When Japanese scientists in 1995 discovered on the ocean floor near the Islands Amami mysterious circular patterns, has long wondered: who or what is the author of these unusual works of art? Mysterious figures appeared and disappeared in different places, but never the researchers were not able to catch the unknown “artist” for his work. Did not managed until 2011, when for the past 12 months a team of underwater scientists monitored the underwater area, where often there were intricate designs. A talented artist was fish species Prickly aratron. But why she needed such a work of art?
Prickly aratron (Arothron hispidus) is a ray-finned fish of the family Blowfish, live in the Red sea, Indian and Pacific oceans. These fish are solitary and prefer a sandy sea soil in lagoons and on outer reefs at depths from 1 to 50 meters. The thing is that for the survival of caviar these fish need sand to almost perfect consistency. That is why the male builds a special “nest” of sand so that a 25% decrease in the force of the current, and configure everything so that the center of the nest was demolished grit best suited for masonry. Kind of an engineering triumph of a tiny fish. We offer you to see this amazing footage with your own eyes, because their shooting Japanese researchers have spent much effort and time.
For the construction of architectural works in males Prickly arothron takes about a week. They carefully clean the area from various debris, verify the diameter of the socket direction and digging their grooves. Everything must be perfect. The final touch is the fish version of “candy and flowers” to attract females. To do this, the male lays on the edges of the slot beautiful shells and waiting for a passing female will notice them float to the center of the nest and give him to understand that they are ready to spawn. The act of love of the fish looks quite unusual: the male bites the female behind the “cheek”, and in this position they dance for a few seconds. After the eggs are laid and fertilized, the female leaves the nest forever. Now nature will do for fish everything else. A lone male will erect his next architectural masterpiece on the new ground.
