Some notes on an ambivalent behaviour of the Greenland halibut Reinhardtius hippoglossoides (Walb.) Pisces: Pleuronectiformes

The ambivalent behaviour of the Greenland halibut with respect to its swimming position is discussed. The conclusion is that, when swimming close to the bottom, it swims the way all flatfishes do, viz. horizontally; when it swims freely, however, it adopts a vertical position.
