Hammerhead Shark

Groundbreaking Lawsuit Pushes Mexico to Protect Hammerhead Sharks

Mexico Exported 300,000 Pounds of Hammerhead Shark Fins in Three Years


The legal action is likely the first-ever lawsuit aimed at forcing wildlife protections under NOM-059, Mexico’s equivalent of the U.S. Endangered Species Act. The suit, filed in district court in La Paz, notes that Mexico’s Secretariat of Environment and Natural Resources (Semarnat) ignored scientific evidence demonstrating that hammerheads urgently need protection, as is already recognized internationally.

Why is the hammerhead shark's head shaped like that?

Why the peculiar head shape of the hammerhead shark developed as it did has been the subject of much speculation. Few other morphological oddities have inspired so many fanciful and sensible theories about its function as the weirdly shaped head that characterises the hammerhead shark. Recent experimental evidence supports some ideas and refutes others, while pointing to a previously unsuspected role for this peculiar feature.
