( Epinephelus tukula ) .. Reach up to 200 cm. at depth 3—80 meters . The potato grouper is one of the largest bass in the world that lives in the coral reef . It is easily identified by its light-colored body with black spots . It derives its name from its spots, which resemble the eyes of a potato . It aggressively defends its territory against other fish . Considered to be exceedingly territorial and very aggressive towards intruders . Feeds on reef fishes , skates , crabs , and spiny lobsters .. The islands dive site ..

Good evening my dear friends ..
Snowflake moray ( Echidna nebulosa ) .. Reach up to 60 cm. at depth 1—40 m. Found singly on inshore protected reef flats , hiding in dead coral . They feed on fish and invertebrates . Morays open and close their mouths to move water through their gills for respiration . This behavior can often be seen as a threat especially towards divers , in fact this is far from the truth , they are very shy creatures and will only attack if provoked .

Good evening my dear friends ..
Hawksbill sea turtle ( Eretmochelys imbricata ) .. They are primarily found in tropical coral reefs . They are usually seen resting in caves and ledges in and around these reefs throughout the day . As a highly migratory species , they inhabit a wide range of habitats , from the open ocean to lagoons and even mangrove swamps in estuaries . While the hawksbill sea turtles mainly feed on sponges found on coral reefs , they also feed on crustaceans , algae and fish . They are prey to large fish , sharks , and humans . The hawksbill sea turtles are unfortunately endangered mainly due to human impact . These sea turtles mainly stay close to shorelines as this is where sponge-bearing coral reefs can be found , as well as beaches that provide nesting sites . Not much is known about the life history of hawksbills . Their life history can be divided into three phases , namely the Pelagic phase , from hatching to about 20 cm , the Benthic phase , when the immature turtles recruit to foraging areas , and the Reproductive phase , when they reach sexual maturity . The Pelagic phase possibly lasts until the turtles reach around 20 cm in length in 1–3 years , reaching sexual maturity at around 40 cm (2–4 years) . Hawksbills show a degree of fidelity after recruiting to the Benthic phase , however movement to other similar habitats is possible . Adult hawksbill sea turtles typically grow to 1 m in length , weighing around 80 kg on average . The heaviest hawksbill ever captured weighed 127 kg .

Sergeant major ( Abudefduf vaigensis ) .. Adults can grow up to 23 cm. at maximum length . Normally , they would grow up to 15 cm. The largest recorded specimen weighed had a weight of up to 200 gr. This fish is white with a yellow top . It has 5 vertical stripes which are black . A faint sixth stripe might be present on the caudal peduncle . Adult males have a more bluish coloration and its stripes are less visible . There is a dark spot around its pectoral fin . This fish feed upon the larvae of invertebrates , zooplankton , smaller fish , crustaceans , and various species of algae . Individuals of this species form aggregations of about several hundreds of individuals . Sometimes , they get cleaned of parasites by fish species such as gobies in the genus . Sergeant majors also clean green sea turtles ..

Devil scorpion fish ( Scorpaenopsis diabola ) .. Reach up to 22 cm. At depth 5 - 70 m. A relatively uncommon inhabitant of rubble or weedy coralline-rock bottoms , reef flats , lagoons and seaward reefs . This exceedingly ugly creature has a colorful surprise for those who disturb it . It flashes the underside of its pectoral fins that are brilliantly colored in yellow , orange and black . Presumably this is an effective warning ..

Good evening my dear friends.. Dolphin (disambiguation) .. Dolphins are a widely distributed and diverse group of aquatic mammals . They have streamlined bodies and two limbs that are modified into flippers . Though not quite as flexible as seals , some dolphins can travel at 55.5 km/h . Dolphins use their conical shaped teeth to capture fast moving prey. They have well-developed hearing which is adapted for both air and water and is so well developed that some can survive even if they are blind . Some species are well adapted for diving to great depths. They have a layer of fat, or blubber, under the skin to keep warm in the cold water . Dolphins feed largely on fish and squid , but a few , like the killer whale, feed on large mammals , like seals. Male dolphins typically mate with multiple females every year , but females only mate every two to three years . Calves are typically born in the spring and summer months and females bear all the responsibility for raising them. Mothers of some species fast and nurse their young for a relatively long period of time . Dolphins produce a variety of vocalizations , usually in the form of clicks and whistles .
