Was out fishing yesterday off the coast of california coming out of marina del rey about 10 miles out almost in international waters and we hit a rocky patch as we were drifting and started to catch rockfish, threw them back, the ones whose swim bladder took longer or just died drew this little guy in and he 'attacked' our boat and nudged it lol. He got in a fight or something as tendons or something was growing without skin. We couldn't tell if it was a blue shark or a thresher shark do to some of the damage and it still being young. It was a blue/purple mixture in color. Ended up eating two fish, circling us and going under us for 15 minutes then left. Wish I got video of it eating, excuse the vertical filming then flipping, was shocked when I first started filming and then when trying to correct it my phone was like 'no' we are staying vertical lol

Neither blue nor thresher ... that's a young mako shark.
We encountered one just a couple of weeks ago, off Rhode Island - the pointed, conical snout, stout body, heterocercal (lobes pretty close to the same size, top and bottom) tailfin with caudal keels on either side are keys for identification.
Beautiful animal, but this one is just little - one or two years old.
Parasitic copepods trailing from their fins are pretty common.
