Would you like to enjoy the beauty of undersea world and sandy beaches, unite with nature and try the role of a wild tourist? Welcome to Gamov peninsula area located in the Sea of Japan.
The beauty of the underwater world of Gamov peninsula area is more outstanding than its over-water landscape. Every meter of the depth reveals new associations of sea organisms giving the divers an opportunity to observe peculiarities of their behavior. Those who can't dive can only stay ashore gazing after divers and watch pictures made under the water later.
The Sea of Japan and the area of Gamov Peninsula have a complex underwater relief and perfect aerodynamics. The water is very transparent and rich in pleasant undercurrents and under sea fauna.
It is known that water temperature is a determining factor in diving planning.Its deviations are significant and account for -1+4 in winter, +4+10 in spring,+12+24 in summer and +20+8 in autumn.
Even in August the temperature of water on the surface is +24 and is cold when you dive in. The first layer of transition occurs at the depth of 14-16 meters and temperature drops to +15+12. The second transition layer is observed at the depth of 30-35 meters where the temperature goes down to +7+4. The values are not absolute as from time to time water layers are mixed due to wind and undercurrents and the borders are moving up.
In waters of middle latitudes with considerable seasonal variations in water temperature reef-building corals are not observed and live objects are fixed under water on numerous rocks. Any free surface gets inhabited at once. Places with no braking waves are covered with a layer of actiniae.
A regular actinias reminds of a flower on a thick leg. Itfixes to the rock with its base while the colored part of its body is represented by a mouth surrounded with a number of tentacles. The organisms protect themselves from enemies and feed with the help of the tentacles.Stinging cells on their extremities produce poison if the animal is touched.The tentacles are harmless for a human if he is not going to lick them. Touch the actinias and it will turn into a small prominence.
In spite of the cold corals inhabit the north-western partof the Japan Sea as well. The solitary corals have a skeleton that is feeble though.
Small and rare Scleractinia corals are mostly met in recesses where they are not bothered by waves.
There is a mouth in the center of the polyp and its edgesare covered with tentacles with sizes of 0.5 to 1.5 cm. On irritation the polyphides the tentacles and closes.
In favorable conditions actiniae cover rocks with carpets sothat the rock itself is not visible any longer. The best present for a diver isto get a picture of such gardens.
Waters of the Japan Sea are abundant with echinoderms. These creatures love salty water. Some sea stars are brightly colored and make the composition brighter. In the Far East the spiny-skinned organisms are components of local favorite dishes.
King crabs inhabit both coasts of the northern part of the Pacific ocean. This crab will carry that female till the moult which will be followed by copulation. Its weight ranges from 40 to 60 kg and their length exceeds the human height. The creature constantly examines the world with its tentacles including divers. If you behave in the right way you'll get a chance to play with the octopus.
The giant octopus is busy with making a dwelling under arock.
Seals don't trust anyone especially divers. It's better to stay motionless and then you'll be able to observe what is going on.
The Japan Sea is famous with the sizes of its inhabitants.Foreigners call the area Land of Giants. The jelly fish on the picture is abright example because it is as big as a plate.
Remains of a ship. Its bottom is covered with under sea creatures.
Wreck divers enjoy visiting sunken vessels which are not just pieces of metal but artificial reefs with inhabitants of its own.
If in tropics there is a wide variety of fishes then in the middle latitudes it is the amount of fishes that matters more. In average one can see 10-15 species of fishes at a time. The three-bandedrock-fish is the most brightly colored fish in the Japan Sea. It can be approached in spite of the fact it reacts to water fluctuations immediately.
The Japan Sea is a heaven for divers and those who love nature. Just a couple of lectures in biology devoted to peculiarities of local nature and divers can differentiate between a goggle-eyed fish with tubes and Myoxocephalus brandti which rested next to cucumaria, etc.
It is easy for an experienced photographer to find a hundred of unusual and funny macro objects.
As tiny creatures are vulnerable to carnivores they all adjust in their own way. Some choose special models of behavior, others acquire specific coloring or stay inside the shell all day long.
