Scalloped hammerheads pose no risk to us – but we pose enormous risk to them. Our discovery of a large new aggregation gives us an opportunity to protect these animals.
Megalodons are having a cultural moment. What do we know about them? And might further scientific discoveries reveal more about the true shape and size of these creatures?
Open ocean sharks are globally threatened with extinction. Knowing where they are helps us protect them. Here, new research into silky sharks reveals priorities for conservation.
Some baby sharks eat their unborn siblings in utero, while others spend 100 years in childhood. Sink your teeth into the weird world of these juvenile wonders of the deep.
