I saw one show on Discovery I think it was, where they were injecting lemon sharks with cancer cells trying to get them to develop cancer. Personally i could never understand why not having bones would prevent cancer, but that has been the claim for several years.
I have caught fish that had tumors, or at least what I took for tumors, on their body and those fish went back into the water. During the fall the mullet (bait fish) run close to the granite block jetty where i like to fish, and that brings in the mackeral and the redfish. Also dolphins are close. i catch a number of reds with badly damaged tails and we think the dolphins have caught and played with them. Dolphins will do that, catch fish and toss them into the air, etc. Is amazing to see. BUT since we don't know that their tails were actually damaged (bit sore rips, etc) we also release any that have any damage.
I have read many times and seen many times that sharks do not get cancer, but as far as I know, only lemon sharks have been experimented on. maybe they are the only ones that don't get it, or are believed not to get it.
Yes, I am pretty proud of my collection of shark teeth, which numbers in the thousands as I have been picking up for 18 years. My favorite ones are the long dagger ones that come from mako and sand tiger, and the the ones that come from the regular tiger shars, the ones that come down, then curve back almost like a hook. They are the three rarest i find. Do get an awful lot of bull sharks (they are the ones that do most of the attacks on the Texas coast), hammerheads, lemon, etc. Some I have no idea what they are. I also pick up manta ray grinders wich is what they have for teeth. I do not know much about them. And I have found two fossil sand dollars that are like stone. Great find I understand.
