Sharks have been swimming in the oceans for about 400 million years. They predate humans, dinosaurs and just about anything that walks, crawls or swims.
Sharks have been studied closely for more than a century, mainly because of their low likelihood of contracting disease. For a long time, scientists thought that sharks were immune to cancer and tumors. What makes sharks different? They don’t have bones. Their skeleton is made up of cartilage.
The shark-cartilage industry is booming because of this. Recent studies, however, have disproved the belief that sharks don’t get cancers.
Although there may not be enough evidence to suggest that ingesting shark products can have an effect on our own immune systems, we may be able to study more about how immune cells behave by studying sharks.
