A new study reveals how a dog can hunt marine fish, even in the murky water though. The result, seals use whiskers to detect it turns out the trail left by their prey in water, up to half a minute.
The biologists found that the seals can detect prey fish in the turbidity of water left by their prey. This behavior is similar to the ground following the smell of dogs to hunt their prey.
This animal's whiskers are so sensitive, so it can detect traces left by a vortex of fish, up to within half a minute. In turbid and dirty water, seals rely solely on extra flavorings to hunt prey that try to escape.
Until now, the whiskers of seals known to only work when physically touching an object, but after closer examination, it appears that this organ is known to play a much more important.
The researchers believe the sea dog's whiskers are as effective as eccholocation to dolphins and whales that serve as prey detection.
Dr. Wolf Hanke, zoology expert at the Center for Marine Studies at the University of Rostock, Germany, said that the seals can follow in the footsteps of fish after the 35 seconds at a distance of about 230 feet (70 m).
He said, "Mustache seals have a function similar to the echolocation whales and dolphins."
Although testing is only done in general, they believe any other species such as sea lions, also enabling their whiskers like this.
The scientists claimed, they also have preliminary findings that show, the seals can even detect information about the size and speed of underwater prey in the lane.
Prof. Guido Dehnhardt, which is also based at the University of Rostock and worked on this research says, seals the possibility of using a mustache and senses of hearing to track the fish, before his eyes a few feet to the chase.
"Now we not only know, that seals can read the trail information and directions, but we also found data that showed, they can also read the size and shape of an object," he said.
"It shows that the seal's whiskers are very sensitive to touch on, as a means to explore objects that physical contact with the mustache. Information hydrodynamic sensing is something entirely different and expansion information spectrum is physically just a whisker over the response of these animals," Prof . Guido explains.
So, a dog's whiskers sea, proved to have benefits that are very useful for the continuity of life.
