Sharks are non-attackable fish found near the Ship Yard in east Karamja and in the wreckage of the Fishing Trawler. Because they swim beneath the water, they cannot be attacked. They could also be seen in the Cap'n Arnav random event. Several sharks are circling the waters around a small island with mermaids encountered in Deadliest Catch quest. Two recently added sharks can also be seen from the Water Altar by standing on the edge of the south-eastern or south-western peninsulas.
They have no character model below the water, merely consisting of the visible fin.
