Both species are predators, they feed on fish, crustaceans, mollusks, they are indifferent to larger creatures. However, if you try to foolishly grab the same katran, say, by the tail, it can bite. At the same time, the consequences and sensations will be comparable to the bite of a dog: the jaws of the katran are quite powerful. You should be careful when touching the caught fish: its body is covered with spikes, some of them emit a weak poison. Katran is one of the most numerous inhabitants of the Black Sea. The feline shark, the scillium, is much more difficult to meet in this water area: it only occasionally appears in its Turkish part.
