Sharks primarily live in saltwater, but some species can be found in brackish and freshwater.
Sharks and rays (Elasmobranchii) are a subclass of the cartilaginous fishes ( (Chondrichthyes). The species in this subclass have jaws, paired fins and nostrils, a heart with its chambers in series, and skeletons made of cartilage rather than bone.

Hi,
My Great Grandfather Jan Tyssen / Tijssen lost his leg in a shark bite incedent when he was 12, he was from the Netherlands and it happened on a fishing trip. Do you know of any historical data that would have information at all.
Probably around 1888 when it happened.
Thanks
Jim
Hi Jim,
There is a historical overview of shark attacks but there is a big chance not all of them are on it as this has been a long time ago. You can check it out here
Thank you Alex, I will have a look at that now 🙂
