To territory marking roe deers using chemical and optical biocommunication- breaking antlers and raking. This work is also focused on our most common fish carp. From Czech fish only carps intensive jumps out of the water, which could be one of the modes of communication. The carp is shoal fish, it lives social way of life. Carp is the most active in summer, in the summer is also the most jumps. After the data showed that carps and roe deers are oriented in the north-south axis, with a preference of north. The resulting vector in the direct observation of raking roe deers 7,5 ° and jumping carps out of the water 341.5 ° confirm magnetoreception in both species. |
