Question: could you keep one in a pond

Lesser-Spotted Catshark answered on 7 Nov 2017:

Nope. Catsharks are marine animals and live in the sea so they wouldn’t survive in a freshwater pond. The best place to keep them, besides in the wild, are in seawater aquariums. But don’t forget they grow up to 1 metre long so you would need an aquarium almost as big as your room to keep a full-grown one happy!
