Meet the fish with his face on back to front


A turbot flatfish has a whole new outlook on life as it has developed with its head back to front.
Normally the right eye of a turbot gradually moves round next to the left, meaning they swim on their side.
But the eyes of one turbot, called Herbert, have moved the opposite way and so he swims on his left side - and the wrong direction to all the other flatfish.

The rare genetic anomaly resulted in the extraordinary event of a turbot coming face-to-face with his fellow species at the Weymouth Sea Life Centre in Dorset.
But is not all bad news for Herbert. The abnormality might also give Herbert a unique advantage in the mating stakes by enabling him to meet females.
Ed Bailey, senior aquarist at the attraction, said: ‘Herbert was lying next to one of the other turbot looking it in the face and it suddenly struck me that he shouldn’t be able to do that.

‘It was then that I noticed his eyes were on the wrong side of his head.

‘He’s certainly a bit special, and we’ve also now noticed that he often turns himself tail-to-tail with the others so he can face the same way.’

Mark Oakley, spokesman for the centrem said: ‘As Herbert is facing the other way to the other turbot he can approach food from a different direction.


‘We have noticed that every time he goes face-to-face with one of the others they quickly move away.
‘In the sea the water currents are moving in all different directions so Herbert might have an advantage in the wild because food would be swirling about from all angles, and he would be the one seeing it from a certain way.

‘We have certainly never seen a turbot like him before and I have never heard of another one with such a peculiarity.’Herbert and the five other turbot are being held in quarantine at Weymouth Sea Life Centre, but will be moved to the Brighton centre at a later date.

Turbot - Scophthalmus maximus in Latin - is a species of flatfish that is native to brackish waters of the North Atlantic, Baltic Sea and the Mediterranean.
They can grow up to 40ins long and 55lbs in weight. They are a fine eating fish and they yield four fillets.
