The underwater world of the Andaman sea at Similan Islands

About the trip to the Similan Islands I told separately, record Snorkeling tour to the Similan Islands, only here photos and videos of underwater animals. Filmed at the underwater citramalic Nikon AW100, because the quality is not so hot. Water even at shallow depth greatly distorts colors and good photo underwater can be removed only with external lighting. The footage had to correct in the editor, and everywhere it is managed well. In addition, the conditions with moving water and a small amount of light is very complicate shooting. As could, tried to determine the types of fish encountered. But it’s not all animals that have even seen, not to mention the one who lives in this reserve. From outside the frame there rays, sharks, sea turtles and many others.

From the outside it looked like this: here and there sticking out of the back and the breathing tube

 

The underwater world of the Andaman sea at Similan Islands

Someone like our guide Kate with wide experience in diving, dive deeper, someone was holding at the surface, or explored the coastal rocks.

And at the bottom in the water column is full of life! Which only colored tropical fish there! Float on one and groups. I suddenly turn when I saw a flock of black fish in the video below, I thought that someone here feeds and I was getting just at this place. But no, that is exactly what they pack to move, gnawing rocks and corals, and with them constantly hovering fish of other species. Here you can see the striped pajama surgeon and the parrot fish, which I will discuss below.

Tropical sea is a riot of colors, and not always the camera can capture at least a fraction of the bright colors of marine life. This family of corals among stones from afar a bright azure blue flowers, but the photo turned out something ugly.

But among tropical fish there are a huge variety not only of colors but also shapes. Are very unusual. In the next photo on the right, and in the video below chews a little something on the rocks butterfly fish Kinopalace (aka butterfly fish Auriga, nitara, Latin Chaetodon auriga). She has a black stripe on the face, forming a mask, a converging wedge gray bars on the sides, and a bright yellow tail with black spot on top fin.

Butterfly napera, Kinoproba (Chaetodon auriga) is a small marine fish with an elongated body, extra-long tweezer-like jaws and a very beautiful color. Coloring chaetodon auriga can vary within wide limits and depends on the territory where the fish live. The body is painted mostly in white color with diagonal stripes of black color directed to the dorsal and anal fin. The back of the body and fins yellow. The head is white with a wide black stripe through the eye. The rear part of the dorsal fin has a black edging and a large dark spot, which, depending on the habitat the fish can be less contrasting, if not absent. The size of the fish in natural conditions is up to 23 cm.

Fish is very interesting, inhabits thickly overgrown with corals and lagoon protected from waves by a reef plateau. It is usually in pairs, at a depth of 15 meters. Feeds on anemones, polychaete worms and coral polyps.

Horny zankl / Zanclus cornutus

Horny zankl, or Moorish idol (eng. Moorish idol), lat. Zanclus cornutus is a species of ray-finned fish, the only one in the family Sankovich (Zanclidae) of order Perciformes. The name comes from the Greek word zagkios — bevel. Quite a long time to determine because of the General similarities with apparent fish-butterflies. Like clearly falls in appearance to their family, and on small signs, there are no such! The result was that belongs to a unique family consisting of a single species.

Horny zankl — sea fish length 22 cm high Body discoid, laterally flattened. Body height can range from 1 to 1.4 length. Dorsal fin triangular in shape, it is 6-7 (usually 7) 39-43 spines and soft rays, third spines much elongated, filiform. Some sources indicate that the length of the outgrowth on the dorsal fin can exceed the length of the fish’s body. In a triangular anal fin 3 31-37 spiny and soft rays in the pectoral fins 1 barbed and 17-18 soft rays in the ventral fin 1 spiny and 5 soft rays. Form unpaired fins attached to the body of the fish a characteristic half-moon shape. Scales very small, each scale has a number of vertical ridges, the rear edge of which is scalloped. This gives the surface of the fish body rough, like fine-grained sandpaper. The eyes are set high above them in the adult are the appendages. The snout is elongated, trubkovidnye, with a small mouth at the end; teeth numerous, single-row, setinkane, slightly recurved.

Body color — alternating vertical black and white stripes (disruptive painting), on the snout top has a yellow saddle spot, the tip of maxilla black, mandible mostly black. Villacoublay the caudal fin is black with a light posterior margin. Appearance zankl reminiscent of some of the apparent types of butterfly fish. However, these fish are not linked by kinship, belong to different families and suborders of Perciformes fish (an example of the phenomenon of convergence).

Horny zankl inhabits lagoon with the tides, rocky and coral reefs, preferring areas with hard bottom. Often fish are found in pairs, small groups from 2 up to 3 individuals, or rarely in packs (it’s more typical for young individuals). Sometimes adults form harems of 5-10 individuals. Shankly feed on sponges, bryozoans, coral polyps, other invertebrates and algae. The sponge can be up to 86% of the stomach contents of the studied specimens and are found in all the examined fish. The narrow elongated snout, and the recurved teeth help the fish to pull invertebrates out of the cracks of the reef. Pair formed for life, the male is slimmer and brighter than females, also it is larger outgrowths over the eyes. The male shows aggression to other males of their own species.

It inhabits the plateau and outer slopes of coral reefs. Rests in shallow areas up to 15 meters in pairs or small groups. Young often found in estuaries of rivers. In nature it feeds almost exclusively on coral polyps and tube worms.

Ruby ash scar / Scarus rubroviolaceus

One of the types of parrot fish, parrot fish red-purple, aka ruby the ashen scar, rusty parrot, lat. Scarus rubroviolaceus, eng. Ember parrotfish. The name does not bother you, this species is very different coloration of males and females. The name was given by the female, represented in the photo the male is not red-violet, and green.

These parrot fish are named because of their vivid and variegated colouring and the teeth of a special shape, like a beak. They have the jaws, teeth merge, forming a kind of “parrot’s beak”, which consists of two separated by a seam plates on each jaw. To this family belongs 10 genera and about 80 species. The variety of colors is amazing! And the color varies with age and gender. The fry are usually single color and have stripes, spots or specks on the body. From immature individuals dominated by brown, red and purple tones, but the adults have blue, green, orange, red and yellow, with large males, which often develops gorbalenya growth on the forehead, usually painted in blue-green color.

Live on the reefs. Only a few species extend beyond the propagation of corals, inhabiting in this case (for example, off the coast of southern Japan) on the rocky coasts. Feed on algae and corals, but they also feed on mollusks and other benthic animals. Their strong and sharp teeth bite off a piece of coral, recycles organic matter, and inorganic matter through the digestive tract throw away the fine sand. These fish are solitary lifestyle and is always kept at “their” stations. Some of them have permanent refuge in underwater caves where they spend the night and where hiding in danger. Night many parrotfish secrete a large amount of mucus around itself and form a gelatinous sheath. To create the cocoon, some types require at least 30 minutes, and about the same time leaving in the morning for the release of “bed”. The cocoon serves as protection from parasites (in particular, blood-sucking isopods of the genus Gnathia, as well as hides its scent from predators. The cocoon can also perform other functions — for example, helps to maintain the balance of electrolytes.

Zolotovitsky Emperor / Gnathodentex aureolineatus

A gaggle of the many striped fishes, each with a bright yellow spot at the base of the tail. It Gnathodentex aureolineatus, Zolotovitsky the Emperor, eng. Striped large-eye bream from the family latrine.

Zolotovitsky the Emperor — fish of medium size, growing to a maximum length of 30 cm, however, the most frequently observed length is 20 cm Have a laterally flattened body, short snout and forked tail. In the color is dominated by silvery-grey background with Golden lines on the sides and extend to upper side of the body in a darker color. The fins of the Emperor have a pinkish tint, and upper lip has a yellow stripe, resembling a mustache.

Zolotovitsky the Emperor lives at depths to 30 m, active mostly at night, and during the day it can be observed singly or huddled in small flocks near the reef. At night they disperse to feed. The main part of its diet is small prey, for example, benthic invertebrates, various species of crustaceans, gastropod molluscs, and sometimes small fish.

Keep these fish, usually in small groups, meeting in the daytime in different areas of the reef, including channels in the barrier reefs with strong currents and in the coastal zone depth of 1 m, which is surprising for such a large fish. Feed the large plants, including the Sargasso seaweed. Quite omnivorous menu of nosey includes crustaceans, molluscs, worms and other animal food. On the fish-unicorns parasitic microorganism which is poisonous if taken fish meat in the food. Famous cases of poisoning by eating. Multiply in pairs. Juveniles kept in quiet bays and lagoons.

Striped surgeon / Acanthurus lineatus

Fish frames which had accumulated the most. You could see it in previous photos and videos. And no wonder, it is a large marked fish with a bright striped coloring.

Surgeon striped, pajama surgeon, surgeon-clown (lat. Acanthurus lineatus) is a large surgeon fish, striped with contrasting color. As with all fish-surgeons, the body striped surgeon also flattened laterally. The sides of the body brightly painted in blue and yellow stripes, belly is clear blue, the dorsal fin is yellow. Anal and pelvic fins orange. Body length 38 cm. the Tail is lyrate.

A distinctive feature of the fish-surgeons are the sharp spikes at the top and bottom of the caudal fin. For such a sharp tail of the fish is sometimes called “fish-scalpels”. These are dangerous as the razor-sharp spikes, the animal uses as a weapon of self-defense, so sometimes come the news received divers wounds, once ventured to Pat the surgeon.

In most species well developed instinct to guard his territory. He begins to appear already in the immature age, when the fish does not come close to competitors for “your” food. Also in some species there is a situation where one strong male “in charge of” the territory of several females located nearby.

In the absence of sufficient quantities of food, or in competition, fish-surgeons can gather in large swarms for cooperative feeding. Such forays for food can collect up to several thousand fish, and after feeding the fish again go to their quiet places. For a long time flocks are collected only during the breeding season.

Striped surgeon is held usually near the outer slopes of coral reefs at shallow depths down to 15 meters. Lives singly or in small harem groups. Usually the male guards the territory, which feed several females. Juveniles are found singly in shallow rocky areas. Feeds mainly on algae, but also eat small crustaceans, worms, and other invertebrates.

If, however, surgeon fish used their weapons, it is necessary to treat the surface of the wound using very hot water. Only she is able in a short time to destroy the poison in the poisoned thorns of the fish. Mandatory treatment and disinfection damaged surfaces should be carried out only once will drain the blood and toxins will be washed. Otherwise the healing will be long and painful, it is better to consult a doctor. Fans of scuba diving you must remember that even a minor laceration caused by the fish-the surgeon is able to cause severe pain for more than one hour. Another curious feature of the fish-surgeons is that they can lie on the side and hold in this position for quite a long time.

  1. Here you can see the striped pajama surgeon and the parrot fish, which I will discuss below.

  2. I’m not sure about this post. Your initial thoughts are well made, but unfortunately it’s foolish to count on what strangers may do. Please write more about this, because I find you to be a very eloquent writer and I hope to read more from you!
