ether or not fish get seasick?

Well, according to Dr Reinhold Hilbig, a zoologist from Stutgart, the answer is yes.

The boffin studied the effects of weightlessness in water as part of research into how humans are affected in space.

To reach the conclusion, forty-nine fish in a mini aquarium were sent up in a plane that went into a steep dive, simulating the loss of gravity astronauts encounter in space flight.

He said eight of the fish began turning around and around in circles.

"They completely lost their sense of balance, behaving like humans who get seasick," The Telegraph quoted Hilbig, as saying.

"The fish lost their orientation, they became completely confused and looked as if they were about to vomit. In the wild such a "seasick" fish would become prey for others because they are incapable of fleeing from danger," the expert added.

Later, the eight seasick fish were culled and their brains were analysed to try to determine the exact cause of their sickness.

"It would seem the loss of eye contact with water movement and vibrations plays a large part in their disorientation," Hilbig said
