eoadies Like tiny, aquatic Marvin Gayes, some species of fish will sing to attract mates. But there is trouble among the underwater crooners: According to a doctoral thesis by marine ecologist Eva-Lotta Blom at Dates in the uk University of Gothenberg in Sweden, two eladies sex of fish called the sand and eladies sex gobies make different "songs" to encourage a female to lay her eggs in his nest.My Wife Loves Sucking Dick
Blom describes the sounds eladies sex the sand goby as a purring cat and the sound of the common goby as a woodpecker. The male fish start eladies sex creating a nest out of a hole or an empty clamshell.
When the female swims by, the male calls. If she likes what she hears, then she agrees to deposit her eggs, which the male fertilizes and then looks after until they eladies sex.Not Looking For The Perfect Woman
But, according to the research, female fish eladies sex to be able to hear the songs in order to decide where to lay their eggs. Amid the rumbling of boats and other man-made noises, the female fish may eladies sex receive the signal.
To test this idea, scientists put gobies in several separate tanks, each with two female fish and one male, and watched them attempt to reproduce. They played noise in some tanks that was at eladies sex same frequency of a leisure boat, some intermittently and some continuously, and the other eladies sex were silent. In the silent tank, 54 percent of the males received eggs.
With intermittent noise, 39 percent got eggs. With continuous noise, only 14 percent of the males eladies sex successful.
Furthermore, fish experienced several problems in noisy environment. Many of them did not mate, and those that did took longer.
Furthermore, half of the eggs died before hatching, and those eladies sex survived took longer to hatch. The fish in the silent tanks mated faster, more, and had more surviving offspring.

Even if boats are far away, they can still disrupt reproduction. Sound travels five times as fast and eladies sex long underwater.
These two goby species are integral to a healthy ecosystem, as they are a major food source for bass. Eladies sex much sound could mean fewer baby eladies sex, and fewer gobies means less food for bass, and that, in turn can have a domino effect on the rest of the animals in the area.
