Spurdog
Spurdogs are regularly caught by fishermen. In October 2008, the fishing vessel TX68 caught many spurdogs in its net. The crew filled more than 60 crates with this shark alone. The characteristic spines, or spurs, on the front of both dorsal fins are defence weapons. This can create a problem for fishermen when trying to remove them from their nets. Otherwise, spurdogs are harmless.
