Many people ask, “Why are sharks endangered?” There are three main human activities that have attributed to this growing concern: commercial fishing, bycatch, and habitat degeneration. These sites are places where the sharks’ food is plentiful and reliable, and often happen to be good for underwater photography. Shark researchers adapted the Groth algorithm to identify whale sharks by their spots, which form their own sorts of constellations. This shark finning is estimated to kill over 100 million sharks globally per year. Why these spots are whale shark sausage fests and whether female sharks hang out elsewhere are open questions. Let’s explore the species at risk of endangerment and the human activities that have caused this crisis in the first place. 2013-03-25 16:14:27 2013-03-25 16:14:27.

The last species that we’ll discuss is the great hammerhead shark, which has also been listed as endangered with a decreasing population. Bottom dwelling fisheries are also known to reel up sharks, since a handful of their species are bottom-dwelling fish. Much of his research work involves tagging whale sharks with radio transmitters and tracking their movements, which is complementary to the Wildbook photographic identification project. The docile, pelagicwhale shark (Rhinconodon typus) isthreatened (Listed as Vulnerable by the IUCN), not quite endangered. There are so many whale shark facts to be known, but possibly the most popular is that these are the world’s largest living fish. The latest research suggests that around 100 million sharks may be killed annually, often targeted for their fins. • Whale sharks are friendly and pose no threat to humans - … They are also used for shark fin soup, which is a delicacy in Asian countries.
