Can fish orientate themselves on land? A team of researchers is investigating this question - and has built a species-appropriate means of transport that the sea creatures steer themselves.

This fish is the driver of the vehicle - and that is his vehicle. Scientists from an Israeli university teach fishing to drive.

Equipped with sensors that can detect the position of the animal as well as that of the mobile, the movements of this goldfish are implemented on a small robot car. Whichever direction the animal moves, that is also where its aquarium goes.

“Amazingly, it doesn't take the fish long to learn how to steer the vehicle.

At first they are confused.

They don't know what is going on, but they quickly understand that there is a connection between their movement and the movement of the machine in which they are. "

Six goldfish were given around 10 driving hours each.

The final exam was passed to see who was aiming correctly at a target area - as a reward there was food.

And as with humans, there are also Sunday drivers among fish.

Ronen Segev, biologist and neuroscientist

"There were fish that behaved excellently and mediocre fish that controlled the vehicle but were less skilled with it."

With their study, the scientists want to test whether sea creatures are able to orientate themselves on land.
