Sharks on sale at the La Goulette fish market

Sharks on sale at the La Goulette fish market.

Even though we tend to eat a lot of fish, as a point of principle we never buy sharks.  I cannot explain why it makes me feel sad to see sharks on sale at the La Goulette fish market.  It seems hypocritical I know, yet I find it difficult to put into words why I have this overwhelming feeling bordering on respect when it comes to sharks.  I feel sharks are much maligned and misunderstood.  As the Wikipedia extract rightly states, although sharks are "apex predators—organisms at the top of their underwater food chain. Their predatory skill fascinates and frightens humans, even though their survival is threatened by human-related activities." 



"Sharks are a group of fishes characterized by a cartilaginous skeleton, five to seven gill slits on the sides of the head, and pectoral fins that are not fused to the head.  Sharks are found in all seas and are common down to depths of 2,000m (6,600ft). They generally do not live in freshwater although there are a few known exceptions, such as the bull shark and the river shark that can survive in both seawater and freshwater.  They breathe through five to seven gill slits. Sharks have a covering of dermal denticles that protects their skin from damage and parasites in addition to improving their fluid dynamics. They also have several sets of replaceable teeth.


Well-known species such as the great white shark, tiger shark, blue shark, mako shark, and the hammerhead shark are apex predators—organisms at the top of their underwater food chain. Their predatory skill fascinates and frightens humans, even though their survival is threatened by human-related activities."
