Fish-urchin - Porcupinefishes (Diodontidae) Dlinnoshipaya fish hedgehog Spot-fin porcupinefish Diodon hystrix their short terete body can swell up like a blowfish. Jaw teeth fused into beak plates without cross seam, so the upper and lower jaws is one tooth (diodon in Latin means "bidentate"). The scales on the body transformed into thorns, sometimes quite long, which in the quiescent state close to the body, while inflating the fish are raised vertically. Small dorsal and anal fins lack spines, and shifted to the tail.Pelvic fins are absent. The majority of these fish are mid-sized, but some species can reach one meter in length.
Dvulineyny Cardinal. Two-lined cardinalfish Archamia bilineata (Apogonidae)
Titan triggerfish, Red Sea, Egypt. Titan triggerfish. Balistoides viridescens (Balistidae) up to 75 cm male guards his clutch Titanium triggerfish even dangerous for divers - its massive teeth clearly hints at this.Each jaw carries eight powerful incisors in the upper jaw and they have strengthened the second row of six dental plates. If we consider that the dental apparatus is driven by powerful muscles of the lower jaw, it becomes clear why triggerfish easy to crack the thick shells of mollusks, coral branches and crushed shells of sea urchins and crabs. One of the favorite food items triggerfish - sea urchins. If triggerfish senses danger, it hides in coral crevice where spreads dorsal thorn latch and abdominal spike, so pull it becomes completely impossible. Normally triggerfish swim by undulating movements of dorsal and anal fins.
Dusky stegastes. Dusky farmerfish Stegastes nigricans (Pomacentridae)

Nudibranchs. They are reminiscent of garden slugs, but are whimsical and brightly colored growths.Almost all of them, if not beautiful, it is elegant. Unlike other mollusks have no shell, but that does not mean that animals are vulnerable to enemies: their body is covered with unpleasant mucus and the skin contains numerous glands secreting poisonous substances, scaring predators. Bright and extravagant coloring as if warns of the presence of such a chemical protection. The economic activity of man, these animals do not play any role, but the meeting with them under water brings aesthetic pleasure. Spanish dancer Spanish dancer Hexabranchus sanguineus (Rüppell & Leuckart, 1828) (Hexabranchidae) The largest nudibranch, reaching half-meter length. His name was of a bright red color with a white body. It feeds on a variety of sponges, from whom receives a poisonous substance, making it inedible to predators.

Actiniaria) - detachment from the class of marine Cnidaria coral polyps (Anthozoa). Representatives deprived mineral skeleton. Clown fish, or amfipriony (lat. Amphiprion) - genus of marine fishes of the family pomacentridae. Little Indo-Pacific fish genus Amphiprion (clown fish) live among the tentacles of large sea anemones, entering the latest in a symbiotic relationship. Anemones "recruit" young fish, highlighting attract their agents (attractants). The attractants are species-specific, ie only attract a certain type of organisms. Covering fish mucus does not contain substances that trigger Popping nematocysts so they can exist between the tentacles of sea anemones in the deadly habitat for other animals. Sea anemone fishes provides protection and food debris and fish are attracted to the "owner" prey (fish of other species), protect it from certain predators (butterfly fish), remove necrotic tissue and swimming among the tentacles, "aired" actin, preventing silt contamination.

It is found in tropical, subtropical and warm temperate waters of all oceans. It lives on the outside, and on the slope of the reef lagoon, as well as among the thickets of vegetation. Despite the large size, well masked. Sometimes it drops to a depth of 120 meters. Keeps alone. View omnivorous - consumes as vegetation and a variety of invertebrates, including gorgonians, colonial anemones and tunicates. Breeding has not been investigated in detail. It is known that the bottom lays eggs and larvae live a long time in the water column. Young fish are often held among floating algae, including Sargassum. There are reports that the meat of this fish caused ciguatera. (Lyricist - Smirnov SA)
