Float like a butterfly? Sea Snail ‘flies’ through the water

#Cosmoread: Not a sea cow horn and an udder is not something common ocean-dwelling organisms and animal names that are completely finished with the looks. A sea lion is the lack of a tawny mane. Fish and jellyfish are not true.
But the sea butterfly, a small sea snail, according to a new study, in common with insects flying more than you can expect.

Also known as Limacina helicina, sea butterfly cold ocean waters in the North Atlantic and the Pacific region to navigate. 1 to 4 millimeters in diameter (0:04 to 0:16 inches) about its opening measures, and the use of a pair of winglike appendage swims. When threatened, it can retract into its shell.

Many types of zooplankton, tiny animals, ocean, sea butterfly-like structures, which they propel themselves through the water as the pedal is used. But the first step is for researchers to analyze how sea butterfly appendage conducted, the scientists found that the creature swam in a completely unexpected way. It’s completely unlike other zooplankton swimming movements used.

Honorary insect

“And we looked into it, and we found that sea butterfly honorary pests,” said study co-author David Murphy, the Georgia Institute

of Technology.

“We saw the wing kinematics – how it moves its wings in a figure eight pattern-and it is very similar to how a fruit fly beats its wings,” Murphy told Live Science in an email.
To capture these movements barely see, Murphy explained, four high-speed cameras, scientists have recorded the snails as they swam in an aquarium, used within an area lit by infrared laser. But as sea butterflies researchers also wanted to track the movement of the displaced water. To do this, scientists, small water seeded with light reflecting particles.
Murphy said, “each of the four cameras, thousands of these particles to determine the 3D position” “and their movement, we can measure the animal around the 3D flow.”

“Clap and click”

The researchers found that sea moves a flying butterfly common to many small insects had been using a technique called “clap and kick,” in which the animal behind it claps its wings and then they separate filings, Murphy explained. Or water flow, in the case of sea butterfly – – This airflow creates a small vortex at the tip of each wing, providing additional lift.

Wing measuring speed and water flow was not easy, Murphy said. Setup, calibration and alignment of the image capture system has taken a full day, Murphy told Live Science. To create even more challenging tests, the subjects did not actually call you strongly, he said.

“Ocean Butterflies are extremely vulnerable. They are like jellyfish-like thin, hard shell apart,” said Murphy. The West Coast shipping successfully organism, and the challenges to keep them in good condition. But luck was with the researchers, and there were swimmers not only arrived safely, but also were very cooperative, he said.

“The right to swim in front of the camera is really hard to get to the animals, but these beautifully behaved and gave us the right data,” said Murphy.
