California has now conserved 25.2% of its lands and 16.2% of its coastal waters with a little more than five years left to conserve 30% of each, officials say. With 25% of state land protected ...
Sphyrna alleni, the shovelbill shark, is a species of hammerhead shark found along the West Atlantic coast from Belize to Brazil.
