Discovery of Shark’s Evolution

The view of shark development is that sharks first developed an initially cartilaginous skeleton that later become all cartilage. In other words, it was essentially the cartilage that came first. But now The Imperial College in London says recent fossil discoveries disproves that. The discovery is that the sharks evolved from a skeleton made of bone - rather than the cartilaginous material existing before bone. So sharks had bones and then lost them.

Cartilage gave them an evolutionary advantage. The material has around half the density of bone which made the sharks more mobile in the water and able to swim at great depths which the bony fish couldn't do.

Environmental Awareness

Surf-casters get a thrill fishing for sharks. They legitimize it by tagging the sharks to collect data. However, The South Fork Natural History Museum on Long Island says this shark fishing is destructive; the stress and exhaustion from the fight on the line — and abrasions from being dragged up the sand — can leave lasting damage and likely kill the shark. NOAA needs to end its volunteer tagging program so that there is no reason for this kind of fishing.

Pass Shark Legislation

There is something that you can do to help sharks.
Urge your U.S. Senators to support the Shark Fin Sales Elimination Act here. #FinBanNow


73 million sharks a year are killed for the ecologically damaging fin trade, and now a quarter of all sharks and rays are threatened with extinction.

We must protect them with this legislation.
Thank you for your efforts on this important issue!
Both legislative bodies of New York State have proposed bills that would make animal killing as part of contests, competitions, and tournaments illegal. The laws would prevent, for example, the killing of game and wild birds in tournaments that involve trophies or money. However, the bills as written do not include sharks.

Sharks are needlessly killed in shark tournaments and we need to protect these apex predators too. Please help make it illegal to kill sharks in fishing tournaments by signing this petition requesting that sharks be added to the protected list.

By banning shark tournaments, we are taking an important step in the conservation of our oceans ecosystem by saving sharks.

Georgia Shark Events Rare

Georgia has a lot of sharks, but shark events are very rare. The state reported seven bites between 2000-2019, a 20-year average of 0.35 bites per year. Only four coastal states haven’t reported a shark bite over the past 20 years: Alaska, Connecticut, Maryland and New Hampshire.  Georgia’s one reported bite last year occurred on the Wilmington River when a shark bit a local lawyer who was out for a swim.
