Male white-spotted pufferfish create large, geometric circles on the seabed to attract females.

Lungfish and bichirs can breathe air and as such can survive outside of water for some time, while some species of eel, catfish and snakehead are capable of travelling on land. The Pacific leaping blenny can survive out of the water on moist surfaces for several hours, and leap between the rocks they live on.

Large wels catfish live in the cooling ponds and channels close to the power plant, where they are at the top of the food chain.
